Great video for beginners. As most would opt for the umik-1 microphone, I'd extend the video with how to download and load the 90 degree calibration file into REW before measuring.
Agreed. The entire process is pointless without the implementation of the calibration files. Also an explanation of the difference between the two different calibration files and how to use them would be great.
It would be nice to know what to look for in the waterfall and spectorgram plots so we can see what needs to be addressed and the improvements made after treatments are installed.
@@halrichard1969more important, what will I do with the result? Tons of videos on how to REW few to none how to work with the result eg use EQ for your speakers.
whats the recommened way to connect this to my amp which drives the speakers? In this example it looks like the speakers adre directly connected to the PC running the software
Thank you for this video it's a great help. I Am going back for another round of measurements of my room and have always taken 3 measurements: Left Speaker, Right Speaker and Both. Why do you say the only measurements you want are of the left and right by themselves? When we are listening/working in our room I assume everyone has both speakers on at the same time. Why wouldn't we want a measurement of the room in the exact same state? Thank you again.
Should the approach be to take measurements in a number of different listening positions in order to determine the best listening position PRIOR to prescribing acoustic treatment? Also should the approach include experimenting with different speaker locations?
Thanks a lot for this tutorial. I have maybe silly question, forgive me…how do I connect REW to my sound-system, laptop’s USB output to DAC’s USB input?
Thank you for the informative video. Can you please comment on how to apply the microphone calibrations [UMIK-1] and which of the two calibration files should I use? Thanks!
For the umik1 you will be able to download two calibration files based on the serial number of your specific microphone. Usually for REW you will use the 90 degree file and the microphone should be pointed straight up (90 degrees) to hear all the sound waves in the room (and placed in your main listening position at ear level). I believe the other file would be used if you are trying to measure a speaker without room impact and in that case the microphone would be a few inches from the speaker and pointed directly at the speaker and parallel to the ground (0 degrees).
Alright, im new to this so be gental. Im a bit confused and im lookibg for a bit of clarity. I have a pair of Kef Q350's, a Denon X1800H and will be adding a Rythmik 12 inch sub very soon. If I use the USB mic, this program and my laptop to get my room measurments to correct any issues what content am I playing for play back from my AVR in order to get said measurments? Am I missing something in this video?
I want to measure all 5 ear level speakers, how do I get the Center and side surrounds? You just did the left and right front speakers? Should the receiver level be set at reference level? Should speaker levels in the AVR be set at 0.0? I need details!
Does it only make sense to measure at the listening position? Why wouldn’t you use both L and R speakers for output during measuring since this is how sound with always enter the room?
It would be immensely helpful to highlight (color, circle etc.) where the cursor is when you are telling us what to click. I know you know where you are at and what box you are in but some of us can’t see the cursor at the speed you are going and if we pause it we can’t find it at all. Also, the background music is definitely distracting when you are trying to concentrate on a fairly complicated task.
@@GunnyPhillips What happens if your AVR (in my case an old Rotel RSP 1066) is older and doesn't support this direct connection? Is it the same thing to manually run through the test tones on the processor?
It's not meant to tell _you_ anything. It's meant for you to send to them where they have engineers who understand what they're looking at. So, you take the measurements, send in the results, and pay them for the service of advising you on how to acoustically treat the room you measured. I'm pretty sure that's how this works..
@@SineEyed I appreciate you, but that's what I was trying to do is understand what I'm looking at lol. I was trying to acoustically treat a room, but it worked out I figured it all out. Thanks for getting back with me though, no joke.
Omg im going insain rew dose not work well it stops workingæ and i guess jead set mic dose not work i guess i have to wait is there any cheaper optiom then the unik 1?. Or do i need the version that cost 10$ cus it looks nice if it just worked
Thank you for this video. I have the minidsp umik-1 microphone and am trying to pick up impact noise from the floor above. Is there simply a playback option of the sounds captured?
This looks to be out of my paygrade. I could do all this, send the results to GIK and get the recommendations on room treatment but....they won't be realistic for a home studio. I think I'll continue listening to stuff I know very well through various playback devices and h/phones then calibrate my A7x Adam monitors by ear. I've already done placement. No hurry....small moves. If I need a studio, I'll book a studio, engineer and maybe producer. I don't think "Abbey Road" is realistic in a home set up and sound checking an acoustic guitar yourself from within a forest of microphones is a huge pain in the butt no matter what treatment the room has. Thanks. Lots of feedback about **** background music and I agree. There's a bit of a difference between posting "interlude music" (which is what GIK are doing here) and a bit of "background". All you need is the faintest pulse of rhythm at heartbeat tempo and the simplest possible repetitious melody - way, way down low - to energise a video. Definitely avoid any "category" or genre - such as synth rock to drum software. What we have here is........amateurish and intrusive but.........thanks.
@@SineEyed of course. But if you’re always going to be listening to these interfering sound waves when playing music, why not test frequency response playing both speakers? That’s my question
As others have said a good video .....but the backing music is way too loud - fine for a sales video but this is a technical instructive video and it's very distracting ...especially to people who spend all day doing critical listening!
The background music playing is very annoying, and competing with your voice. It takes away the quality of your video. Please take my comments as constructive, thank you.
I would think that in the making of this video the author would have understood that because he has an accent he might be difficult to understand and would have thought to slow his speach down a tad so those of us with not so good hearing wouldn't have to use close captioning...Oh and the background music is too distracting...
I think the video was intended just for analysis for their engineer to give users some suggestions, probably also based on their room photos. Then the final measurement will be done for final correction.
Thank you for the informative video. Might I suggest you reduce the horrible background music? We are audiophiles after all...
Agree, loud background music is a problem spread across most RUclips videos. Background music should stay what its meant to be: background music !
Ha!
They were editing this video in untreated room :D
Yeah, it really stinks.
That's the only reason I came to the comments. I barely made it thru the video that music was so bad and poorly mixed.

Thanks, it would be great to get a video explaining what to look for, how to understand what you see, what would be an ideal graph.

@@DieTabbi Did you find something ? I do measures but after ??
nicely done. i would only suggest adding a view of impulse response to consider addressing reflections.
actually the best representation of what we hear is the psychoacoustic frequency response!

4:25 - What specifically are we to look for when enabling PHASE with respect to the Frequency Response plot?

It produces a (very quick) sound sweep and records it at the same time.
I want to measure all 5 ear level speakers, how do I get the Center and side surrounds? You just did the left and right front speakers? Should the receiver level be set at reference level? Should speaker levels in the AVR be set at 0.0? I need details!

Should these measurements be taken with room correction disabled?
Great content !
4:24 you can also hold both mouse buttons and drag
Could this applied for beamforming ceiling mics for voice lift application? If so, what do we look out for?
Newbie-phile question. Are you referring to the computer speakers or the stereo speakers?
Thanks you!
You install the microphone to your PC but how do you get the speakers to play the tone? They are connected to the AVR.
PC has to also be connected to the AVR in some way. Usually this is done via HDMI.
@@GunnyPhillips What happens if your AVR (in my case an old Rotel RSP 1066) is older and doesn't support this direct connection? Is it the same thing to manually run through the test tones on the processor?
Not sure how you'd address that but I'd bet there's an answer out there. Just search REW FAQ's.
Can I use Rew to measure a big room, like church or conference hall ?
Yes
thank you for this video...this microphones need calibration no ?
Yes and the interface
interface ?
Did you put in cal file 😂 and where to put it? Thanks
I tried to follow this but received a message saying my soundcard hadn't been calibrated?
I'm still not sure what this graph is actually telling me, so it is measuring the sound pressure level of the room, but what for?

"Lef and Right" limit means "Lower and Upper" frequency limit here on waterfall? What a strange confusing name for that.
The word "understand" is spelled wrong in the thumbnail. (sorry)
Thank you for this video. I have the minidsp umik-1 microphone and am trying to pick up impact noise from the floor above. Is there simply a playback option of the sounds captured?
Tried to watch. Background music was too obnoxious and distracting. 🙄
The music overlay during a tutorial is not a good idea and made it too distracting for me to finish watching the video.
And its too loud! I had to turn it up to hear him but then i hear too much music
What should be the mic gain and sound cards output level while calibrating soundcard

Why not measure L+R at once since that's what we'll actually be listening to?
Because of interference of conflicting sound waves..

Background music is way too high so makes it harder to understand and follow, especially as English is not the presenter's native language.

Background music was so loud it was annoying.
Does anyone have the number of the handsome guy in the video?
The background noise is killing your video, so hard to focus on what you are saying.
Accent… and he’s clearly reading. It’s better if spoken naturally or from memory
I like your accent yet have no idea where it’s from!
Good video, but.......please stop this crazy music in the background!
Why the distracting music? The content would not be enough to keep our attention, but the dumb music would?

That is useless, it does nothing for the sound, that's not how things work in real life. It all comes down to speaker placement and room acoustics.
I think the video was intended just for analysis for their engineer to give users some suggestions, probably also based on their room photos. Then the final measurement will be done for final correction.
Terrible tutorial. How about tell us why you are doing each step?
