What can I say, amazing 🤯 Much appreciation. I don't think you realy realise the magnitude of your work and how much you are helping the community to get the best out of their sound system 👏
Is there a chance to get something like this for a 2 way stereo system or much better for car hifi system running a raspberry pi with camilladsp??? What you are doing with REW is just amazing!!!
This is for folks who want to go full manual. It’s more involved and will yield slightly better performance. But it’s not going to be a night and day difference like plain audyssey to a1evo was.
Guys, skip to 45:00 before you take measurements. There are more settings that need to be set before you take measurements. You'll waste a lot of time if you just try to follow along with the video, then hit 45:00 and realize those settings weren't adjusted right.
First :D OCA you are amazing. We appreciate you and your countless hours of hard work more than you know. I cannot wait to watch this again later and setup my new Nexus setup!
OCD, thank you for this info. I can’t wait to try it on my Denon AVR. A question please. I intend to purchase mono blocks for my L-R speakers and an Eversolo A8. For TV surrounded, I should be able to feed the analog input of the Eversolo, using the Denon L-R preamp output, and still take advantage of the A1 Evo Nexus installation with Audyssey. But, when using the Eversolo to stream music or play a CD, the AVR will not even be on, so I need some correction for the speakers. Do you the think I can use the process of Convolution with Inversion you presented in an earlier video? The Eversolo has a DSP and they have instructions for installing REW files. For information, by connecting the system as I described, I only have one input into the mono blocks and will not need to manually switch inputs. I will use the 12v trigger from the Eversolo to turn the mono blocks on/off and the Eversolo can be controlled from my phone or iPad. Also, the DSP in the A8 is not on for the analog input, so, surround playback will not be affected by the Eversolo. Thank you, Mabe Hall.
Spent half of the last night of watching a tutorial and taking my measurements. Went to the office with red eyes :) I will do more after calibration measurements later, but I wanted to ask why it sets my both subs -8 db lower than MultEQ and A1 Maestro? I do have two SVS SB-3000 and their level is set to -17 db and -19 db, basically right in the middle of MultEQ XT scale during Audyssey calibration.
How do I do "audio sweep files" for my Auro-3D 13.1 configuration (specifically CH and TS as they are not in the Atmos files provided?) - I use a Marantz 8805A AVR not that it matters? And thank you for all the excellent calibration work - an amazing upgrade from straight Audessey; best I've ever heard my system sound!
Just went through the process. Like being able to redo measurements with rew! (Such as lowering my subwoofer to have near 0db volume adjust needed.) Worked fantastic with a umik-1, best sounding my Paradigm Signature S8 have ever sounded. Crystal clear, nice thumping bass. Did it all with DEQ at 10 offset.
It would be wonderful if John could update REW so that your Atmos sweeps could be played entirely through rew (a little playlist inside REW). That would save a lot of time spent on clicks.
@@ocaudiophile there is the sequential measurements function, perhaps that could be improved so that a single sweep file containing all speaker sweeps could be used to produce all individual speaker measurements per mic position in one click. That would be neat.
This looks amazing. But obviously it’s geared towards Denon+Marantz AVR’s. Is there any hope for other AVR’s? I use an Anthem MRX740 and would love to do this even if it’s a manual process to see what gains could be had in my system
Did I understand it correct that you have to manually sort, cross-correlation align and vector average your measurements before starting the optimization? Didn't Maestro do that automatically? 😊
@@gbye007 I see. But that sequence of procedures is what takes time. A lot of time. Would be great if you could just take the measurements, name them and let Nexus take it from there.
Man, OCA, can't wait to try this out, since your last release where so great! Question, i normally listen with -25db on my AVR, so for measurement i dial the same and 0db in REW to come out at 75db, correct?
Mr OCA I was watching your live listening with my headphones but I fall sleep but in a good way: the most amazing thing right away I start dreaming with you , in my dream my brain was listening to your live and it was like I was in a classroom paying attention to your Evo Nexus guide , I even meet you after the class ends I shook your hands to thank you for your great work.
Am I understanding you right? This program don't make corrections over 250Hz? Do you recommend to put a "curtain" of 250Hz in the Audyssey-app before sending the file back to the AVR/Processor??
Hi OCA! When I click the optimization tab, it just tells me "Checking and sorting measurements in REW..." and when i check REW only thing that happened is it just made a C-Copy and nothing else, it gets stuck. How do I fix this?
Hi OCA! Thanks so much for this. I recall, from past tutorials from you, that we can use the center speaker (when available) to align distances and calibrations in REW. For that one should choose "C" instead of "FL" or "FR"?
Thanks a lot for your amazing job ! Quick question related to sub EQ. I have one subwoofer plugged to an Antimode 8033 S2. I guess it applies some positive EQ at some point during the antimode calibration to fix some dips but I don't know how much the applied gain is ...(I know Audyssey by default can go up to +9dB - do you know the max boost for Antimode ?). Would you suggest to leave the Antimode out of the equation, sell it on Ebay and only let Nexus do the EQ ? Or can I still use Antimode with Nexus ? Many thanks again, I follow your tutorials for almost 1 year and I've improved a lot with REW thanks to you ! Cheers
@@ocaudiophile you're right it adds 2-3ms latency. However i'm especially worried about a potential boost applied to fix dips and the double EQ (Rew+antimode). I will try with and without antimode and check wavelets on REW
Thanks for this tutorial, awesome like for EVO, just a quick question, I don't understand the purpose of noDEQboost.exe, it is reading the avr level but it does something else ? could you explain ?
@@ocaudiophile what's the DEQ reference level with this new script, i.e. at what AVR volume does DEQ start operating? Is it the Audyssey default of 0 dB on the AVR volume scale, is it the volume you choose to measure at, oe is it something else (e.g. -30 dB as with A1 EVO maestro)? Personally I think the Audyssey defualt should be correct given that they have used that reference level to determine the amount of correction needed to adhere to the equal loudness contours.
Hi OCA, do we have to center the microphone before taking measurements? The reason I am asking is that my MLP is currently not centered between FR and LR. So I am wondering if it makes sense to measure by setting mic on MLP, which will not be centered OR put mic between two seats which will be centered between mains.
@@ocaudiophile ok. Thank you. Have a four seats and MLP is the 2nd seat. Currently, the FR and. FL distance measured from this seat is 13.1 and 13.6 respectively. Would that make a huge difference in sound if measured from MLP as you mentioned?
Hey OCA, I've already asked this at AVS, but the question probably got lost in the general anticipation for Nexus :) For users with TS/CH speakers: In order to be able to play the sweeps on these speakers, would it be possible if I take the sweep from e.g. FHL (or any other speaker except FR) by simply rerouting the cable from the preamp to the power amp accordingly? Thank u so much :D
Cable routing works but timing information will be wrong, needs to be manually fixed. You should be able to play TS by TML & TMR and CH by FHL FHR sweeps though?
@CorbyPage I remember that problem the days when I used to switch banana plugs before the atmos sweeps. But when I think about it, I think you're right ;)

Some people are using dummy ady files to optimize their system with Nexus and then use the level, distance, crossover settings on their systems but EQ filter implementation will not be easy with all AVR models out there.
@@ocaudiophile sounds like a great business opportunity if you could figure it out. Your methodology and thought process sounds superb. I’ve already used your subwoofer optimisation for my 3 subs and it’s awesome, actually turned off the correction with the avr to 120Hz and just use your method and mini DSP. And I gained that much I’m Wondering what else I can gain. So I’m thinking to pull this rest of it, would you: 1. Use a dummy ady file. 2. Reset my receiver ensuring no filters 3. Measure my speakers through REW, 4. Start the Nexus optimisation and see what the level, distance and crossover settings would be. 5. As for the EQ filters I don’t know how I’d do that without utilising Anthem ARC. I will fiddle around and see what’s possible
@@ocaudiophile ok I’ll give it a shot. I’ll let you know how i go. If there’s anything else you can think of let me know. Thanks again for the awesome work.
There's an error when Nexus finishes and writes the ADY file. In the script it confirms conversion of 4 subs to standard with different delays. But the ADY file shows directional with 5.58m delay for all subs
sorry i stupidly forgot t save the script, but it runs to completion confirms 4 subs to standard with correct delays but the ady file loads as directional with 5,58m delay for all 4 subs

Last version I used was A1 Evo v3. Is it worth the effort switching to nexus, if I just have the standard Audyssey mic and a 5.1 setup with 1 sub?

Noticed that the final ady has midrange compensation enabled on multieq app.
Should we take this off or leave it?
That's the spirit👍
That should be enabled only for the subs. I'll double check if there's a bug
Did you compare it to Audyssey Maestro MJ? Is the difference significant? thanks in advance!
It would be wonderful if John could update REW so that your Atmos sweeps could be played entirely through rew (a little playlist inside REW). That would save a lot of time spent on clicks.
That's not technically possible. REW is written in Java and has no access to HDMI passthrough.
