Thank you so much OCA! Best result ever in my little 'home theater'🙂, it's the first time i received a full and clear sound; that's what i imagined from the very first day i bought my nubert set-up!!! just one question: i have different versions of ADY-files on my tablet, how can i see the which one i sended to the AVR if i forgot it?
For anyone who tried this initially and had trouble: the scripts have been updated and work much better now. It's still a bit of a pita, but just follow patiently along because the results are well worth the effort.
As I am using MultEQ-X I used this tutorial for getting the EQ with REW. Therefore i measured all positions again with REW, and did the EQ-settings. In the EQ tab is an option for exporting the filters to a txt-file. This file can be imported into MultEQ-X for each speaker. Gain and distances were set from the Audyssey measurements (they fit very well). I checked the results again with REW. If MultEQ-X does everything itself, the frequency response is more inlign with the target curve. But doing REW filtering give a more defined, "punchy" bass and clearer sound. Great Video!
Auto leveling is disabled, but as I am correcting up to 500hz only it has no effect. Headroom expension is disabled, I am not using a subwoofer. And enabled boost the trim of my front speakers too much. Audyssey can boost Max. 9db, this is what I also set in Rew.
Now I'm done. It sounds great. There were some resonances that now have been corrected. I used the Bruel&Kjær instead of Harman because I like a bit less bass. And per your earlier videos I did turn DynamicEQ on, but with an offset of -15dB. Thanks again!
I while I was waiting for live stream I was copy/pasting responses to excel , then notepad then REW :) And then you come with extract file. So much thanks.
@@ocaudiophile One significant difference, I do not know if it is Iphone app or Marantz Cinema 50 difference. But when I check speaker distances, they are not under channel report, but when you expand speaker in JSON editor, fifth option is "customDistance" that has value like this, example on C speaker - customDistance: 3.009999990463257 So, it is quite precise, and this is then number I would say to use in calculations for early reflections. Also, all Cinema line of receivers and Denon's with 8 in number (2800, 3800, 4800...) have correct sound speed.
This is amaizing! really appreciate you putting this out for free for everyone to watch and learn from. I'm a bit confused about the subwoofer part, do you change the right width in the IR window + apply the EQ?
@@ocaudiophile Thanks for the response, love how you're still active here! Just to make sure I understand, after I edit the right width in the IR window, I apply the psychoacoustic smoothing between 500 hz to 20000 hz for SW1?
OCA, hello again from Canada. In this "Optimize your Immersive Audio: Atmos and Auro 3D calibration" video once you calculate the speaker distances and plug those new distances into the Json file at 50:00, you put the new distances into the "Channel Report ... distance" area of the Json file. I did this however when I transferred the resultant .ady file into my AVR all the distances show as "0"? Is that correct, or should the AVR properly show these new distances? As an experiment, I ended up deleting the new distances from the "Channel Report ... distance" area and put them in the "customDistance" area of the Json file and redownloaded into the AVR ... and these new distances did then show up in the AVR. Is this correct or will this mess things up? I apologize if you might have already explained this somewhere else, but I couldn't find a clear answer anywhere? Cheers and thanks again for your patience and assistance. Brad
Distance setting moves from customDistance to ChannelReport from receiver model to model, some models will even throw an error if Distance is set to 0. I ended up changing the script to update both in Audyssey ART video. Try the scripts in that video link if you're still experiencing problems.
Great video ! My system sounds pretty good , except for the center channel . Was not happy with male and female voices . Thanks to your exellent tutorial I was able to create a perfect center speaker , generate the center filters , "correct them" copy and alot of copy and pasting ij Jsonedit
Hey OCA, you're my hero. Thanks for help earlier with finding most recent version of REW. I wonder if you could help again as I encountered a problem with my Audyssey XT on Denon 2500h. I went through comments on your earlier clips and someone had similar issue. It seems like Auddysey app adds mic calibration AFTER uploading .ady to the app on my phone (perfect impulse brings back correction in 10k+ Hz lol). I was wondering if I could 'bake in' negative calibration to target curve so when uploading file I get correct filters added to my reciever? Thanks again mate, u do fantastic job!
Also, if I have access to UMIK-1 mic which seems to be superior to Audyssey mic, which of your clips would you suggest to follow to get my HT calibrated with? And lastly, I can't get Atmos speakers to send sound directly from my Windows. Sound that suppose to come from ceiling speakers comes out from my surrounds (basically surrounds are getting duplicated as it's 5.1.2 system). I have no issue playing sound using files you provided though. Asio4all doesn't seems to work at all, windows direct just plays stereo and for my setup only FlexiAsio seems to be working (but only up to surrounds). I've tried 2 windows PC's with Windows 10 and Windows 11 as well as Mac, but results were exactly same. Is there any step (apart from playing your files as reference) I can take to get atmos up and running in REW?
Hi OCA! Wow, thank you so much for the excellent tutorial and the files provided for practice! I've watched a lot of videos, but yours provided me with a more in-depth technical understanding than any others I've seen before :) I only have a few questions (apologies if they seem a bit dumb - I'm still learning :) ). Would you apply your Audyssey microphone calibration file - the one you created with the UMIK-2 measurements and the ACM1HB in a previous video - after importing all the 8 measurements per speaker to RAW? Is this to ensure a corrected average vector curve from the beginning? Also, what about the hidden calibration file inside the receiver you mentioned in a second video? Where and how is the best way to apply (both mic corrections) and use them? I'm looking to get the most accurate measurement values from the ACM1HB mic to start with, if possible. Or would applying the correction be unnecessary and result in an overcorrection with your method? I have another question I don't quite understand: I use your Harmon curve file for the EQ target, but not all of my speakers can use a cutoff frequency at 80 Hz. My center needs to be cut off at 100 Hz and my 4 heights at 150 Hz - both as recommended by the manufacturer. I can only set up the cutoffs inside Audyssey, so do I need different Harman curves with an adjusted cutoff at 100 and another one at 150 Hz for the EQ filters? Or does your curve in the tutorial.zip work for all speakers? And if yes, what do I need to set up inside Audyssey for the center and height cutoff frequencies? Just to let you know: my Denon X4500H seems to have the correct speed of sound at 343. If I measure my speaker distance and compare the custom distance values inside the ady file, they match the correct distance from my measured position. Thank you again and keep up the great work!
With this method, you're hacking Audyssey measurements from the ady file and they all come with mic calibration already applied so you don't need to do anything else about it. Crossover frequencies are best adjusted according to speaker specs.
@@ocaudiophile Makes sense, thank you. I have now set and adjusted everything and what else can I say, just wow! :) What a difference. The only thing I'm wondering is, why does the target level have to be so high? Couldn't I use 75 dB instead of performing "calculate target level from response", which gave me 115.75 dB, or does Audyssey adjust this when uploading the file to the receiver and if so, is it known what the target level is - 75 db? I have the feeling that everything now sounds super good, but everything also seems much too loud in total. It could just be the effect that everything is now more balanced on point. Before, I was using DynamicEQ and DynamicVolume, which I can no longer use. I understand that I can't use DynamicEQ, because of the too high bass boost - it would be nice if this could be taken into account with the adjustments and the target curve, I want to take another look at this through your other videos or do you perhaps have a quick tip for this - maybe you already showed details in another video I missed? Thank you.
@@blackIceJ That 115dB is a random number assigned to the imported impulse response by REW, responses don't carry volume information in them. EVerything is still around 75dB. You can use Dynamic EQ only if you measure and correct the speakers with Dynamic EQ on. That's not possible with this method as this uses Audyssey measurements and they are taken with DEQ off. Watch Supreme Audyssey calibration video if you want to make use of DEQ.
OCA, do i need to add a Sub trim boost after employing the suggested curve? Is there any merit to limiting correction to 500 hz after this? Is DEQ recommended to be off after, as I watch at lower volumes?
No need to add trim to sub, no need to limit correction to 500Hz. DEQ will ruin the correction results as the calibration was done on DEQ off Audyssey measurements, try dynamic volume for lower volumes or measure with REW yourself while DEQ is on. That method is explained in Audyssey ART video.
Hi OCA, I'm wondering why we need to set the it as Reference instead of flat? I notice Flat has better or punchy bass compared to Reference after the filter is applied.
Hi OCA, Where in this video "Optimize your Immersive Audio: Atmos and Auro 3D calibration" would you recommend to apply the Anti High Frequency Roll Off filter? And how exactly how do you apply it. I've worked through this video and it definitely added audible improvements, in particular to the placement of objects/effects. Music is also audibly improved with Aura 3D. Well done!! Brad
Try changing "enTargetCurveType" to 0 in the ady first. Most amps mute after that but some are claimed to be working with HF roll off completely eliminated. The other way is to multiply each and every speaker response (only the vector averages) with the anti roll off filter, apply the correction EQ filters to the results and finally multiply each filter with anti roll off filter again before exporting to the ady.
Sounds good! Thank you for your prompt detailed response ... your the best keep up the great work!! FYI, I did previously try the "enTargeCurveType" 0 and unfortunately my Denon AVR X6700H muted (no sound) as you noted. Cheers and have a great Day.@@ocaudiophile
Thank you so much. This is my first attempt at using REW as I don't have gear for it. After watching your video I was able to follow everything using the MultEQ App. After doing everything and saving .ady file and sending it to AVR, distances are at 0, speaker levels are at 0, speaker config set to large, and crossovers set to 40Hz. I tried moving the distance info from channel report to custom distance and distances are now showing in the AVR. What should I do with the speaker levels, speaker config and crossovers? Should I just leave levels at 0 but set all speakers to small and crossovers to 80? Sorry for this but if you could just clarify this one thing. You're doing great work, thank you very much.
Hello , thank for your great job . Do you have any Idea to recover the time reference into the ARC3 when you export it into REW ? With the script , I have no Time référence. So I can't check impulse and wavelet response . Thank you again for your help 🙏
The impulse responses imported should have correct timing information in them. You can probably see their IR delays in IR Windows. If you "remove IR delays" from responses, REW will move them near time 0 and record the time gaps in the Info window.
@@ocaudiophile Please try with this ARC3 file when you will have some time. (I can imagine that you are very busy with the new A1 version and all requests ! ;-) ) . I try it to check it with your importation script . I check with IR windows , no time reference -> no impulse ;-( Thank you ! drive.google.com/file/d/1xGreYmxqYb2f9wjWNz1u2nZgft6vdK5h/view?usp=drive_link
MultEQ Editor app manipulation scripts in the link in the description are updated today. "CorrectThem.html" detects and handles all subwoofer combinations (mono, dual, standard, directional)!
Question, what if you turn up the gain on the sub it self after you run Audyssey say 15db to get 90 SPL? How would you do the target curve or adjust it when doing this?
@@TheMoparbob You can always measure your speakers with REW (Room EQ Wizard) and create filters (ie just for the sub) from that. I have other videos explaining that.
Thanks Hey. I've never donated via RUclips before, but I'm doing it with your channel because I see how much effort you put into your work and making it understandable and responding to comments. Of course, I also have a question. I followed your video "Supreme Audyssey Calibration by OCA" for my Auro3D setup, and I measured the rear surround and height channels by reconnecting them to the surround ports in REW. Unfortunately, ASIO4All doesn't work at all with my laptop, and with FlexASIO, I can at least get 5.1 channels working. I followed your video "Supreme Audyssey Calibration by OCA," except for reducing the LFE volume (as that likely applies only to Dolby Atmos and not Auro). Now I'm wondering, especially regarding the rear and height channels that I measured by reconnecting, if it would be beneficial to correct my setup again using the measurement results from Audyssey (along with their microphone) using the new method. Should I use the previous measurements taken with the UMIK1 because these measurements have more data. Or is it even useful to apply the new method? Is the method from the other video of equal quality? From the other responses, I gather that it does make a difference, but I'm not entirely sure since Auro3D is not directly mentioned. The other video was about Atmos, after all. By the way, a side note: I tried to obtain AURO3D sweeps, but I'm unable to operate Pro-Tools - I tried the trial version, but it's too complicated for beginners. I also sent a direct inquiry to Auro3D via email asking if they provide test sweeps for private use, but I haven't received a response yet. What interests me is: What do you do professionally, if I may ask? Do you have the necessary expertise for this? Thank you, and greetings from Germany.
Thank you for the gesture. The filter creation technique in this video gives slightly better, more open sound compared to the inversion technique used in the Supreme Audyssey video. But measurements taken with Umik in the other method will have slightly better resolution. I'd apply this method, save it to another speaker preset and compare. You'll have very accurate speaker distance measurements for Auro with this one. Analog mics are in general better in timing than USB mics. You can still use Umik measurements for EQ if you wish. I'm in finance and this is purely a hobby for me but I hold an aeronautical engineering degree if that counts ;)
@@ocaudiophile Accuracy in distance (new measurement with audyssey to start with) over resolution of data (using the umik data) to apply the new method? What’s your opinion?
That would yield the best possible outcome. However, you will probably find out that AUdyssey mic measurements (when all 8 of them are averaged ) are not that different from Umik measurements.
This video also made me give my very first RUclips donation. This man's work is simply beyond all expectations. How many wrong things I have heard before OCA came.
@@ocaudiophile I have now completed the calibration with Audssey . I have not made any additional corrections to the subwoofers (2 pieces over both outputs of the AVR to a MiniDSP 2x4HD). In contrast to the Supreme Tutorial, you do not go into the crossover settings any further here. Should I take over the crossover settings as calculated in the other tutorial here or simply set them to 80 Hz all around?
Opening a new comment thread on this topic :) Here's my question again How would you do the calibration when you want to use directional mode (mixture of combined subwoofer as well as 2 independant subwoofers)? Here are the sample files: 2 Subs - Directional Setting: drive.google.com/file/d/1cd6cba0p1RiHTnUw95Edjp00eF3Rb6Z5/view?usp=drive_link 2 Subs - Standard Mode: drive.google.com/file/d/1cdzCMRSXGJjIgq5RLgW-W-wDhRv9dxA-/view?usp=drive_link During Measurement Audyssey will just measure one combined sub in Standard mode, while measure 2 independant subs in Directional mode. That can also be seen in the ady file. Standardmode has just measurement for the first sub, while it has independant measurements for both subs in directional mode. So what would be the best option in your opinion if I want to use directional mode? Should I time align and eq both subs independently using miniDSP? However I guess then they will loose the benefit of 2 concurrent subs eliminating standing waves. Although I would expect LFE channel to use both subs combined. So maybe it's a tradeoff between aligning 2 subs as one or correcting each sub on its own, what do you think?
The zip file linked under the video has been updated. There's a separate "CorrectThem_DirectionalSubsOnly" script for as the name suggests for directional subwoofer mode of the new series of receivers. It will upload separate EQ filters to each sub in the system as long as the filter names match the subwoofer names. For all other subwoofer configurations, including dual subs, "CorrectThem" script is still the right one to run. I also added a ReadMe.txt in the zip file explaining multiple sub handling.
Hi, OCA! Always improving with new solutions and tutorials! :) In the Audyssey base measures, most of my speakers, present huge drops in the HF. When I try to match the "target "level", between 500 Hz and 20.000 Hz I get a message from REW with "100% of the response in the match range is below the target..." thus getting the answer "no filters required". This does not allow to improve the HF of the speakers as no equalization will be applied. What should I do? In this case should anyway "generate measurement from filters" and "generate measurement from predicted"?
It's the bipole effect :() Try adding this anti-high frequency roll off filter to your filters: www.audiosciencereview.com/forum/index.php?attachments/audyssey-anti-hfr1-filter-zip.297202/
In fact, in my system there's bipole/bipole speakers (which are in in bipole mode to be in phase instead of out of phase), but the speaker above mentioned is the central (almost full range Monitor Audio Gold 350). I'll check your link, so thanks for that. Anyway what should I do in that tutorial step in the face of that REW message?
@miguelmedinaramos you can manually create a "high shelf" filter to raise the HF manual and multiply that one with the previous filters of that speaker. Don't use more gain than 2-3dB as you are actually trying to compensate for the tweeters not being directed to LP.
Thanks a lot for all your tips. The results are awesome! My home cinema never sound so better. I still have a few doubts when calculating the correct speakers' distances! ;)
@@ocaudiophile Hello. My height channels are suffering the same problem described by our friend @miguelmedinaramos so can you do a mini tutorial, as a txt file to explain how to correct it, i´m sorry but all this is new to me. Thanks in advance.
Thanks again, timing is perfect, since a friend and.myself discussed how to import audy measurents to rew. Question: can i also convert multeqx measurements files with your tool?
Hello OCA. Greetings from Portugal. Let me thank you for the amazing tutorials and for sharing your passion for the audio. I have an Auro-3d 10.2 setup with two subwoofers connected directly to the Denon receiver, i am following all the steps but i have encountered a setback with the subwoofers, at the begining when i extracted the channels response, the response of both subwoofers is treated as one, so every thing was fine until the step when i must to use the second html code "correct them" to upload the filters, the html code are expecting 12 channels, two subwoofers named SWMIX and i am stuck here because i only have 11 filters to upload. Please how can i solve this? Thanks in advance.
I have updated the "CorrectThem" file to handle two subs. Dwonload the zip file in the video link for the updated version. There are no corrections for the second sub in Audyssey but there are volume and distance adjustments relative to the first sub. You need to put extra effort to keep the relative distances and volumes if you want to keep the Audyssey sub measurment intact. The "CorrectThem" file keeps asking repeatedly for txt files after it's already finished and I will fix that soon but for now, it wiill do the job.
"You need to put extra effort to keep the relative distances and volumes if you want to keep the Audyssey sub measurment intact" This was the first time that i deal with the REW program, i dont know how i should do it, please can you advice me? Much obliged.
Thanks for sharing this video. I am struggling at generating EQ Filters with subwoofer. When i click on "Match response to target" it says: "The Range over which EQ could be applied is too narrow" with Harman Target Curve. Do i need to set the volume of my subwoofer higher?
Hi OCA, Thanks alot for the tutorials. My RHR, RHL and SRA are unable to correct from 500 - 20000 due to "The target level is more than 10 dB away from where REW's estimate of where it should be". I see a few other people in the comments have similar issues but I don't really get what to do with the 'Audyssey anti HF1 filter'. Do you mind elaborating on what to do with this file?
That's fine. Just generate the filters (there will not be any) just to keep the workflow in order otherwise you can confuse the speakers during multiplication.
Hi there! In the video you say to have midrange compensation turned off before moving the .ady file. The video you show here has midrange turned on. Was just curious if you could confirm if this and dynamic EQ should be turned off prior to extracting the .ady file?
Dynamic EQ will need to be off if you're on a Mac or using Auro 3D because you cannot measure your Atmos channels manually in REW with these systems and Audyssey measures them with Dynamic EQ off. MC should be off unless you have very old speakers. CHeck Audyssey ART video links. The newer scripts there, automatically turn these off in the ady file.
Great video! I am new to REW but following your video has helped. Question, with the older Denons that have a flaw with their calculation for speed, should I still multiply the distance in the receiver by 0.875 after the time alignment? Thanks!
@@ocaudiophile thanks! Should the receiver display the correct distance that were edited? After editing the files and JSOnline editor and sending it back to the phone to send to the receiver, the displayed distances are different. It sounds great and audio matches the TV but just wondering if I am doing something wrong. Thanks!
Hello OCA, Thanks so much for your informative videos. I am learning so much about EQing my system. I have a few questions, though: 1. In your video you adjust the SPL of the subwoofer to the Target Curve and then store the offset in the ADY file. Wouldn't it make sense to do this for all the speakers? I have the impression that some speakers are well below the TC and some above, so that I usually get a warning from REW while calculating the EQ filters. 2. My ADY file does not contain a "customLevel" property, should I just add it? 3. If I have two Subs, do you recommend first getting a miniDSP, following your other tutorial and then apply this calibration method? Thanks once again and keep up the great work!
1. I used to do it like you suggested but Audyssey sums up these speaker levels and custom target curve points (they call that auto leveling) so unless there are very visible volume differences in the speakers (can happen if your speakers are unsymmetrically placed) , it's not really necessary, eq filters do the same job. 2. You can do that but in the unlikely case that ady refuses to transfer to the AVR, then do the volume level settings in the receiver. 3. If you download the zip again, i have updated the method for two subs and added a reading text for that. Also check this link: audiosciencereview.com/forum/index.php?threads/audyssey-manual-calibration-master-stroke.46120/post-1658127
@@ocaudiophile thanks for the prompt response! 1. Only one Surround Speaker is asymmetrically placed. There are differences up to 15 dB between some speaker averages, but if the AVR will manage the levels just fine, then I am OK with that. Do I still need to adjust the SPL of the SW to the Target Curve and add this value to the ADY file, just as you show in your video? 2. I'll try adding this property by hand, in case I modify the custom level of any speaker. Else I will adjust this within the AVR after the transfer. 3. I have a Denon X3600H and it has two SW outputs, but they are managed as one AFAIK. Because of this, I cannot use Directional Bass feature. Or is there a way to upload different filters per SW, so that no miniDSP is required? (I haven't heard of such a possibility so far). Thanks for updating your code latest version of your files, so that the Dual Subs are detected correctly. If you want we can continue our conversation on ASR. :-) Kind regards!
I have a 5.1 system without auro or atmos. For the speaker distance measurements which is better. Measuring the peaks from a base speaker or leaving the original distances measured by audyssey.
Thanks for the tutorial. You are great. I have a question. The distances of the speakers are calculated, what about the volume of the individual speakers. I still have to adjust it with the SPL meter when the ADY has sent to the AVR, right?
You don't need to change the volume levels in the AVR, EQ will fix the small volume variations. AUdyssey already has set volume and crossover levels in the ady file.
@@ocaudiophile OK. Thanks for the answer. So do I just have to take over the level from the original Audyssey Ady? When I record the advanced ADY, everything is set to zero.
Hi OCA, really appreciate on your time and guide here. After all apply ady in multieq do I need to turn on the MultiEQ on my Avr for the filters to be applied on my speakers? Im using marantz cinema 50.
@ocaudiophile thanks OCA! Appreciate it! For the REW, does it always has limit of measurements that we can store? For it has limited number of measurements that I can store. If I wanna add more, i need to delete previous measurements
@ocaudiophile hi OCA. Do I need to change the amp assign in Ady file to 12? Which seems to be 11.4. Currently it is set as 1. Im using marantz cinema 50 with 5.1 system only.
Hello OCA, I was working through the Atmos and Auro 3D tutorial (again thank you for spending the time to share your lessons and experience) and got to the part where you check the distances within the .ady file. My file has no distances, for any of the speakers! Yet when I look in the AVR I can see that distances have been set (they look close to the those from my manual calibration). I know the AVR is not that accurate with the distances. Should I use the distances set in the AVR or try run the Audyssey calibration again?
If you make a couple of random edits in the "speaker detection results" in the MultEQ app measurement and then transfer it to PC, cusotm distances, levels, crosssovers will all show up in the Json editor. They only appear when there're changes in some AVR models. Btw, that info was in the notes in the video description link.
Hi OCA, First of all Merry Christmas to you and your family. I followed this video to do the measurements and all the steps. But for me I am getting echo effect from my surround speakers after I have applied the filters. Is any way you could Guide me or point me on a direction what I was doing wrong. I have 2 subwoofers on my x6500 and I just duplicate SW1 as SW2 to export into your automated scripts. Any help is appreciated.
You need to keep it as is in the ady (SWMIX). Audyssey ART video scripts are better at handling multiple subs. If you still run into problems, share your ady and I will check.
@@ocaudiophile Thank you so much for your kind response! Much appreciated.. Now I am going through the ART video. But bit confused with the 3 measurements whether at the same positions or the first 3 audyssey positions. I have shared the ady files for the audyssey original calibrations, perfect and the final one with target curves. Any help is appreciated. I was waiting for 20 years to have my home theater and it was full of disappointment. Looks like I have done too much of sound proof. Below is the link for the ady files. drive.google.com/drive/folders/1ljLv1E5h2UJ0n3yTL2pphqIWB_c_DiVJ?usp=drive_link

Thank you so much. You are my Santa for this year. Yesterday I followed ART and got a bettrr results. But still having week mid bass from LR. Will try your correction and keep you updated. Mdat would be great to learn your flow and my mistakes.
@ocaudiophile Thank you is not enough for what you have done. It is a day and night difference. Sound amazing. Only it lack little bit of mid bass. First time I am on cloud nine since I setup my home theater 18 months ago. EQ is on Reference and Dynamic EQ is ON with Reference set to 0. Is that the way it should be ? You are such a special person I met in social platforms. Thank you so much.
Hello OCA, First of all, hats off to you for putting so much efforts in creating these videos. Love the way you explained everything in detail in each of your videos. However, I do have questions on how I should calibrate my system with the knowledge you have shared in video. I have 7.2 system for now and I plan to add TF and TR height channels in a month or two. I have two subs connected to miniDSP. They are aligned and connected to sub 1 output of Denon x4800h. But I want to follow your guide to align subs using REW cross correlation features. Having said that, I have following questions. 1) should I EQ the subs after I align them using cross correlation feature and then run Audyssey to get 8 measurements to use it for the method you have described in this video? OR 2) just time align the subs and take Audyssey measurements and follow the method from this video since sub EQ is done in this video? 3) I am assuming I still have to follow the step from your other video to find the optimal crossovers for speakers. Is that correct? 4) I love dynamic EQ of Audyssey. I am not clear on what I need to do or keep in mind while calibrating the system with this method if I want to use dynamic EQ also? I will greatly appreciate your input on these questions. Once again, thank you very much for your awesome work and efforts.
Watch also Audyssey ART video, it explains your questions for using Dynamic EQ and has more evolved automation scripts. Ideally, you can use REW alignment tool to adjust your subs between each other (I have an old video on subwoofer alignment introducing a practical method), apply REW auto EQ to their sum, dial the settings in MiniDSP and do not use "custom target curve points" for the "perfect speaker" converted subwoofer output in the Audyssey ady file. However, MiniDSP usually introduces extra delays to the sub output which are difficult to optimize with speaker distance setting limits in these receivers. I ended up ditching MiniDSP altogether for this reason.
@@ocaudiophile, thank you for your response. I watched Audyssey A.R.T videos and have few more questions just so that I am clear on the steps I should follow. 1) if I remove miniDSP from the chain and connect both subs directly to sub outs, do I need to align and EQ them as per your subwoofer alignment video before following the method from Audyssey ART video? 2) since I want to use DEQ, the only option I have is to take REW measurements. Is that correct? If yes, then should I take just three Audyssey measurements to get it initial distances and level, turn off midrange compensation off, turn on DEQ and take REW measurements at 75db? Is that the correct approach? 3) if the system is calibrated with DEQ on at listen level we prefer (say -15db on AVR), does the applied EQs impact sound quality adversely if I increase master volume higher than -15db? I am sorry for too many questions. Just want to ensure I got the steps right. Thank you so much.
The answer is YES to all your questions, you've understood the methods very well. REW alignment tool is even better now (that video is a bit old) but the technique is the same. Align subs between each other for the flattest and deepest bass response. Dial the settings in the ady (relative distance and volume levels) and use the "aligned sum" as your subwoofer response to EQ in REW (the custom curve points are stored under SW1 in the ady). 3 measurements is just a way to create a dummy ady file with minimum effort, you can also use old ady files you have. Take REW measurements at the level you like to watch your movies, DEQ will help the calibration sound similar at other volume levels (google "equal loudness contours").
@@ocaudiophile Thank you. I have not had a chance to run calibration with miniDSP removed yet. I will run it today if possible and try to follow the method. Apart from this, I have a question related to step where we EQ from 500hz to 24000hz. Yesterday I tried to follow Audyssey ART steps on the existing Ady file and at this step when we try to reduce IR window to remove reflections, when I entered the number in IR window, my responses starts from 100hz onwards unlike your response which starts from around 5 hz and stays at that but the response changes. Any thoughts on what I could possibly be doing wrong? Another question, I noticed that my surround speakers are not time aligning with rest of the speakers when we try to cross correlate all speakers including subwoofer. My surrounds are Martin Logan FX. These have two tweeters in opposite direction firing in phase to provide very wide dispersion. Do you this could be the reason there are not perfectly time aligned with others?
@@spatel30 IR right window size effects the minimum frequency available and it's normal to erase low frequencies with short windows. I must have the option to show low frequencies in preferences /analytics ticked in my machine. The shown graph is invalid below a certain frequency anyways. REW auto alignment may fail with very complicated impulse responses. Try cross corr, time align, align IR starts, remove İr delays repeatedly until they align. If all fails ( happens more often than not) then measure the correct distance offset required between IR peaks with ctrl+mouse right click in overlays /impulse graph and dial that in impulse /offset t=0
Hello OCA, I calibrated my Denon 6700 for the first time with multieq app. I imported the .ady file into Json editor. All the speaker distances in channel report are : 0. This can not be correct? Thank you very much for all your videos. Greetings from Belgium.
They will all work and there are things to learn in each but to achieve a calibration with min effort, better go directly to Audyssey ART video as it has the latest scripts to accelerate the process.
Hi OCA I see that you mentioned that Multeq-X like myself can just export and apply the filters which is correct but how would we go about exporting the Audysey measurements from an MQX file which is what MultEQ-X uses? Is there a way to do this?
Your techniques look very powerful and efficacious. What mystifies me is why Audyssey doesn't do their calibration using these types of techniques. Is there something proprietary or CPU intensive that prevents the Audyssey engineers from doing this?
They sold the Audyssey license to Sound United years ago and SU doesn't seem to bother. And the cheapest chipsets can handle Audyssey's current algo and they don't want to increase the costs I guess.
Thank you for the response. This is all very generous of you. In fact, I hope you can develop it further (possibly more automation) and maybe get something back.@@ocaudiophile
Couple of tweaks I added to your approach: * Because I think the custom target curve point are offset to the reference curve, I added the HF filter to every channel (except sub) like mentioned below. * For each channel with the filters I selected the 500-2000Hz region to see what the channel does wrt to the average level. Obviously, the all lower it a bit. This nummber I manually added in the trimAdjustment field in the json to prevent Audyssey from raising the volume a bit. (I did the same for SW, but used 30-80Hz) While doing this I noticed in the JSON a referenceCurveFilter section that I did not notice before... Any idea what this is? Could this be exploited as well? 😄
The app uses it to draw the "corrected" curves. There's also one for Flat. It's supposedly a copy of the filter Audyssey will apply but doesn't have any function other than drawing graphs. I tried to manipulate it in the past to use as correction but it's totally ignored in the receiver.
Hey OCA, I wanted to check with you on 2 things: 1. Since we are still using Multeq iOS App. Is that method also taking care of the high frequency rolloff? Since we are simply using Target Curve adjustments to put in the calculated filters, it still shows the high frequency rolloff being applied in the app itself (in the curve preview). 2. I wanted to use MultEQ-X to import the generated txt file, however it doesn't work, obvioulsly it can't import the REW Filters. Is there any setting to make this happen?
@@miguelmedinaramos You have to multiply the filter with each measurfement response first before you create the EQ filters. And at the end each final filter also will need to be multiplied by it before exporting them as txt files.
@@ocaudiophile Thanks a lot for the tips. I've done it and I must say that, even with the HF roll off (just in some speakers), your settings in this tutorial sound much better with a natural Dynamic sounds ;)
Great video, I have been looking for something like this for a while! However, for two speakers I get "xx% of the response in match range is below target..." when applying EQ filters. Why is that and is there something I could do to fix it? Thanks again!
No, this is quite normal. For subwoofers for example, you will always get that. The reason is usually the response below noise level which REW includes in the response average.
@@ocaudiophile Thanks for the answer! Followed your instructions and went well until last step. When I transfer back the file to MultEQ app, all speakers are detected as full range. Also distance is 0,04 for all speakers and dB levels are 0. What did I do wrong?
Hello OCA! I have been attempting to follow your steps for a few days here. I have messed up a few times and was curious if you offered a service where I can pay to have you apply these filters to my .ady file? I'd love to give this a try!
Audyssey ART video introduces scripts that automate most of the procedure but if you're still struggling, I can try and help. And no, I don't charge for it ;)
No, you cannot, only works with Audyssey json files. You can use however parametric equalzier of Anthem and do a full manual calibration. I have a video tutorial for that: ruclips.net/video/J7mToOXTt-o/видео.html
@@ocaudiophile Thank you so much for the reply on this special day. I have added another comment. I did the caliberation and it was kind of a mess. Hearing echo ( Delayed Audio) on my surround speakers when I have the multi channel options turned on. Will you have time to have a look ar my final ady file or the initial ady file?
I have a problem that your other followers do not seem to experience. I folowed your instructions, prepared the filters and when i run correct them, exports a new ady file. I send this file to my phone but when i try to open it via the app tells me that file is either corrupted or not in correct format. Any ideas?
thank you for this video, i have 1 problem, when i am trying to upload the file from phone to audyssey app i always get this text , The specified file is not located in device storage or is not a proper curve file. do you now what the problem is?
Hi OCA, What can we do when the SW peak distance, to the LP, results superior to 6 meters (the maximum distance that Audyssey App accepts between the the shortest and highest distances measured)?
@@ocaudiophile My Center speaker is at 3,97m from the LP. In the REW measurements it gives the SW a plus 5,62m which result in a total of 9,59m (and more than 6,0m between the 2 measurements that Audyssey accepts). Here's a screenshot: drive.google.com/file/d/1nlVFKuueXtef4pGQ1DTTvLp_Xy9QyHlf/view?usp=sharing Take into account that I used the 2 subs measurements in the initial Audyssey 8 positions.
It's more than 5.62m, you need to measure the distance to the IR start which is around 15.25ms, that peak is just a HUGE reflection. You will need to enter the highest distance you can and leave it at that or change two subwoofer configuration (ie switch polarity of one of them) and check again.
Thanks again. At the moment I have the 2 subs in opposite sides (in diagonal) one at 0º and the other at 180º (phase). I'll will do tests to check it out.
Denon/Marantz has a unified Atmos & Auro configuration where the same speaker layout is used for both formats. If you're using that, is it not possible to calibrate Auro using REW with a UMIK-1 and Atmos sweeps?
@@ocaudiophile Right. But if you're using the unified configuration, such as a 7.1.4 on a Denon receiver, the calibration for the height channels is shared between the Atmos and Auro formats, or?
An Auro enthusiast forced me to create a correction method from Audyssey's own measurements due to problems playing sweeps on certain Auro specific speakers but that's all the info I have really.
OCA, I am a fan. Thanks for your sharing your knowledge in this field. Learned a lot. I have a couple of questions. I did not get the 116db SPL average. How do we know it's correct? What happens if we increase or decrease that value? If that changes the filters also change. That's why I I am asking. Thanks.
I finished implementing the steps from the entire tutorial. Very happy with the clarity. How can I apply any more bass boost to the overall curve. And, how to eliminate the HF rollout in this method? Is it all about choosing a diff house curve?
You can multiply the subwoofer filter with a low shelving filter (REW/EQ/EQ FIlters/LS) something like 80Hz/+3dB @@LordAvenger999 for more bass or use a different curve (Harmon has a bit more bass then Toole's curve). There's anti-HFR1 curve I shared in one of my Audyssey videos (can't remember which one). You need to multiply every filter with that one to eliminate HF-roll out.
@@ocaudiophilethank u so much! Will give it a try. Can you answer my earlier question about the 116db average. Does it matter what this average should be? If it is lower or higher would the filters change?
@@ocaudiophilethank you. So if we did this another time, it's possible another random spl will be assigned and we will end up with the same filters. Correct?
Has anyone experienced that when uploading from the app to the AVR, the “room data analysis”-loading bar stops in the middle? I also noticed that no “room correction results” can be seen in the calibrated.ady. Just a blank loading screen. Where did I make a mistake? `Thank you in advance and also thank you for your great videos!
You have forgotten to tick "Remove comments and headers..." during export of filters and that was causing the error. Fixed now: drive.google.com/file/d/1ce810LRvGnND1Z3etFchmXBdikHOpfiA/view?usp=sharing Btw, you have dual subs connected, it's not very easy to get distances and level settings right for dual subs. Let me know how it sounds.
@@ocaudiophile Thanks alot!!! Compared to the old (by no means bad) calibration, it's like an upgrade from mono to stereo :D What I also noticed (or questioning me) is: In the original ady.file there is neither custom level nor distance specified (level is missing/distance is 0 for all channels, although both are included in the original measurement) and in the final result ady.file (although I determined the distance according to your system and entered them) the app and the Marantz OSD both show values as zero. Do I still have to enter them manually? And finally match the channels at top level? With the Dual Subs / SWMIX I use Sub1 for a miniDSP and 4 Subs (MSO optimized) and Sub2 for an amp for the earthquake shakers. What would you recommend for this constellation? Keep the subs both as "perfect speakers" and correct them with the miniDSP? I think thats the way to get a flat anduncorrected signal for the shaker-amp. Sorry for the many questions, but thank you again :)
Hi OCA, I have viewed your video and followed every step , it took me hours to do it. Finally I want to import the filters and the PerfectSpeaker.ady file into the html page but I get a unkown Subwoofer configuration when uploading the _PerfectSpeaker.ady . I have a brand new Marantz Cinema 40 with 3 subwoofers in standard mode. The config shows 3 times a SWMIX3 in the ADY file. Can you help me out ?
I didn't have a chance to check the new 4 subwoofer configurations. The script works fine with up to 2 subs. Audyssey ART video has links to better automated scripts. If they also fail, send me your original ady file and let me see what I can do. PS You can only share google drive links in YT comments.
I have tried also the html file of your Audyssey ART video but gives the same error. I’ll share my original Ady file with the link below. Also the distances are not in the same place as you stated in the video in the JSON editor. drive.google.com/drive/folders/1DfkDP_7XPLrfrhGm-F17gefII3efrEJ-
The system is still the same. All 3 subs are aligned for distance and volume separately but there's only one correction applied to their sum. I have fixed the problem in the script but needs more testing (could now be not suitable for older 2 sub out machines) and I don't have the time today. I have created your calibrated ady file though: drive.google.com/file/d/1j2QLFMIBaBoMHJCgo_hSd30OMdT5EHwL/view?usp=sharing Just upload to MultEQ Editor app and send to your receiver and your system will sing ;)
@@ocaudiophile Hi OCA, wow this new .ady file sounds really good. I don't have to alter any crossover settings or anything ? The main L+R are set at 40Hz isn't that too low ? I was offered a Dirac Live calibration at the store were I bought the Marantz. But don't think I need it with your calibration file or is Dirac better than Audyssey? Thanks a lot for your effort of making these video's for the Home Cinema community and for the ady file for me personally.
Hey OCA, great stuff as usual. What do you think. Measuring the speaker responses via Umik1 (supreme method) then use var. smoothing in the REW eq to create the filters which then being sent to all spl via generate measurement from filters. Would that be a method to safe the manual combination method explained in the video (a*b)? Those filters can then be exported to text and converted into an ADY file to be sent to the app -> AVR? Why are you choosing another Harman Target compared to the supreme video, any experience on the resulting differences? Thanks Sir
Target curve is closely related to the smoothing applied. With 15 cycles FDW a straight sloped line works best. With 1/48 smoothing, you need the acutal Harmos. When the effect of windowing on the HF response is considered, they are in fact almost the same thing.
Hey OCA, any tipp? When I try to create a perfect ady file which based on older measurements (2 subs configured in AVR) I cannot upload the txt files (filters). Message appears please upload 11 txt files (5.4.1 setup ->2 subs as mentioned above) but I can only store one SWMIX txt file in the folder. Thanks
@@saschawehde8072 Audyssey only uses one correction regardless of the number of subs and hence the confusion. I will check the HTML code for a two sub ady file and let you know. In the mean time, you can try to upload txt file manually for the first sub.
@ocaudiophile, thanks, but I can upload nothing as long as I did not have 11 txt files to upload. So there is need to copy paste each filter same way than with the supreme audyssey calibration (Excel File). Thanks again Sir.
@@ocaudiophile yes, but most of the guys recommend min 80-110 hz crossover settings and also one guy said about my avr denon avr does not run low crossover settings which is thx standard 80hz, my denon avr x1400h does not run 80hz or below crossover settings so he suggest you maintain above 80hz settings
80Hz is accepted to be the limit where our ears begin to localise the bass so below that is safe because subs can be anywhere in the room and it will not matter. But it's not a hard set limit. Some small satellite speakers will need 120 or even 150Hz crossover points. Acoustically best XO frequency is the speakers spec -3dB/-6dB rolloff frequency.
The correction applied here is superior in sound, zero throttling. But Supreme uses Umik mics so it has the edge in the accuracy of the measured responses. A combination would be best of both worlds.
@@ocaudiophile how would you recommend combining these methods for someone that literally just did your supreme method a couple days ago? Much improved sound btw 👍
You already have the speaker measurements you did with Umik. Just try the new auto-eq filters on them rather than the inversion technique and create a new ady file. Even distances shouldn't change. It's much easier now with the HTML scripts.
@@rohan2981 Crossover determination techniques have been explained in all Audyssey videos so I didn't go over it once again in this one. You will see where to apply crossovers quite accurately in the final graphs!
@@rohan2981 Depends on your speakers. You will know their freq response and bass production limits. CHeck for -3dB given in their specs. XO freq should not be lower than that or much higher...
When I was trying 500 to 20k match, Rew showing following message "REW didn't find any filters to apply with the current match range...." Any idea how to resolve this?
This is quite common when the speaker response peaks are below the target level and nothing to worry about. That speaker simply doesn't need EQ for that region. I suggest to still generate filters and predicted response so as to keep the work flow in order. It will create flat filters. Otherwise you might get confused combining the filters at the end.
@@ocaudiophile for some reason, in second step where we generate EQ and Filter for each channel, my generated filters taking away from target curve. Original average curve is close to target curve compared to "EQ " curves after applying filters. In the video, it's mentioned generated EQ curves would be close to target curve. Is this normal? Sorry I am new to this. Any help would highly appreciated. Thank you

@@ocaudiophile sure. Will check the video. I am sharing the image of my center channel target, filters & measurements after applying 20-200 and 200-500 filters to target measurements. pasteboard.co/UbvKh7PvFpBg.png

@@ocaudiophile thanks for the video. But it's too difficult for a REW noob like me. I did my best but I am giving up after multiple tries. You are a genius with your Pc and everything looks so simple. I can sent you my file for calibration :)
You don't really need to learn REW to implement the method but I guess I have not made it as easy to understand as I thought. Anyways, if you share your ady file here, I will have a look. YT will only allow googledrive links here...
I don't know if you aware of the auto leveling behavior. If you use the Android app and change the target curve you have to readjust the trims afterwards: See also: at about 17mins 20secs ruclips.net/video/ABwtaQ8jd5g/видео.html
@@ocaudiophile I am not sure if your method really bypasses the correction. Audyssey will not try to correct any frequencies, because the fake measurements makes it think, the speakers are perfect. So far so true, but I did create some filters as you did in the video and uploaded them to my app (android). Those speakers with a filter that affects the area of 1000 Hz get an overall boost. So either the graphics in the App are wrong or the effect is present. Did someone verify that with some indepent measerements using an Umik?
@@XFUR Audyssey aligns speaker volumes depending on their frequency magnitude at 1000Hz, you can change that with customLevel key in the json, or in the app or in the receiver.
It's perfectly understandable. What I wanted to communicate with you is to see if you would kindly agree to do this calibration for me. I'm trying to understand the steps but still feel lost on the process. I have a Denon AVR X4700H with a 7.1.4 configuration. I have calibrated my subs with MiniDsp and REW. But that's as far as my understanding of calibration and PC knowledge takes me. I could send you the Audyssey file. Very respectfully I ask for your help 🙏🏼
Good afternoon OCA, hope you're doing well today. As we discussed a few weeks ago here's a link to my Audussey cal file.

Thank you so much OCA! Best result ever in my little 'home theater'🙂, it's the first time i received a full and clear sound; that's what i imagined from the very first day i bought my nubert set-up!!!
just one question: i have different versions of ADY-files on my tablet, how can i see the which one i sended to the AVR if i forgot it?
Cheers!
For anyone who tried this initially and had trouble: the scripts have been updated and work much better now.
It's still a bit of a pita, but just follow patiently along because the results are well worth the effort.
As I am using MultEQ-X I used this tutorial for getting the EQ with REW. Therefore i measured all positions again with REW, and did the EQ-settings. In the EQ tab is an option for exporting the filters to a txt-file. This file can be imported into MultEQ-X for each speaker. Gain and distances were set from the Audyssey measurements (they fit very well).
I checked the results again with REW. If MultEQ-X does everything itself, the frequency response is more inlign with the target curve. But doing REW filtering give a more defined, "punchy" bass and clearer sound.
Great Video!
MultEQ-X users here should apply this method.
Did you already use the new features of the version 1.5 like 'Disabling of auto leveling' or 'EQ headroom expansion'?
Auto leveling is disabled, but as I am correcting up to 500hz only it has no effect. Headroom expension is disabled, I am not using a subwoofer. And enabled boost the trim of my front speakers too much. Audyssey can boost Max. 9db, this is what I also set in Rew.
Now I'm done. It sounds great. There were some resonances that now have been corrected. I used the Bruel&Kjær instead of Harman because I like a bit less bass. And per your earlier videos I did turn DynamicEQ on, but with an offset of -15dB. Thanks again!
Nice work!
Thanks for being a great soul in sharing your knowledge
So nice of you
I while I was waiting for live stream I was copy/pasting responses to excel , then notepad then REW :)
And then you come with extract file.
So much thanks.
Your welcome. I couldn't try them on a Mac though, awaiting feedback on that!
@@ocaudiophile One significant difference, I do not know if it is Iphone app or Marantz Cinema 50 difference. But when I check speaker distances, they are not under channel report, but when you expand speaker in JSON editor, fifth option is "customDistance" that has value like this, example on C speaker - customDistance: 3.009999990463257
So, it is quite precise, and this is then number I would say to use in calculations for early reflections.
Also, all Cinema line of receivers and Denon's with 8 in number (2800, 3800, 4800...) have correct sound speed.
Yes you can use these values in the IR Windows.
This is amaizing! really appreciate you putting this out for free for everyone to watch and learn from. I'm a bit confused about the subwoofer part, do you change the right width in the IR window + apply the EQ?
Yes, that's the only right (ish) way to EQ high frequencies.
@@ocaudiophile Thanks for the response, love how you're still active here! Just to make sure I understand, after I edit the right width in the IR window, I apply the psychoacoustic smoothing between 500 hz to 20000 hz for SW1?

OCA, hello again from Canada.
In this "Optimize your Immersive Audio: Atmos and Auro 3D calibration" video once you calculate the speaker distances and plug those new distances into the Json file at 50:00, you put the new distances into the "Channel Report ... distance" area of the Json file. I did this however when I transferred the resultant .ady file into my AVR all the distances show as "0"? Is that correct, or should the AVR properly show these new distances?
As an experiment, I ended up deleting the new distances from the "Channel Report ... distance" area and put them in the "customDistance" area of the Json file and redownloaded into the AVR ... and these new distances did then show up in the AVR. Is this correct or will this mess things up? I apologize if you might have already explained this somewhere else, but I couldn't find a clear answer anywhere?
Cheers and thanks again for your patience and assistance.
Brad
Distance setting moves from customDistance to ChannelReport from receiver model to model, some models will even throw an error if Distance is set to 0. I ended up changing the script to update both in Audyssey ART video. Try the scripts in that video link if you're still experiencing problems.
Great video !
My system sounds pretty good , except for the center channel . Was not happy with male and female voices .
Thanks to your exellent tutorial I was able to create a perfect center speaker , generate the center filters , "correct them" copy and alot of copy and pasting ij Jsonedit

Thanks a Lot !
Hey OCA, you're my hero. Thanks for help earlier with finding most recent version of REW. I wonder if you could help again as I encountered a problem with my Audyssey XT on Denon 2500h. I went through comments on your earlier clips and someone had similar issue. It seems like Auddysey app adds mic calibration AFTER uploading .ady to the app on my phone (perfect impulse brings back correction in 10k+ Hz lol). I was wondering if I could 'bake in' negative calibration to target curve so when uploading file I get correct filters added to my reciever? Thanks again mate, u do fantastic job!
Also, if I have access to UMIK-1 mic which seems to be superior to Audyssey mic, which of your clips would you suggest to follow to get my HT calibrated with?
And lastly, I can't get Atmos speakers to send sound directly from my Windows. Sound that suppose to come from ceiling speakers comes out from my surrounds (basically surrounds are getting duplicated as it's 5.1.2 system). I have no issue playing sound using files you provided though. Asio4all doesn't seems to work at all, windows direct just plays stereo and for my setup only FlexiAsio seems to be working (but only up to surrounds). I've tried 2 windows PC's with Windows 10 and Windows 11 as well as Mac, but results were exactly same. Is there any step (apart from playing your files as reference) I can take to get atmos up and running in REW?

Hi OCA! Wow, thank you so much for the excellent tutorial and the files provided for practice! I've watched a lot of videos, but yours provided me with a more in-depth technical understanding than any others I've seen before :) I only have a few questions (apologies if they seem a bit dumb - I'm still learning :) ). Would you apply your Audyssey microphone calibration file - the one you created with the UMIK-2 measurements and the ACM1HB in a previous video - after importing all the 8 measurements per speaker to RAW? Is this to ensure a corrected average vector curve from the beginning? Also, what about the hidden calibration file inside the receiver you mentioned in a second video? Where and how is the best way to apply (both mic corrections) and use them? I'm looking to get the most accurate measurement values from the ACM1HB mic to start with, if possible. Or would applying the correction be unnecessary and result in an overcorrection with your method? I have another question I don't quite understand: I use your Harmon curve file for the EQ target, but not all of my speakers can use a cutoff frequency at 80 Hz. My center needs to be cut off at 100 Hz and my 4 heights at 150 Hz - both as recommended by the manufacturer. I can only set up the cutoffs inside Audyssey, so do I need different Harman curves with an adjusted cutoff at 100 and another one at 150 Hz for the EQ filters? Or does your curve in the tutorial.zip work for all speakers? And if yes, what do I need to set up inside Audyssey for the center and height cutoff frequencies? Just to let you know: my Denon X4500H seems to have the correct speed of sound at 343. If I measure my speaker distance and compare the custom distance values inside the ady file, they match the correct distance from my measured position. Thank you again and keep up the great work!
With this method, you're hacking Audyssey measurements from the ady file and they all come with mic calibration already applied so you don't need to do anything else about it.
Crossover frequencies are best adjusted according to speaker specs.
@@ocaudiophile thank you, sounds great! So i need different adjusted harman curve for other cutoff frequencies than 80 Hz?
The target curve will roll off with the subwoofer's response no matter which crossover frequency you choose. The bass is handled with the sub(s).
@@ocaudiophile Makes sense, thank you. I have now set and adjusted everything and what else can I say, just wow! :) What a difference. The only thing I'm wondering is, why does the target level have to be so high? Couldn't I use 75 dB instead of performing "calculate target level from response", which gave me 115.75 dB, or does Audyssey adjust this when uploading the file to the receiver and if so, is it known what the target level is - 75 db? I have the feeling that everything now sounds super good, but everything also seems much too loud in total. It could just be the effect that everything is now more balanced on point. Before, I was using DynamicEQ and DynamicVolume, which I can no longer use. I understand that I can't use DynamicEQ, because of the too high bass boost - it would be nice if this could be taken into account with the adjustments and the target curve, I want to take another look at this through your other videos or do you perhaps have a quick tip for this - maybe you already showed details in another video I missed? Thank you.
@@blackIceJ That 115dB is a random number assigned to the imported impulse response by REW, responses don't carry volume information in them. EVerything is still around 75dB. You can use Dynamic EQ only if you measure and correct the speakers with Dynamic EQ on. That's not possible with this method as this uses Audyssey measurements and they are taken with DEQ off. Watch Supreme Audyssey calibration video if you want to make use of DEQ.
OCA, do i need to add a Sub trim boost after employing the suggested curve? Is there any merit to limiting correction to 500 hz after this? Is DEQ recommended to be off after, as I watch at lower volumes?
No need to add trim to sub, no need to limit correction to 500Hz. DEQ will ruin the correction results as the calibration was done on DEQ off Audyssey measurements, try dynamic volume for lower volumes or measure with REW yourself while DEQ is on. That method is explained in Audyssey ART video.
Hi OCA, I'm wondering why we need to set the it as Reference instead of flat? I notice Flat has better or punchy bass compared to Reference after the filter is applied.
True that however Audyssey wouldn't let us use custom filters with Flat.
@ocaudiophile alright. Thanks OCA!
Hi OCA,
Where in this video "Optimize your Immersive Audio: Atmos and Auro 3D calibration" would you recommend to apply the Anti High Frequency Roll Off filter? And how exactly how do you apply it. I've worked through this video and it definitely added audible improvements, in particular to the placement of objects/effects. Music is also audibly improved with Aura 3D. Well done!!
Brad
Try changing "enTargetCurveType" to 0 in the ady first. Most amps mute after that but some are claimed to be working with HF roll off completely eliminated. The other way is to multiply each and every speaker response (only the vector averages) with the anti roll off filter, apply the correction EQ filters to the results and finally multiply each filter with anti roll off filter again before exporting to the ady.
Sounds good! Thank you for your prompt detailed response ... your the best keep up the great work!!
FYI, I did previously try the "enTargeCurveType" 0 and unfortunately my Denon AVR X6700H muted (no sound) as you noted. Cheers and have a great Day.@@ocaudiophile
Many thanks on the other hand the Dynamic EQ is activated, is it normal?
Thank you so much. This is my first attempt at using REW as I don't have gear for it. After watching your video I was able to follow everything using the MultEQ App. After doing everything and saving .ady file and sending it to AVR, distances are at 0, speaker levels are at 0, speaker config set to large, and crossovers set to 40Hz. I tried moving the distance info from channel report to custom distance and distances are now showing in the AVR. What should I do with the speaker levels, speaker config and crossovers? Should I just leave levels at 0 but set all speakers to small and crossovers to 80? Sorry for this but if you could just clarify this one thing. You're doing great work, thank you very much.
I would suggest checking out the Audyssey ART video, it has automated scripts and and XL file to ease this process.
Ok. Got it. I'll watch that video as well. I can't believe I was able to do REW following your video. Thank you again.
Hello , thank for your great job . Do you have any Idea to recover the time reference into the ARC3 when you export it into REW ? With the script , I have no Time référence. So I can't check impulse and wavelet response . Thank you again for your help 🙏
The impulse responses imported should have correct timing information in them. You can probably see their IR delays in IR Windows. If you "remove IR delays" from responses, REW will move them near time 0 and record the time gaps in the Info window.
@@ocaudiophile Please try with this ARC3 file when you will have some time. (I can imagine that you are very busy with the new A1 version and all requests ! ;-) ) . I try it to check it with your importation script . I check with IR windows , no time reference -> no impulse ;-(

MultEQ Editor app manipulation scripts in the link in the description are updated today. "CorrectThem.html" detects and handles all subwoofer combinations (mono, dual, standard, directional)!
Question, what if you turn up the gain on the sub it self after you run Audyssey say 15db to get 90 SPL? How would you do the target curve or adjust it when doing this?
@@TheMoparbob You can always measure your speakers with REW (Room EQ Wizard) and create filters (ie just for the sub) from that. I have other videos explaining that.
Thanks
Hey.
I've never donated via RUclips before, but I'm doing it with your channel because I see how much effort you put into your work and making it understandable and responding to comments.
Of course, I also have a question.
I followed your video "Supreme Audyssey Calibration by OCA" for my Auro3D setup, and I measured the rear surround and height channels by reconnecting them to the surround ports in REW. Unfortunately, ASIO4All doesn't work at all with my laptop, and with FlexASIO, I can at least get 5.1 channels working. I followed your video "Supreme Audyssey Calibration by OCA," except for reducing the LFE volume (as that likely applies only to Dolby Atmos and not Auro).
Now I'm wondering, especially regarding the rear and height channels that I measured by reconnecting, if it would be beneficial to correct my setup again using the measurement results from Audyssey (along with their microphone) using the new method. Should I use the previous measurements taken with the UMIK1 because these measurements have more data.
Or is it even useful to apply the new method? Is the method from the other video of equal quality? From the other responses, I gather that it does make a difference, but I'm not entirely sure since Auro3D is not directly mentioned. The other video was about Atmos, after all.
By the way, a side note: I tried to obtain AURO3D sweeps, but I'm unable to operate Pro-Tools - I tried the trial version, but it's too complicated for beginners. I also sent a direct inquiry to Auro3D via email asking if they provide test sweeps for private use, but I haven't received a response yet.
What interests me is: What do you do professionally, if I may ask? Do you have the necessary expertise for this? Thank you, and greetings from Germany.
Thank you for the gesture.
The filter creation technique in this video gives slightly better, more open sound compared to the inversion technique used in the Supreme Audyssey video. But measurements taken with Umik in the other method will have slightly better resolution. I'd apply this method, save it to another speaker preset and compare. You'll have very accurate speaker distance measurements for Auro with this one. Analog mics are in general better in timing than USB mics. You can still use Umik measurements for EQ if you wish.
I'm in finance and this is purely a hobby for me but I hold an aeronautical engineering degree if that counts ;)
@@ocaudiophile Accuracy in distance (new measurement with audyssey to start with) over resolution of data (using the umik data) to apply the new method? What’s your opinion?
That would yield the best possible outcome. However, you will probably find out that AUdyssey mic measurements (when all 8 of them are averaged ) are not that different from Umik measurements.
This video also made me give my very first RUclips donation. This man's work is simply beyond all expectations.
How many wrong things I have heard before OCA came.
@@ocaudiophile I have now completed the calibration with Audssey . I have not made any additional corrections to the subwoofers (2 pieces over both outputs of the AVR to a MiniDSP 2x4HD). In contrast to the Supreme Tutorial, you do not go into the crossover settings any further here. Should I take over the crossover settings as calculated in the other tutorial here or simply set them to 80 Hz all around?
Opening a new comment thread on this topic :) Here's my question again
How would you do the calibration when you want to use directional mode (mixture of combined subwoofer as well as 2 independant subwoofers)?
Here are the sample files:
2 Subs - Directional Setting: drive.google.com/file/d/1cd6cba0p1RiHTnUw95Edjp00eF3Rb6Z5/view?usp=drive_link
2 Subs - Standard Mode: drive.google.com/file/d/1cdzCMRSXGJjIgq5RLgW-W-wDhRv9dxA-/view?usp=drive_link
During Measurement Audyssey will just measure one combined sub in Standard mode, while measure 2 independant subs in Directional mode. That can also be seen in the ady file. Standardmode has just measurement for the first sub, while it has independant measurements for both subs in directional mode.
So what would be the best option in your opinion if I want to use directional mode? Should I time align and eq both subs independently using miniDSP? However I guess then they will loose the benefit of 2 concurrent subs eliminating standing waves. Although I would expect LFE channel to use both subs combined. So maybe it's a tradeoff between aligning 2 subs as one or correcting each sub on its own, what do you think?
Can you add custom curve points for both of the subs individually in directional mode in the app?
@@ocaudiophile yes i can add independant custom curves for both subs
Your reply was "held in review" by RUclips until I found it a few minutes ago!
The zip file linked under the video has been updated. There's a separate "CorrectThem_DirectionalSubsOnly" script for as the name suggests for directional subwoofer mode of the new series of receivers. It will upload separate EQ filters to each sub in the system as long as the filter names match the subwoofer names. For all other subwoofer configurations, including dual subs, "CorrectThem" script is still the right one to run. I also added a ReadMe.txt in the zip file explaining multiple sub handling.
@@ocaudiophile thank you, I will give it a try
Hi, OCA! Always improving with new solutions and tutorials! :)
In the Audyssey base measures, most of my speakers, present huge drops in the HF. When I try to match the "target "level", between 500 Hz and 20.000 Hz I get a message from REW with "100% of the response in the match range is below the target..." thus getting the answer "no filters required". This does not allow to improve the HF of the speakers as no equalization will be applied.
What should I do? In this case should anyway "generate measurement from filters" and "generate measurement from predicted"?
It's the bipole effect :()
Try adding this anti-high frequency roll off filter to your filters:
www.audiosciencereview.com/forum/index.php?attachments/audyssey-anti-hfr1-filter-zip.297202/
In fact, in my system there's bipole/bipole speakers (which are in in bipole mode to be in phase instead of out of phase), but the speaker above mentioned is the central (almost full range Monitor Audio Gold 350). I'll check your link, so thanks for that. Anyway what should I do in that tutorial step in the face of that REW message?
@miguelmedinaramos you can manually create a "high shelf" filter to raise the HF manual and multiply that one with the previous filters of that speaker. Don't use more gain than 2-3dB as you are actually trying to compensate for the tweeters not being directed to LP.
Thanks a lot for all your tips. The results are awesome! My home cinema never sound so better. I still have a few doubts when calculating the correct speakers' distances! ;)
@@ocaudiophile Hello. My height channels are suffering the same problem described by our friend @miguelmedinaramos so can you do a mini tutorial, as a txt file to explain how to correct it, i´m sorry but all this is new to me.
Thanks in advance.
Thanks again, timing is perfect, since a friend and.myself discussed how to import audy measurents to rew.
Question: can i also convert multeqx measurements files with your tool?
I am working on hacking MQX files but doesn't seem likely...
Hello OCA.
Greetings from Portugal.
Let me thank you for the amazing tutorials and for sharing your passion for the audio.
I have an Auro-3d 10.2 setup with two subwoofers connected directly to the Denon receiver, i am following all the steps but i have encountered a setback with the subwoofers, at the begining when i extracted the channels response, the response of both subwoofers is treated as one, so every thing was fine until the step when i must to use the second html code "correct them" to upload the filters, the html code are expecting 12 channels, two subwoofers named SWMIX and i am stuck here because i only have 11 filters to upload.
Please how can i solve this?
Thanks in advance.
I have updated the "CorrectThem" file to handle two subs. Dwonload the zip file in the video link for the updated version. There are no corrections for the second sub in Audyssey but there are volume and distance adjustments relative to the first sub. You need to put extra effort to keep the relative distances and volumes if you want to keep the Audyssey sub measurment intact.
The "CorrectThem" file keeps asking repeatedly for txt files after it's already finished and I will fix that soon but for now, it wiill do the job.
"You need to put extra effort to keep the relative distances and volumes if you want to keep the Audyssey sub measurment intact"
This was the first time that i deal with the REW program, i dont know how i should do it, please can you advice me?
Much obliged.
I added a new note under the video for two subs
Hi from Portugal also! Perhaps we could exchange experiences in the same language ;)
I should add Portuguese subtitles to the videos😂
Thanks for sharing this video. I am struggling at generating EQ Filters with subwoofer. When i click on "Match response to target" it says: "The Range over which EQ could be applied is too narrow" with Harman Target Curve. Do i need to set the volume of my subwoofer higher?
Either that or lower the target curve level.
Hi OCA,
Thanks alot for the tutorials. My RHR, RHL and SRA are unable to correct from 500 - 20000 due to "The target level is more than 10 dB away from where REW's estimate of where it should be".
I see a few other people in the comments have similar issues but I don't really get what to do with the 'Audyssey anti HF1 filter'. Do you mind elaborating on what to do with this file?
That's fine. Just generate the filters (there will not be any) just to keep the workflow in order otherwise you can confuse the speakers during multiplication.
Hi there! In the video you say to have midrange compensation turned off before moving the .ady file. The video you show here has midrange turned on. Was just curious if you could confirm if this and dynamic EQ should be turned off prior to extracting the .ady file?
Dynamic EQ will need to be off if you're on a Mac or using Auro 3D because you cannot measure your Atmos channels manually in REW with these systems and Audyssey measures them with Dynamic EQ off. MC should be off unless you have very old speakers. CHeck Audyssey ART video links. The newer scripts there, automatically turn these off in the ady file.
Great video! I am new to REW but following your video has helped.
Question, with the older Denons that have a flaw with their calculation for speed, should I still multiply the distance in the receiver by 0.875 after the time alignment?
Thanks!
If the real distance is 3 metres, it should show 3 x 0.875 = 2.62 metres in the receiver so that the time delay applied to this speaker is accurate.
@@ocaudiophile thanks!
Should the receiver display the correct distance that were edited?
After editing the files and JSOnline editor and sending it back to the phone to send to the receiver, the displayed distances are different. It sounds great and audio matches the TV but just wondering if I am doing something wrong. Thanks!
Hello OCA,
Thanks so much for your informative videos. I am learning so much about EQing my system.
I have a few questions, though:
1. In your video you adjust the SPL of the subwoofer to the Target Curve and then store the offset in the ADY file. Wouldn't it make sense to do this for all the speakers? I have the impression that some speakers are well below the TC and some above, so that I usually get a warning from REW while calculating the EQ filters.
2. My ADY file does not contain a "customLevel" property, should I just add it?
3. If I have two Subs, do you recommend first getting a miniDSP, following your other tutorial and then apply this calibration method?
Thanks once again and keep up the great work!
1. I used to do it like you suggested but Audyssey sums up these speaker levels and custom target curve points (they call that auto leveling) so unless there are very visible volume differences in the speakers (can happen if your speakers are unsymmetrically placed) , it's not really necessary, eq filters do the same job.
2. You can do that but in the unlikely case that ady refuses to transfer to the AVR, then do the volume level settings in the receiver.
3. If you download the zip again, i have updated the method for two subs and added a reading text for that. Also check this link:
audiosciencereview.com/forum/index.php?threads/audyssey-manual-calibration-master-stroke.46120/post-1658127
@@ocaudiophile thanks for the prompt response!
1. Only one Surround Speaker is asymmetrically placed. There are differences up to 15 dB between some speaker averages, but if the AVR will manage the levels just fine, then I am OK with that. Do I still need to adjust the SPL of the SW to the Target Curve and add this value to the ADY file, just as you show in your video?
2. I'll try adding this property by hand, in case I modify the custom level of any speaker. Else I will adjust this within the AVR after the transfer.
3. I have a Denon X3600H and it has two SW outputs, but they are managed as one AFAIK. Because of this, I cannot use Directional Bass feature. Or is there a way to upload different filters per SW, so that no miniDSP is required? (I haven't heard of such a possibility so far). Thanks for updating your code latest version of your files, so that the Dual Subs are detected correctly.
If you want we can continue our conversation on ASR. :-)
Kind regards!
@@pablo.culebras Zip file in the videos description link was updated for dual subs and there’s a readme files added.
I have a 5.1 system without auro or atmos. For the speaker distance measurements which is better. Measuring the peaks from a base speaker or leaving the original distances measured by audyssey.
Always check distances in REW Overlays/impulse graphs !
Thanks for the tutorial. You are great. I have a question. The distances of the speakers are calculated, what about the volume of the individual speakers. I still have to adjust it with the SPL meter when the ADY has sent to the AVR, right?
You don't need to change the volume levels in the AVR, EQ will fix the small volume variations. AUdyssey already has set volume and crossover levels in the ady file.
@@ocaudiophile OK. Thanks for the answer. So do I just have to take over the level from the original Audyssey Ady? When I record the advanced ADY, everything is set to zero.
Hi OCA, really appreciate on your time and guide here. After all apply ady in multieq do I need to turn on the MultiEQ on my Avr for the filters to be applied on my speakers? Im using marantz cinema 50.
Yes Audyssey should be on Reference mode.
@ocaudiophile thanks OCA! Appreciate it! For the REW, does it always has limit of measurements that we can store? For it has limited number of measurements that I can store. If I wanna add more, i need to delete previous measurements
@ocaudiophile hi OCA. Do I need to change the amp assign in Ady file to 12? Which seems to be 11.4.
Currently it is set as 1.
Im using marantz cinema 50 with 5.1 system only.
No, these settings should stay as is. You can find automation scripts for most of the manual work in Audyssey ART video
You can increase total REW measurements capacity to 300 in Preferences/View.
Thanks!
Welcome!
Hello OCA, I was working through the Atmos and Auro 3D tutorial (again thank you for spending the time to share your lessons and experience) and got to the part where you check the distances within the .ady file. My file has no distances, for any of the speakers! Yet when I look in the AVR I can see that distances have been set (they look close to the those from my manual calibration). I know the AVR is not that accurate with the distances. Should I use the distances set in the AVR or try run the Audyssey calibration again?
If you make a couple of random edits in the "speaker detection results" in the MultEQ app measurement and then transfer it to PC, cusotm distances, levels, crosssovers will all show up in the Json editor. They only appear when there're changes in some AVR models.
Btw, that info was in the notes in the video description link.
@@ocaudiophile Thank you and my apologies, I should have picked that up.
Hi OCA, First of all Merry Christmas to you and your family. I followed this video to do the measurements and all the steps. But for me I am getting echo effect from my surround speakers after I have applied the filters. Is any way you could Guide me or point me on a direction what I was doing wrong. I have 2 subwoofers on my x6500 and I just duplicate SW1 as SW2 to export into your automated scripts. Any help is appreciated.
You need to keep it as is in the ady (SWMIX). Audyssey ART video scripts are better at handling multiple subs. If you still run into problems, share your ady and I will check.
@@ocaudiophile Thank you so much for your kind response! Much appreciated.. Now I am going through the ART video. But bit confused with the 3 measurements whether at the same positions or the first 3 audyssey positions.

Thank you so much. You are my Santa for this year. Yesterday I followed ART and got a bettrr results. But still having week mid bass from LR. Will try your correction and keep you updated. Mdat would be great to learn your flow and my mistakes.
@ocaudiophile Thank you is not enough for what you have done. It is a day and night difference. Sound amazing. Only it lack little bit of mid bass. First time I am on cloud nine since I setup my home theater 18 months ago. EQ is on Reference and Dynamic EQ is ON with Reference set to 0. Is that the way it should be ? You are such a special person I met in social platforms. Thank you so much.
Hello OCA,
First of all, hats off to you for putting so much efforts in creating these videos. Love the way you explained everything in detail in each of your videos. However, I do have questions on how I should calibrate my system with the knowledge you have shared in video. I have 7.2 system for now and I plan to add TF and TR height channels in a month or two. I have two subs connected to miniDSP. They are aligned and connected to sub 1 output of Denon x4800h. But I want to follow your guide to align subs using REW cross correlation features. Having said that, I have following questions.
1) should I EQ the subs after I align them using cross correlation feature and then run Audyssey to get 8 measurements to use it for the method you have described in this video? OR
2) just time align the subs and take Audyssey measurements and follow the method from this video since sub EQ is done in this video?
3) I am assuming I still have to follow the step from your other video to find the optimal crossovers for speakers. Is that correct?
4) I love dynamic EQ of Audyssey. I am not clear on what I need to do or keep in mind while calibrating the system with this method if I want to use dynamic EQ also?
I will greatly appreciate your input on these questions. Once again, thank you very much for your awesome work and efforts.
Watch also Audyssey ART video, it explains your questions for using Dynamic EQ and has more evolved automation scripts. Ideally, you can use REW alignment tool to adjust your subs between each other (I have an old video on subwoofer alignment introducing a practical method), apply REW auto EQ to their sum, dial the settings in MiniDSP and do not use "custom target curve points" for the "perfect speaker" converted subwoofer output in the Audyssey ady file. However, MiniDSP usually introduces extra delays to the sub output which are difficult to optimize with speaker distance setting limits in these receivers. I ended up ditching MiniDSP altogether for this reason.
@@ocaudiophile, thank you for your response. I watched Audyssey A.R.T videos and have few more questions just so that I am clear on the steps I should follow.
1) if I remove miniDSP from the chain and connect both subs directly to sub outs, do I need to align and EQ them as per your subwoofer alignment video before following the method from Audyssey ART video?
2) since I want to use DEQ, the only option I have is to take REW measurements. Is that correct? If yes, then should I take just three Audyssey measurements to get it initial distances and level, turn off midrange compensation off, turn on DEQ and take REW measurements at 75db? Is that the correct approach?
3) if the system is calibrated with DEQ on at listen level we prefer (say -15db on AVR), does the applied EQs impact sound quality adversely if I increase master volume higher than -15db?
I am sorry for too many questions. Just want to ensure I got the steps right. Thank you so much.
The answer is YES to all your questions, you've understood the methods very well. REW alignment tool is even better now (that video is a bit old) but the technique is the same. Align subs between each other for the flattest and deepest bass response. Dial the settings in the ady (relative distance and volume levels) and use the "aligned sum" as your subwoofer response to EQ in REW (the custom curve points are stored under SW1 in the ady). 3 measurements is just a way to create a dummy ady file with minimum effort, you can also use old ady files you have. Take REW measurements at the level you like to watch your movies, DEQ will help the calibration sound similar at other volume levels (google "equal loudness contours").
@@ocaudiophile Thank you. I have not had a chance to run calibration with miniDSP removed yet. I will run it today if possible and try to follow the method.
Apart from this, I have a question related to step where we EQ from 500hz to 24000hz. Yesterday I tried to follow Audyssey ART steps on the existing Ady file and at this step when we try to reduce IR window to remove reflections, when I entered the number in IR window, my responses starts from 100hz onwards unlike your response which starts from around 5 hz and stays at that but the response changes. Any thoughts on what I could possibly be doing wrong?
Another question, I noticed that my surround speakers are not time aligning with rest of the speakers when we try to cross correlate all speakers including subwoofer. My surrounds are Martin Logan FX. These have two tweeters in opposite direction firing in phase to provide very wide dispersion. Do you this could be the reason there are not perfectly time aligned with others?
@@spatel30 IR right window size effects the minimum frequency available and it's normal to erase low frequencies with short windows. I must have the option to show low frequencies in preferences /analytics ticked in my machine. The shown graph is invalid below a certain frequency anyways.
REW auto alignment may fail with very complicated impulse responses. Try cross corr, time align, align IR starts, remove İr delays repeatedly until they align. If all fails ( happens more often than not) then measure the correct distance offset required between IR peaks with ctrl+mouse right click in overlays /impulse graph and dial that in impulse /offset t=0
Hello OCA, I calibrated my Denon 6700 for the first time with multieq app. I imported the .ady file into Json editor. All the speaker distances in channel report are : 0. This can not be correct? Thank you very much for all your videos. Greetings from Belgium.
Unless you edit these settings in the app they will show 0. There's more info on that in the Audyssey ART video
When loading the harmon curve you set speaker type to none, is there a reason it's not set to bass limited and subwoofer.
REW ignores speaker type when calculating target level.
Hello i want to do your other video (the supreme audyssey cali by oca) and then this video, but can i skip that and use this video?
They will all work and there are things to learn in each but to achieve a calibration with min effort, better go directly to Audyssey ART video as it has the latest scripts to accelerate the process.
Hi OCA
I see that you mentioned that Multeq-X like myself can just export and apply the filters which is correct but how would we go about exporting the Audysey measurements from an MQX file which is what MultEQ-X uses?

Normally they come to my mail but nothing did!
Ok I got it now, will check tomorrow and get back to you.
Hey sir, what method would you think is better now. This one or your "Supreme Audyssey Calibration" from early 2023?
All improve the sound significantly over standard Audyssey calibration but Audyssey ART video links have the most advanced scripts.
Your techniques look very powerful and efficacious. What mystifies me is why Audyssey doesn't do their calibration using these types of techniques. Is there something proprietary or CPU intensive that prevents the Audyssey engineers from doing this?
They sold the Audyssey license to Sound United years ago and SU doesn't seem to bother. And the cheapest chipsets can handle Audyssey's current algo and they don't want to increase the costs I guess.
Thank you for the response. This is all very generous of you. In fact, I hope you can develop it further (possibly more automation) and maybe get something back.@@ocaudiophile
Already done, did you check the Audyssey ART video?@@gbye007
Couple of tweaks I added to your approach:
* Because I think the custom target curve point are offset to the reference curve, I added the HF filter to every channel (except sub) like mentioned below.
* For each channel with the filters I selected the 500-2000Hz region to see what the channel does wrt to the average level. Obviously, the all lower it a bit. This nummber I manually added in the trimAdjustment field in the json to prevent Audyssey from raising the volume a bit. (I did the same for SW, but used 30-80Hz)
While doing this I noticed in the JSON a referenceCurveFilter section that I did not notice before... Any idea what this is? Could this be exploited as well? 😄
The app uses it to draw the "corrected" curves. There's also one for Flat. It's supposedly a copy of the filter Audyssey will apply but doesn't have any function other than drawing graphs. I tried to manipulate it in the past to use as correction but it's totally ignored in the receiver.
@@ocaudiophile The picture I was referring to is the "before" graph. This should be a straight line, right?
Yes "Room Correction Results" graphs
Hey OCA, I wanted to check with you on 2 things:
1. Since we are still using Multeq iOS App. Is that method also taking care of the high frequency rolloff? Since we are simply using Target Curve adjustments to put in the calculated filters, it still shows the high frequency rolloff being applied in the app itself (in the curve preview).
2. I wanted to use MultEQ-X to import the generated txt file, however it doesn't work, obvioulsly it can't import the REW Filters. Is there any setting to make this happen?
I created an anti-HFR1 filter for REW if you like:

Hi OCA,
I which step in your tutorial should I apply this anti-HFR1 filter? Thanks a lot
@@miguelmedinaramos You have to multiply the filter with each measurfement response first before you create the EQ filters. And at the end each final filter also will need to be multiplied by it before exporting them as txt files.
@@ocaudiophile Thanks a lot for the tips. I've done it and I must say that, even with the HF roll off (just in some speakers), your settings in this tutorial sound much better with a natural Dynamic sounds ;)
Great video, I have been looking for something like this for a while! However, for two speakers I get "xx% of the response in match range is below target..." when applying EQ filters. Why is that and is there something I could do to fix it? Thanks again!
No, this is quite normal. For subwoofers for example, you will always get that. The reason is usually the response below noise level which REW includes in the response average.
@@ocaudiophile Thanks for the answer! Followed your instructions and went well until last step. When I transfer back the file to MultEQ app, all speakers are detected as full range. Also distance is 0,04 for all speakers and dB levels are 0. What did I do wrong?
That's normal and expected with "perfect speaker" responses in the ady.
@@ocaudiophile So then I should correct the distance and dB levels once again in the MultEQ app?
Hello OCA! I have been attempting to follow your steps for a few days here. I have messed up a few times and was curious if you offered a service where I can pay to have you apply these filters to my .ady file? I'd love to give this a try!
Audyssey ART video introduces scripts that automate most of the procedure but if you're still struggling, I can try and help. And no, I don't charge for it ;)
@@ocaudiophile thank you. I’ll look at that video! Does it work on Mac as well?
All scripts are browser based html and should work in every platform.
Hi OCA! Can I use this guide with anthem room correction .arc3 files?
No, you cannot, only works with Audyssey json files. You can use however parametric equalzier of Anthem and do a full manual calibration. I have a video tutorial for that:
ruclips.net/video/J7mToOXTt-o/видео.html
So I got MultEQ-X. Could you make an ultimate calibration guide for that?
Not until they remove DEQ surround boost ;)
My center which is also a tower not having any match range below target from 200Hz to 20000Hz. Am I doing something wrong?
You should increase its volume maybe?
@@ocaudiophile Thank you so much for the reply on this special day. I have added another comment. I did the caliberation and it was kind of a mess. Hearing echo ( Delayed Audio) on my surround speakers when I have the multi channel options turned on. Will you have time to have a look ar my final ady file or the initial ady file?
Sure, share a google drive link here...
I have a problem that your other followers do not seem to experience. I folowed your instructions, prepared the filters and when i run correct them, exports a new ady file. I send this file to my phone but when i try to open it via the app tells me that file is either corrupted or not in correct format. Any ideas?
Watch my latest video posted today. Your problem will be solved.
@@ocaudiophile Thanks. Just saw it on the list. I will watch it then 😊
I tried dropping a ".mqx" file in (MultEQ-X) and it looks quite different. Is this normal...as the descriptions in JSON are different? 😢
.mqx is also a json file but the measurements (and the mic calibration file) in it are encrypted! :(
@@ocaudiophile So it doesn't work with MultEQ-X ...got it!
thank you for this video, i have 1 problem, when i am trying to upload the file from phone to audyssey app i always get this text , The specified file is not located in device storage or is not a proper curve file. do you now what the problem is?
Your filter txt files are not comma separated probably.
Probably too late to see this, but I had same issue... I found you have to use Google Drive.
Hi OCA,
What can we do when the SW peak distance, to the LP, results superior to 6 meters (the maximum distance that Audyssey App accepts between the the shortest and highest distances measured)?
You can use the first peak of the SW that's in the same direction with the speakers.
@@ocaudiophile My Center speaker is at 3,97m from the LP. In the REW measurements it gives the SW a plus 5,62m which result in a total of 9,59m (and more than 6,0m between the 2 measurements that Audyssey accepts). Here's a screenshot:
drive.google.com/file/d/1nlVFKuueXtef4pGQ1DTTvLp_Xy9QyHlf/view?usp=sharing
Take into account that I used the 2 subs measurements in the initial Audyssey 8 positions.
It's more than 5.62m, you need to measure the distance to the IR start which is around 15.25ms, that peak is just a HUGE reflection. You will need to enter the highest distance you can and leave it at that or change two subwoofer configuration (ie switch polarity of one of them) and check again.
Thanks again. At the moment I have the 2 subs in opposite sides (in diagonal) one at 0º and the other at 180º (phase). I'll will do tests to check it out.
Denon/Marantz has a unified Atmos & Auro configuration where the same speaker layout is used for both formats. If you're using that, is it not possible to calibrate Auro using REW with a UMIK-1 and Atmos sweeps?
You don't have access to TS (voice of God channel) and CH (center height) as these channels only exist in Auro.
@@ocaudiophile Right. But if you're using the unified configuration, such as a 7.1.4 on a Denon receiver, the calibration for the height channels is shared between the Atmos and Auro formats, or?
@isak6626 i don't have Auro, you can test the supplied atmos sweeps and check if there's a workaround.
@@ocaudiophile The same speakers are used for both Atmos and Auro with the unified configuration, so it ought to work :)
An Auro enthusiast forced me to create a correction method from Audyssey's own measurements due to problems playing sweeps on certain Auro specific speakers but that's all the info I have really.
OCA, I am a fan. Thanks for your sharing your knowledge in this field. Learned a lot. I have a couple of questions. I did not get the 116db SPL average. How do we know it's correct? What happens if we increase or decrease that value? If that changes the filters also change. That's why I I am asking. Thanks.
I finished implementing the steps from the entire tutorial. Very happy with the clarity. How can I apply any more bass boost to the overall curve. And, how to eliminate the HF rollout in this method? Is it all about choosing a diff house curve?
You can multiply the subwoofer filter with a low shelving filter (REW/EQ/EQ FIlters/LS) something like 80Hz/+3dB @@LordAvenger999 for more bass or use a different curve (Harmon has a bit more bass then Toole's curve).
There's anti-HFR1 curve I shared in one of my Audyssey videos (can't remember which one). You need to multiply every filter with that one to eliminate HF-roll out.
@@ocaudiophilethank u so much! Will give it a try. Can you answer my earlier question about the 116db average. Does it matter what this average should be? If it is lower or higher would the filters change?
REW assigns a random SPL level to the imported impulse responses, they do not have dB volume information in them.@@LordAvenger999
@@ocaudiophilethank you. So if we did this another time, it's possible another random spl will be assigned and we will end up with the same filters. Correct?
Why would you automatically turn off MRC? Some speakers need it.
The method does not boost any dips beyond 200Hz
@@ocaudiophile Ah, thank you.
Sir this is too much work and need skills for this can any one do it for me( i can pay for him ) i have both add.x , and Rew files
When you hear your system after calibration, It will be worth all the work!
Has anyone experienced that when uploading from the app to the AVR, the “room data analysis”-loading bar stops in the middle? I also noticed that no “room correction results” can be seen in the calibrated.ady. Just a blank loading screen.
Where did I make a mistake? `Thank you in advance and also thank you for your great videos!

You have forgotten to tick "Remove comments and headers..." during export of filters and that was causing the error. Fixed now:

Btw, you have dual subs connected, it's not very easy to get distances and level settings right for dual subs. Let me know how it sounds.
@@ocaudiophile will be tried tonight :) Will report back :) Thanks so much :D
@@ocaudiophile Thanks alot!!!
Compared to the old (by no means bad) calibration, it's like an upgrade from mono to stereo :D
What I also noticed (or questioning me) is:
In the original ady.file there is neither custom level nor distance specified (level is missing/distance is 0 for all channels, although both are included in the original measurement) and in the final result ady.file (although I determined the distance according to your system and entered them) the app and the Marantz OSD both show values as zero. Do I still have to enter them manually?
And finally match the channels at top level?
With the Dual Subs / SWMIX I use Sub1 for a miniDSP and 4 Subs (MSO optimized) and Sub2 for an amp for the earthquake shakers. What would you recommend for this constellation? Keep the subs both as "perfect speakers" and correct them with the miniDSP? I think thats the way to get a flat anduncorrected signal for the shaker-amp.
Sorry for the many questions, but thank you again :)
Hi OCA, I have viewed your video and followed every step , it took me hours to do it. Finally I want to import the filters and the PerfectSpeaker.ady file into the html page but I get a unkown Subwoofer configuration when uploading the _PerfectSpeaker.ady . I have a brand new Marantz Cinema 40 with 3 subwoofers in standard mode. The config shows 3 times a SWMIX3 in the ADY file. Can you help me out ?
I didn't have a chance to check the new 4 subwoofer configurations. The script works fine with up to 2 subs. Audyssey ART video has links to better automated scripts. If they also fail, send me your original ady file and let me see what I can do. PS You can only share google drive links in YT comments.
I have tried also the html file of your Audyssey ART video but gives the same error. I’ll share my original Ady file with the link below. Also the distances are not in the same place as you stated in the video in the JSON editor. drive.google.com/drive/folders/1DfkDP_7XPLrfrhGm-F17gefII3efrEJ-
The system is still the same. All 3 subs are aligned for distance and volume separately but there's only one correction applied to their sum. I have fixed the problem in the script but needs more testing (could now be not suitable for older 2 sub out machines) and I don't have the time today. I have created your calibrated ady file though:

Just upload to MultEQ Editor app and send to your receiver and your system will sing ;)
@@ocaudiophile Hi OCA, wow this new .ady file sounds really good. I don't have to alter any crossover settings or anything ? The main L+R are set at 40Hz isn't that too low ?
I was offered a Dirac Live calibration at the store were I bought the Marantz. But don't think I need it with your calibration file or is Dirac better than Audyssey? Thanks a lot for your effort of making these video's for the Home Cinema community and for the ady file for me personally.
@MrDverduyn the graphs point to 40hz probably due to wall proximity. Dirac is not configurable like Audyssey.
Hey OCA, great stuff as usual. What do you think. Measuring the speaker responses via Umik1 (supreme method) then use var. smoothing in the REW eq to create the filters which then being sent to all spl via generate measurement from filters. Would that be a method to safe the manual combination method explained in the video (a*b)? Those filters can then be exported to text and converted into an ADY file to be sent to the app -> AVR? Why are you choosing another Harman Target compared to the supreme video, any experience on the resulting differences? Thanks Sir
Target curve is closely related to the smoothing applied. With 15 cycles FDW a straight sloped line works best. With 1/48 smoothing, you need the acutal Harmos. When the effect of windowing on the HF response is considered, they are in fact almost the same thing.
Hey OCA, any tipp? When I try to create a perfect ady file which based on older measurements (2 subs configured in AVR) I cannot upload the txt files (filters). Message appears please upload 11 txt files (5.4.1 setup ->2 subs as mentioned above) but I
can only store one SWMIX txt file in the folder. Thanks
@@saschawehde8072 Audyssey only uses one correction regardless of the number of subs and hence the confusion. I will check the HTML code for a two sub ady file and let you know. In the mean time, you can try to upload txt file manually for the first sub.
@ocaudiophile, thanks, but I can upload nothing as long as I did not have 11 txt files to upload. So there is need to copy paste each filter same way than with the supreme audyssey calibration (Excel File). Thanks again Sir.
I will fix that, give me some time, very busy day today!
In this video all ok but how to find proper crossover settings?
It's best to set them up according to speaker spec. bass roll off frequencies from an acoustical point of view.
@@ocaudiophile ok for instance my speaker crossover is 50hz so i will set it to 60hz crossover in my avr right?
@avsolutions212 Yes, in the case of lack of availability of the precise frequency, selecting closest higher slot is advised.
@@ocaudiophile yes, but most of the guys recommend min 80-110 hz crossover settings and also one guy said about my avr denon avr does not run low crossover settings which is thx standard 80hz, my denon avr x1400h does not run 80hz or below crossover settings so he suggest you maintain above 80hz settings
80Hz is accepted to be the limit where our ears begin to localise the bass so below that is safe because subs can be anywhere in the room and it will not matter. But it's not a hard set limit. Some small satellite speakers will need 120 or even 150Hz crossover points. Acoustically best XO frequency is the speakers spec -3dB/-6dB rolloff frequency.
Is this method superior to your supreme audessey calibration method, equal, or inferior?
The correction applied here is superior in sound, zero throttling. But Supreme uses Umik mics so it has the edge in the accuracy of the measured responses. A combination would be best of both worlds.
@@ocaudiophile how would you recommend combining these methods for someone that literally just did your supreme method a couple days ago? Much improved sound btw 👍
You already have the speaker measurements you did with Umik. Just try the new auto-eq filters on them rather than the inversion technique and create a new ady file. Even distances shouldn't change. It's much easier now with the HTML scripts.
@@rohan2981 Crossover determination techniques have been explained in all Audyssey videos so I didn't go over it once again in this one. You will see where to apply crossovers quite accurately in the final graphs!
@@rohan2981 Depends on your speakers. You will know their freq response and bass production limits. CHeck for -3dB given in their specs. XO freq should not be lower than that or much higher...
When I was trying 500 to 20k match, Rew showing following message "REW didn't find any filters to apply with the current match range...." Any idea how to resolve this?
This is quite common when the speaker response peaks are below the target level and nothing to worry about. That speaker simply doesn't need EQ for that region. I suggest to still generate filters and predicted response so as to keep the work flow in order. It will create flat filters. Otherwise you might get confused combining the filters at the end.
@@ocaudiophile for some reason, in second step where we generate EQ and Filter for each channel, my generated filters taking away from target curve. Original average curve is close to target curve compared to "EQ " curves after applying filters. In the video, it's mentioned generated EQ curves would be close to target curve. Is this normal? Sorry I am new to this. Any help would highly appreciated. Thank you
I am not sure I understood the problem but you can find AUdyssey ART video useful for more (and slightly different) details to the method@@Harikrishnakanchi

When I am setting the filters I get this message: There are no free positions for the "filters" measurement. How can I fix this because I can't go on. Thanks in advance
Increase number of measurements in preferences /view tab. It will require a restart so save your mdat first
@@ocaudiophile thanks for the video. But it's too difficult for a REW noob like me. I did my best but I am giving up after multiple tries. You are a genius with your Pc and everything looks so simple. I can sent you my file for calibration :)

Thanks in advance, this would be great!!!!
Ok but I need some time, a bit busy day for me today...
I don't know if you aware of the auto leveling behavior. If you use the Android app and change the target curve you have to readjust the trims afterwards:
See also: at about 17mins 20secs
ruclips.net/video/ABwtaQ8jd5g/видео.html
That's optional in the latest X version but none of that is of concern in this method as it completely bypasses Audyssey correction and target curves.
@@ocaudiophile I am not sure if your method really bypasses the correction. Audyssey will not try to correct any frequencies, because the fake measurements makes it think, the speakers are perfect. So far so true, but I did create some filters as you did in the video and uploaded them to my app (android). Those speakers with a filter that affects the area of 1000 Hz get an overall boost. So either the graphics in the App are wrong or the effect is present. Did someone verify that with some indepent measerements using an Umik?
@@XFUR Audyssey aligns speaker volumes depending on their frequency magnitude at 1000Hz, you can change that with customLevel key in the json, or in the app or in the receiver.
@@ocaudiophile Can you also name the frequency that is used in case of the subwoofer?
