- čas přidán 6. 07. 2024
- An easy to follow tutorial to create the ULTIMATE Audyssey home cinema calibration. Not only it'll eliminate all the suboptimal Audyssey adjustments like steep high frequency roll off, excessive "Dynamic EQ surround speaker boost", inaccurate speaker distance, and inaccurate crossover settings but will also keep "Dynamic EQ" on and benefit from its potential to adjust speaker responses to target level at different volume levels. Only MultEQ Editor app is required, no MultEQ-X necessary.

Total thumbs up OCA!!! I've learned so much by watching and working through your videos. I thought the SOTA walkthrough was good. But this was unbelievable the different that I could both hear and measure. Thank you so much.
Glad to hear it!
These tutorials are brilliant
Thank you.
Thank you again for the wonderful tutorials and amazing help and support!
My pleasure!
You're channel is really exceptional in regards to range and depth of the topics. But also practical and precise. Awesome work and I hope you get a much bigger audience soon. Thanks!
Thanks 👍🙏
WOW !!!!!!!!!!!!!!!!!!! MASSIVE DIFFERENCE !
Two quick notes: In REW export all to text, if you change setting 'Export Text Delimiter' to Tab, the numbers will go directly into Excel columns without having to monkey around with the Excel delimiter. Also, if you adjust distances and levels in the Audyssey MultiEQ app instead of in the receiver web portal, although more cumbersome, they will be saved into the .ady file and you won't lose them if you change between different calibrations. Cheers and thanks for another great tutorial!
Ernie, I'm guessing you mean make the adjustments in the the json editor? There are six decimal places for both trim and distance. For trim, did you try entering something other than half dB increments? Wondering if it will accept levels that aren't .5 or whole dB steps.
@@vincentdemarco6374 no I meant inside the audyssey muiltEQ app on your iPad or other device. When you open your calibration file, one of the submenus is (something like) Speaker Results, inside you’ll find crossovers, distances, and levels. If you input the values here they’ll be saved into your calibration .ady file
It only accepts 0.5dB trim adjustments
Even though I run Dirac, I've learned something from every one of your videos. Thank you!!
Great to hear!
Thanks! Your tutorials and videos are a must for any HT enthusiast. You should be required reading!
Thank you!
Here is my feedback having completed this process. Firstly great learning experience. Going through things a few times makes them easier to follow and dots start connecting. The graphs looking stunning and I was able to follow each step all the way. Then I gave it a listen. My first impression was that the speakers seemed to have come alive a lot more and sounded more immersive but sounded a bit harsh in some instances and the bass seemed weaker to me and also little exaggerated in the upper bass frequencies. I went back and forth with my old settings and the new ones. Since I have a minidsp and a Denon 4700 which has two speaker presets, it was a lot easier to compare. I found the bass sounding better in my old setting so I went back to it but applied some of the learnings from this tutorial to it especially the correction of the impulse responses. That made a big difference and everything sounds better than before. So I ended up with new settings using my old and new and it sounds great.
What was interesting was that the FR between the latest REW and the early access differ. Not sure why but they do. Also for others the controls to see IR distances on IR tab is Ctrl + right mouse key and drag.
Thanks OCA
First of all thank you and congrats on your achievement. REW has been going through an extensive development stage recently and some trace arithmetic basics have been changed although there would not be a difference in the final filters produced.
I have a Denon x3700h andI ended up doing the same as you admittedly, after praising this mothod so much. My results were similar - the mid bass was way too exaggerated and the rest of the speakers sounded like they were crossed over at 200hz, ie; no bass even where the speakers can handle 60hz or even 80hz. I applied the impulse response to all speakers and now my original Audyssey calibration sounds much better. Surprisingly though, the biggest improvement came from turning Loudness Compensation off in the now perfected original calibration. However, after finding the original calibration sounded better, I still learnt so much from this tutorial! I feel like I am now an advanced REW user! Thank you OCA! I hope you can find why the calibration (after following this tutorial) ended up sounding the way it did. I followed it exactly as instructed. I can't wait to try your next tutorial....:)
We love your stuff!
thanks!
Your username is absolutely Perfect Sir. Excellent instructions and great job describing what you are doing and why. Thank you for sharing your knowledge and expertise with us.
You are very welcome
Thank you for all the work you put into this!
Please do a moving microphone technique with Audyssey next.
Sure thing!
Thank you OCA; great video again🙂 i want to try that; in the beginning you mentioned that also MultEQ-X user can apply this method. But how to do this, because the .mqx-files are different and not JSON formated (the Data-section is another format i think)!?
I don't use mqx and not sure what the format of an mqx file is but at the final stage of this method instead of inversion, you can apply REW'S auto EQ to the responses and transfer these filters to multeq-x.
@@ocaudiophile Okay, thank you! But then i think better be careful with statements like this: 'We don’t need ‚MultEQ-X‘, but MultEQ-X users can also easily implement the method', because as it turns out the method can not be used!
@@didi_p7756 There's nothing too wrong with that statement. The method can be implemented for mqx with REW's auto EQ instead of inversion.I have detailed videos on how to use REW's auto-EQ with these receivers.
@@ocaudiophile What do you think about the following workflow for MULTEQ-X users (assuming, as part of the measurement process, MULTEQ-X gets the speaker distances/levels correct)
1. Set REW preferences as prescribed in this video
2. Take all measurements (I.e. three measurements per speaker) with Audyssey enabled how without any Audyssey filters applied (note: MULTEQ-X allows any Audysseyfilters to be disabled via excluding’ ALL measurements in the app
3. Take RMS Average of each set of speaker measurements (I.e. RMS average of the three measurements) Question: Is Vector averaging preferred???
4. Use REW to EQ the response of each speaker’s RMS average
5. Import REW correction/eq filters into MULTEQ-X app
6. Upload to receiver and call it a day!
Great video, loved it. Learning a lot from your videos, I appreciate all the hard work that you've put into this video.
Glad to hear it!
Excellent video with excellent results, I congratulate you for the great work and for the dissemination
Thank you very much!
This was fantastic. Learned a lot from your videos. I'm excited to try them out on my system.
Great to hear!
@@ocaudiophile i have the x3700 denon BUT in the web interface i don't HAVE the setting "LOW frequency effects" !! am i doing something wrong or maybe some models don't have it ?!
update : i had to play a movie with LFE to be able to SEE that setting !
Thanks so much for putting this together!!
My pleasure!
With the instructions of the Dolby Atmos 9.1.6 video I was able to get also a measuring of the Atmos speakers for my 7.1.4 setup on a MacBook Pro, using VLC media player on my Mac. Afterwards quit simple choose the wav file of the sweeps in REW, start measuring and play in VLC the speaker you are needed, every speakers has is own chapter, great work.
Now this evening I can go further with the instructions of this video with my 36 measurements. Great to do this job with a Mac, I am not an experienced windows user.
Glad to hear that. You're one of the very few who could play the Atmos sweeps with a Mac!
Very strange that Mac users too much problems have with REW. And there is more an advantage for a Mac because you need no special drivers. I use Ventura or on another system Sonoma, and the latest REW from the REW-website. On every mac will plays VLC plays and you give the right files and sweeps in you 9.1.6 video, maybe you can these also add to this video.
Furthermore a Mac User must setup his mouse as a secundary mouse. So you can speak more optimistic in your videos for Mac Users!!!
Finally! My system is a new one with you. Especially with my low end Denon 1700h without multieq xt32 the difference is huge in bass management. Thank you so much. Somebody needs to take the method and create a blog post out of it. Because a video sometimes is not the ideal medium while working on such things . Much love ❤❤❤🎉🎉🎉
Thanks
Could you do the blog post pls @Squizzy911
Noted!
i have started writing down from your video the steps to do. but still ongoing. a nice blog post on medium or somewhere with nice tables regarding settings in REW, direct download links, hint blocks and so on would make it much better to understand. it would be also possible to make first a 1:1 tutorial out of it without any deep knowledge background which can be collapsed from special blocks. what you think?
@@ocaudiophile
You've my full support but some techniques have evolved and there are automation scripts in the immersive audio and especially Audyssey ART videos. You might wanna take a look at them as welll.@@Squizzy911
Hello.
First of all, thank you very much for providing the calibration file.
I wanted to make a comment about how to use it:
I was trying to use the Audyssey mic to check the frequency response of my system playing pink noise and using REW's rta. And I believe the calibration file for the Audyssey mic you provided has the positive and negative values inverted.
My system was already calibrated following the avr's built in audyssey setup procedure.
First I measured with no calibration file at all, and I saw a frequency roll off starting at about 7KHz as expected according to what you showed in your other video about the hidden calibration file of the Audyssey mic. Then I loaded your provided calibration file and took another measurement. Instead of getting a flatter response, the frequency roll off starting at 7KHz was stronger. So I opened your calibration file in notepad texteditor, changed all negative values to positive and changed all positive values to negative, and saved with a new name. I loaded this new calibration file into REW, took a new measurement and got an almost flat frequency response. (The system was set to "flat" multeq profile, not "reference").
The calibration file for REW should show the mic output level at each frequency, not the required compensation. That is to say, if the mic's response is rolling off after 7khz, the values in the calibration file after 7khz should be negative.
I hope my comment to be useful for other users who are in the same situation as me: not having a calibration mic and wanting to use the audyssey mic in REW.
(Forgive me if I did something wrong, perhaps there is a way to load the provided file in REW so that it works as it should and I am not aware of it. I found that the file works inverting the values and I wanted to share it. Also forgive me if you or another user already said the same thing about the calibration file before).
I'll check that when I can (I'm away on holiday). It's remotely possible that cal file I've shared is reversed but I hope you're wrong ;)
You were right, it was having the inverse effect on the measurement. I've now updated the calibration file in all videos with the inverted one. Thanks for your attention!
Thanks for your work!
Welcome!
Even just getting the distances and sound levels corrected does a lot to improve the cohearency (intended)
I spoke to John about the inversion with [A] / [B] magnitude division and it is working correctly. What threw me off was that the calculation in REW displays as the differences on a 0db line. I was expecting it to visually invert the response. However, If you export an inversion and pick an area that looks off in REW. For me its was 16K. Look at the difference in the measure response vs the target curve. Mine was -2.5db in REW. This means that the inversion should be +2.5db and in the text file it was. The biggest thing is the way REW is displaying the correction. It only displays it as the differences on the 0db SPL graph. I had to get my head around this. In the end, A / B magnitude division does work as intended, and the 0db line becomes the target curve.
Hey man. I finally got around to giving this a shot.
My results were pretty good. Only thing I changed was I made the target curve give me way more bass (about 10db to match the uncorrected curve of my speakers) and I made Audyssey not do any correction after 10khz because the boost of highs was way too fatiguing in my room.
Using this method has made my home theater sound like a real theater. It doesn't sound like speakers, it sounds like sound. No it's not perfect but nothing will ever be perfect in audio. Thanks for the video!
Cheers!
@@ocaudiophile Yeah man you are doing some really good work. Do you take your measurements with sofa cushions on or off? I think the high end boost might be because I measured with my sofa cushions on but I saw another video from HD MOVIE SOURCE saying to measure with the cushions off.
@chadkirk925 The differences are too small to measure precisely. I'd rather put effort to place the mic tip where your ears will exactly be during measurements and leave the room exactly as it will be during film watching for better results.
@@ocaudiophile thanks. That is my thought process too.
channel name checks out ! 😅
Im lost in the first five minutes. Perhaps this is for the advanced users. Looks amazing though, wish i had the patience to do this. 🎉🎉
Thank You for doing this.
Cheers.
@@ocaudiophile I need to take some time to learn. I’ve just got my new X4800H. I also need to buy the iOS app. I think this tutorial is great, and it's one of the best I've seen so far. I really hope I can achieve great sounds like you.
@@netster Multeq editor app is the cheapest best audio upgrade ;)
Even better video is launching soon....
@@ocaudiophile ok. Thank You! Keeps up the good work and I’m your new fan. Really appreciate what you doing here. 🫡
Just finished the calibration. What a difference!!!! How can I offer you a coffee? Where is the donate button, I need it now 🤣
Can you explain the difference from Audyssey (refined post calibration) to this method? I am starting this process soon...
This one uses Audyssey and dynamic EQ so it has better low volume equalisation. It can also be more accurate compared to manual GEQ bands
Thanks!
Would love to see a video on using RTA!
Coming soon!
Awesome video!! I'm just curious as to what your thoughts are on starting with the timing reference speaker (eg. center channel) set to something different than actual. For example, if my center channel's actual distance from the listening position is 2.74 m but I set it to say 2.34 m, will everything still sound ok as long as I time align the rest of the speakers to that speaker?
Yes, surround effects will be accurate. It only has an effect on the size of the sound bubble. Btw if your actual distance is 2.74m, you need to enter 2.40m in the receiver distance setting anyway due to speed of sound being taken as 300m/s in most models.
N1 ❤️ Thanks also to Zahraoui for the nice script! You can use it with simple command on windows CMD 💯
Thank you! I've waited a long time for someone to do a tutorial manually tuning HT/atmos speakers. Bless you! .....Initially, I tested the sweep files on all my speakers and determined that two of my Atmos speaker's high frequencies dropped precipitously around 1000Hz. Thank you for the files to test them. In the Denon AVR-X4700H Low Frequency Effects are displayed when
"This item can be selected when a Dolby Digital or DTS signal or DVD-Audio is played." I did not set this initially and continued with the tutorial with 7.1. Should I have played a DTS movie and then set this at the beginning? What do I set the Reference Level Offset given I did not set Low Frequency Effects?
Thank you for bringing my Home Theater to life. My 7.1 sounds so good I wonder whether I needed Atmos.
I suggest you use Denon's web interface to change its settings. WHen you start palying any of the sweep files with Windows Media Player, all these settings will sho up in the web interface and you can adjust them. RLO has nothing to do with LFE. LFE -10dB offset is just a temporary setting to see the sub response where it really is relative to other speakers. RLO is a setting which adjusts the strength of DYnamic EQ.
amazing tutorial. many thanks! my 2 subs on mini-dsp seem to arrive much later than receiver can set (+6.8m to center). in this case would I just set to maximum available distance? or is there anything smarter I can do?
Million dollar question ;) There's not much you can do to compensate for the time delay introduced by MiniDSP in the reciever.
*Play around with bass sync setting if you've a Denon (Marantz don't have it), that might add some delay compensation.
*You can switch to IIR filters (biquads) in MiniDSP if you are using FIR filters (taps) which introduce delays to the system.
*And last resort: You can align subwoofer's previous impulse peak instead of the highest peak to the center channel
Great video, while thinking this through I wonder how you adapt for custom curve in the bass region. Will you just create a target which will not be just "flat" harman curve, but will rather have a little bassboost around 20-100hz?
I remember the harman curve you used in your "Audyssey hacks for epic Dolby Atmos" Video had a slightly different harman curve with a little bass boost. So what is the correct harman curve, or to rephrase it, did you edit the harman curve in the former Video more towards your taste in the bass region?
The one in the video is standard, only with extended frequency range. The bass boost will depend on the windowing and to some extent smoothing used on the response. The method in the video yields a very satisfactory bass when applied.
Wow, this makes a ton of difference! The clarity in the sound is much improved, thank you!
However, I think the sound after adjustment lacks a bit of 'punch' to it. Is there something I should be doing different or maybe go for another target curve? Is there one you can recommend to try in that case?
Keep up the good work 🙌
Increase the subwoofer volume 1-2dB maybe?
@@ocaudiophile thank you for the quick response! I believe it is more than just the bass that is lacking. The sound feels flat sort of ...
Audyssey ART video method is more advanced.
@@ocaudiophilethank you sir, I will try that 👍 massive thanks for all your effort
Thank you very much for taking the time to do this. My receiver only has multeq (not 32 or xt) so I was intrigued by this video. Unfortunately, after completing the process, I got no frequency response below 120hz whatsoever. My sub was set at -12db to hit the target curve and even after boosting it to +12db in the audyssey settings and turning the gain on my amp up an additional 30%(maxed out) there was maybe 1-2mm of travel from my subwoofer and no bass from my bookshelves. I intend to redo the process from creating new corrections forward, potentially with another curve, but I am curious if maybe multeq does not have the resolution that multeqxt32 has and as a result, some numbers may not transfer to my avr. For instance, when adding the 241 points to the custom “target curve points”, could audyssey be ignoring 100 of them or something to this nature because it is the lesser audyssey version?
I don't think number of custom target curve points is a problem for the type of MultEQ as long as the app accepts them (I think the limit is somewhere near 65,000 points). However, MultEQ uses significantly less number of FIR taps compared to XT32 while generating FIR filters which will effect LOW BASS correction very much. In other words, Audyssey may not be able to correct properly to the target curve it's pointed at especially below 100Hz.
@@ocaudiophile Quite appreciative that you took the time to reply. I hope i dont seem as though i am asking for help diagnosing my own issues here. I am simply trying to contribute issues i am having in the event someone else runs into these problems. I am now concerned that the measurements i took with REW were being influenced by the existing Audyssey profile's corrections ( i had a traditional audyssey correction applied prior to starting this guide). I will start from scratch with a factory reset and report back. Once again, thank you.
Thank you so much for these great tutorial videos. One thing I’m a bit confused about is that information seems to overlap in your videos and I’m not clear if there’s a particular order to watch them in. If I do the Supreme Audyssey Calibration for example, are there other tutorials I should follow next?
What video would you say is best to start at and follow for Audyssey (Home Theatre focus)?
Thanks again!!!
There are improvements in the techniques in the most recent videos mostly because REW has been continiously improving. I think, you can get some additional tips from "Audyssey for Dolby Atmos music" video after the "Supreme Audyssey video"
Danke!
Many thanks, you didn't need to!
So i finished the calibration and it all sounds excellent. Thanks
Subwoofer is still not perfect and is difficult to integrate because i have a pretty big peak around 25hz and my line is nowhere near as straight as yours
Hmm maybe i messed up the subwoofer measurements / eq?
ill try doing the sub again later
I might just need a second sub
And the crossovers are surprising..
Front and surround back 110hz looks the best, center and side surrounds 60hz looks the best
Maybe it has to do with my room
(My fronts are Polk R200 bookshelfs, should go down lower just fine)
Subwoofer response is the hardest one to get right and unfortunately the most dominant on good overall sound. DEQ changing bass boost for every volume level doesn't help either. Still, Audyssey should be able to kill that boost at 25Hz (unless you have XT rather XT32) and remember that after heavy EQ is applied sub's impulse peak might move a little bit and may need distance readjustment.
You can try and XO every speaker at their specs (ie -3dB roll off frequencies). If your speaker pairs are relatively symmetric, this might give even better results.
@@ocaudiophile yeah I saw the peak and thought maybe I didn't perform the room correction step properly on the sub
Gonna redo it 🙂
Hey OCA, how have you been? I've noticed that A over B magnitude division is overcorrecting on the EQs I'm doing. Do you have any idea why? I've seen that treble sometimes needs an increase of 1.5db, but the A over B is increasing by more. Like 2db. What could be causing higher numbers than needed? Is it also taking into account reflections in the sweep? Can I remove that? Or just measure with an RTA?
I guess these deviations are caused by the complicated maths behind the division operation between two FFT's especially when it's not over a flat line but a target curve. The beginning and the end needs some mathematical gizmo to be handled. I use direct 1/A inversion lately over a flat line for that very reason.
I'm enjoying going through the process! However, with my Denon x3800 I've seen a few issues after uploading the .ady file back to the receiver and trying to make your changes in the "Cheating Audessey" stage:
1. When I used MultiEQ to create the Original file it knew I had Top speakers... but after uploading the new one the web interface listed them as Front and Rear Height speakers. I changed them to Top Front and Rear under Speakers--Speakers Layout, but wanted to make sure you didn't think there was some other issue.
2. After uploading the Default.ady, in the Distances it did not default the Top speakers to 0.04 like the others. It had a pretty high number on them (like 6 or 8 meters). I manually changed them to 0.04
3. Similarly, my Subwoofer 1 "Level" was -2, whereas all the rest were at 0.
4. When I go to Audio - Sound Parameter, it does not show the same options. It only offers Effect Level, Room Size and Speaker Select... none of which your screen has. Most concerning for me is I don't see where to lower the LFE by -10.
Is it OK that I had to manually update my items 1-3 or did something go wrong when I made by "Default" file?
What are your thoughts on #4? If the Denon interface is different, how do I handle the FLE adjustment?
Lastly, when I was editing the .ady file, it showed 13 channels (7.2.4) as 0-12... but channel #12 (I'm assuming Sub 2) did not have any recorded Response Data for me to be able to edit. Is that how it should be?
Thanks in advance!!!
1. When using MultEQ Editor app (or the receiver's own setup menu) for calibration, user needs to tell the app the correct speaker configuration with amp assign. The method will not change that configuration. I haven't tried manually changing them in the AVR after sending the ady file to the receiver so I am not sure but I wouldn't risk it. I guess it's safer to run a new calibration with the MultEQ editor app with the correct configuration. You can stop it after only 3 measurements.
2. That could also be related to manual speaker configuration change.
3. Levels always came up 0 initially in my tests but I have seen odd volume adjustments in the later stages after re-sending calibrated ady files. Manually correcting them is fine.
4. x3800h has LFE setting in the menu according to this:
manuals.denon.com/AVCX3800H/EU/EN/GFNFSYvdfworfs.php#OKNRMLxabcenvo
You might need to send an LFE signal to the AVR to bring it out.
@@ocaudiophile Thanks for your quick response. I started from a new file. It still changed it to Heights instead of Top.... but when I made the change everything else worked properly, so I'm good with that stage!
Now 4 questions/issues with Measuring:
1. I'm now having an issue with the .mp4 files not playing properly. I checked and my AVR is showing as the default audio device. I do have the Windows Sound settings set to Atmos and I can play the Dolby Test Tones perfectly fine and the Denon shows Atmos. When I play the .mp4 files it shows Multi-channel-in instead of Atmos... and plays all the recordings as Stereo.
2. Should the volume on the laptop be up to 100 for these tests? At first the volume was very low until I did that. Just want to make sure that's right.
3. I normally watch movies around -20db. When I ran Left and Right tests at that level I received an error message that the signal was not high enough. I then raised it to -10 and it seems to work, although that is higher than I normally play it.
4. Even when at -10, I receive an error message that the signal to noise ratio is too low. I've even turned off the air conditioning when doing the test and still get the message. The room is pretty quiet except for the sound of my laptop's fan. Is there something I need to correct, or do I just tell it to stop giving me that message?
Thanks again!
1. Windows sound settings should NOT be set to Atmos, setting to "Stereo" should work fine(AVR set as default playback player, L&R set to Large, all enhancements disabled, give exclusive control to other apps, etc. all ticked, 16 or 24 bit but definetely 48000Hz sampling rate selected). Windows Media Player at default settings, reinstall it if need be. The AVR should be in Movie/Multch-in or stereo mode. Try until you see the AVR switching to Atmos when you double click and play any of the mp4 files with WMP (you don't need to play them through REW).
2. All volumes should be at 100
3. Sounds like you microphone input level is too low, REW should normally easily measure levels as low as -40dB. Check your microphone input levels in Windows sound settings.
4. You may want to switch to Java EXCL drivers instead of ASIO, usually they're easier to set up.
My JSON edited file says "Is either corrupted or not in correct format" when i try to open it in MultEQ.....I only have Audyssey MultEQ and not XT32 (Denon 2800 receiver) . Is that the case? EDIT : now is working, i was probably copied too much from excel table
I am not sure if anyone has asked this question before: with this method you calibrate with DEQ enabled at the MV level that you typically listen, but what happens to the response if you don't listen at the MV level where you calibrated everything? I know DEQ boosts its effects the lower you go in volume, but does it maintain the same level of (for a lack of a better word) neutrality throughout the response?
İt might not be optimal but deq defo helps at the lower volumes
Hello and thank you for sharing your knowledge and work. One question so far: You changed low frequency effects to -10db due to Atmos db bosst. Does this apply to a standard 5.1 sytem like I have too or should I leave this option untouched ? Thanks again
Yes and yes but best way to find out to listen the result yourself
Hello and big thank you for the great tutorial.
After following the steps I finally hear my Dolby Enabled Speakers reflecting from the sealing. The sound in movies is impressive, compared to the sound the system does with just Audyssey. I don't know what the people at Audyssey tought when inventing the correction curves for the Atmos speakers, but it is not working well. The Atmos effect with my 4 Dolby Enabled Speakers is now, implementing your method, great. I now understand why people think, the "bouncing" speakers are crap. Audyssey cuts them in such a way they really sound as crap.
One thing, that makes me think that I might have made a mistake at some point through the tutorial is the fact, I still have to adjust to the high pitch of the sound. With Audyssey it is somehow warmer...And my correction curve in MultyEQ app after finishing your method looks like a zigzag with multiple zigzags... Don't know if this should be the outcome...If you can share your MultyEQ curve after implementing your method I would be glad to compare to main, just to be sure, main is OK...I cannot actually call my outcome a "curve" :)
Big Thanks for your time and the comprehensive why of taking me trough the tutorial.
Don't worry, it's gotta be a zigzag. The method uses Audyssey curves to apply the actual correction. The zigzags you see are the equalization applied to each speaker. I didn't undertstand what you mean by adjusting high pitch of the sound?
@@ocaudiophile If I compare the sound of the outcome now with the sound of audyssey, then I feel like the sound is much more "sharper" (almost scratching my ears form time to time), less "warm", and voices come out "thinner", thinner perhaps because of the presence of the high frequencies, which were not there before...For me now, it is as if I have different speakers, and I have to get comfortable with them first...
When I look for the crossovers with your method, my crossover for the Dolby Enabled Bouncy Speakers comes out at 90 Hz. What would you recommend me to do with this relatively low frequency. Should I crossover them higher like 150 hz? Somewhere in your video you talked about high speakers and crossing them also at 80 hz, to avoid hearing the top sound out from the subwoofer on the ground. Or perhaps I misunderstood something...Of course my dolby enabled speakers are not high speakers...Perhaps thatswhy I should choose the higher crossover?
Front speakers have the option for 60 hz and 90 hz
Center comes out on 40 hz or 80 hz
Surround at 60 hz , 90 hz or 120 hz
What frequency would you choose in my place?
Now I am mrunning Front @ 90 hz; Center @ 80 hz; Surround @ 90; Dolby Enabled Modules @ 150 hz
Thank you in advance!
@@miroslavpetkov9895 Do you have one or two subs and how are they connected(ie MiniDSP or directly to the receiver)?
@@ocaudiophile I have only one Sub (SVS SB 2000 the older version, not the pro version) at the present moment. My room is small 6,50 m to 5,05 m to 2,47 m. My speakers are Heco The New Statement as front, Heco Celan GT 42 as center, Heco Revolution 3 as surround, Heco AM 200 as Dolby enabled speakers in a 5.1.4 configuration. All of this is connected directly to my AV-Receiver Marantz SR 8012.
Appreciating your help.
Thanks.
@@miroslavpetkov9895 Ok, if you don't use MiniDSP for your sub you can time align the sub properly with the receiver's distance settings. MiniDSP causes extra processing delays which makes this very difficult. When the sub is time aligned, it will be very easy to see where the crossover frequencies should be. For the treble problem you're having, suggest you follow the method in the Dolby Atmos Music video. I used Dolby's own target curve there which is much softer at the high frequencies.
First, thank you very much for this guide. I am eager to try this for myself.
I have one questions: can I do this process without using DEQ? Different movies are mixed differently and for compressed audio I have to turn up the volume which would mess up DEQ, right?
And dont we have to SPL all speakers to about 75db or so if not using DEQ?
And can I measure and EQ two subs with REW and MiniDSP before wallthrough this guide? Or is it better to use your Sub Alignment and cross corelation video?
You should measure and create filters for your system at the volume you like to listen to it. If you take these measurements with DEQ on, DEQ will then adjust the calibration for louder or dimmer volumes on the go so it's useful for the problem you mention. It has some odd adjustments for surround and height speakers, etc. but still, it's better than nothing.
If you are using multiple subs with a MiniDSP, it's better to time align the subs first using the sub alignment video and dial in the delay settings in MiniDSP.
Thanks
Many thanks!
@@ocaudiophile
Only fair with a the help you have given me!
Thank you for the excellent video. In the narration you state midrange compensation should be off, but in the JSON editor it shows midrange compensation box as checked (true). Should the box be checked or unchecked? Thank you
Uncheck it for every channel except for the subwoofer channel where it's irrelavant but may help reduce noise in the upper frequencies. The much newer Audyssey ART video is easier to implement btw.
2nd question. Do you know what key and mouse strokes are used on a mac to determine the speaker distances on the impulse graph in overlays?
I don't have a Mac but should be ⌘ key instead of CTRL plus mouse right click?
Configure the mouse button as "Secondary Button," hold down CTRL and the button and click and drag. Intuitively obvious, no? 🙂
Tak!
First ever DKK asset I have in my life ;)
@@ocaudiophile well..we are almost neighbors so :D
@@_shogun_gaming_ 😅
Another great video, thanks again.
I can't seem to get audio out of my front height speakers using any of the "Atmos sweeps" files, any ideas?
I have double checked all settings for my receiver in windows, made it default device, no enhancements, etc
When using the dolby-test_tones_9_1_6 file it does match correctly for all speakers so I'm a bit confused.
It's a 5.2.2 system and a denon x4400H (should it be in "Multi Ch in" mode?)
Some things to try: Select "Movie/Stereo" or "Movie/Mult ch in" in the receiver, reinstall Windows Media Player, with default settings, Check sample rates to be all at 48kHz in Windows sound settings, Denon should be the default player, if all else fails try with VLC media player with Windows direct sound and HDMI bypass option active.
very impressive, thank you very much, another step up to the moon :) by the way, for the LFE cut off at 120Hz, it is not related to setting into the AVR (LPF for LFE) ? and an other thing for the filter curve generation, MultEQ-X app offer the possibity to import REW fiters, it say "EQ is limited to 10hz to 20khz, -10db to +10db, and Q 0.1 to 10" do we have to make sure that the generated filter curve is not going above that ? and thinking if it is better to create a filter curve from the EQ by using a generic filter that match this parameters ?
No, it's not effected by the LFE cut off in the receiver (that was also my first thought and I tried increasing it to 250, no change in response!)
You can't replicate these inverted responses accurately with EQ but you don't need to. In REW EQ filter types, choose "Generic" as manufacturer and "Configurable PEQ" as model. Then you can set all these limits for MultEQ-X you've mentioned in the configuration and REW's auto-EQ will "match response to target" within these parameters. Then you can export them to MultEQ-X. Don't forget to keep the target level same for all speakers after initially calculating it as explained in the method.
@@ocaudiophile one little tip about REW zooming, it focus on the cross in the graph, so make sure to clic on the impulse start before cliquing on zoom+. I say that because it hapen to me and now I figured out it helps
@@armagedon2B noted thanks!
Hi OCA. It is the last thing you remind us to do, but just wanted to double check. Do we change the Low Freq Effect back to 0db after we determine the crossover frequencies, or at some point before that?
That will not have any effect on the sound for sub and speaker crossover. LFE volume only changes special effects recorded for the sub channel only.
I have done the process twice on my SR6015. The second time after calibrating Subs with Mini DSP and treating the Room with some Absorption/Diffusion. However this time my Polk RTi A7 sound very bright? Since the Audyssey App Room Correction Results and Curve Editor graphs are kind of unique after calibrating, I am not sure If I could/should edit them to reduce the brightness. Any recommendations on how to adjust the sound of the Mid Brilliance frequencies w/o going through the trace arithmetic speaker correction process?
You can change dynamic EQ strength form 0 to 5, 10 or 15. Turning "Cinema EQ" on will also dim the HF a bit.
Thanks again for your work! Really enjoy how my system is sounding now on my Denon x4400.
If I upgrade to an x6700, can I just import my saved profile from my old x4400 to the new x6700? Or do I re-do calibration to the new receiver?
You can manually edit the ady files side by side and copy/paste objects in json online editor but 6700 is a different beast and probably has different crossover rolloffs etc. I'd re-do the measurememts.
Excellent tutorial. I am in the process of doing the whole thing. Since i have 5.2.4 system, i have 2 questions; how i deal with th le two subwoofers? How indeal with the 4 atmos? Finally it would be nice to show a full frequency response after younadjusted the crossover and see how the suns integrate with the mains
Thanks. If you don't have a minidsp, to manage two subs, remember that Audyssey has only one correction filter for subs. It time and volume aligns each sub and then corrects the sum of the two subs as one.
Hi OCA -Thanks for all your videos, but this one I can't wait to get started on!
2 questions that might be very stupid so please forgive me
I have the Marantz SR-6012 - it does have the Audyssey app but I just can't get the web interface to work. I get Error 403 - Forbidden/Access forbidden.
1) should I have the option use the web interface at all?
If not I might just have to use setup via the remote control - will work but takes much longer
2) but when I access the setup from the remote control - under audio/surround parameter I don't have "low frequency effects" at all
Will that give me problems?
Kind regards
I had 6011 and now have 6014 and both have Web access, maybe network control is off in your receiver menu setup.
Certain setup parameters only come out when there's an audio signal being fed. Play an atmos track and try reaching that setup menu item.
This is really great. I appreciate you sharing your knowledge!! Quick question - do you recommend doing this for 2.1 channel music listening? I have a 5.1 system with Audyssey default calibration. I disabled the mid range compensation using the app because that sounds better to me. I use it for movies. But for music I switch to L/R Bypass and 2.1 stereo mode because that sounds better to me. It comes close to Pure Direct on the Marantz 5015 receiver but a bit better due to the SVS sub filling in. I would love to improve the music experience but I need to set up REW and buy the umik-1 microphone
You can use Audyssey's microphone and REW is free. I extracted the calibration file for it (check my latest video's description link) and its results are quite satisfactory and timing is better than a USB mic. With proper sub-main time alignment and graphic EQ, you can get nice stereo sound.
Thanks for the idea@@ocaudiophile. Unfortunately I cannot connect the Audyssey mic to my Macbook Pro as it does not have a mic input. Neither does my Windows Thinkpad for that matter. I will order the umik-1 in a few days. So you do recommend doing a good calibration for stereo listening
Especially if you have easy to drive mains, you could get good results. With higher end stereo speakers, these AVRs are not powerful enough in general. Good speaker placement and descent DSP always prevails though.
@@ocaudiophile I have B&W 683 towers rated for 89dB sensitivity in the front. Marantz 5015 driving them. I will get external amp later. 80% music 20% movies. I am happy with music just want to see how it can get better

You should Switch the “Network Control” setting to “Always On" in the receiver menu. You can leave the sound profile at stereo, it will change automatically.
@@ocaudiophile Thanks :) Network Control was already ON but I saw on forums that Web Control for SR7012 is no longer available (only for SR7015), I have to rollback the FW, but no idea how to hack the AVR FW for this
So for stereo I leave Movie Stereo or Pure Stereo ?
@@Mitholman73 I don't change this setting at all, it automatically switches depending on the incoming signal. Stay away from pure direct modes as they bypass the subwoofer and Audyssey settings.
Hello. I did the JSON editing part. I opened it back in JSON to make sure it was showing the new values. Still after importing it into my AVR, I checked the levels and distances and they were not as expected.
Any idea what could be wrong?
Thanks!!
Are you on MultEQ-XT or XT32?
@@ocaudiophile XT32
Then it should work fine. Some XT users encountered similar problems. Have you converted responses of ALL speakers including the subwoofer to perfect (1,0,0,0....)?
@@ocaudiophile Yes I checked a few times and all of them are showing the correct numbers including the subwoofer. Bummer :/
I am using the latest beta release of REW (5.20.14 for mac), and have run into two problems. The first is that when I try to determine the distance from the cross-correlated channels, my sub distance is calculated as significantly further away than the actual measured distance. I should note that I ran the measurement with the sub phase angle at 270 degrees. Could that be the cause?
Subwoofer impulse peaks are very often too far to be compensated by the distance limits in the receivers and this is normal. It's due to the time delays introduced by the filters in the sub (or by MiniDSP if you're using one). You can try aligning its firts peak with the acoustic reference speaker instead.
Regarding the "Speed of sound" value setting/correction. What is your reference when determining whether your AVR is using 300 or 343 m/s? Do you measure it with a tape/ laser, or do you measure with both Audyssey mic and Umik at the same position and compare?
It's caused by the AVR so it's mic independent. I measure with laser just one of my speakers and compare with Audyysry's own finding. The difference is usually too large and even with tape measure you would understand your receiver is using 300m/s. Btw, after a recent update my Marantz sr6015 now uses 343m/s. Many other models have been fixed but not all.
@@ocaudiophile Thanks! My Denon X4500H also received a couple of updates over summer, fingers crossed.
How would you do this with multiple subs? I can obviously measure both of them separately and together but can the individual curves be uploaded for each specific sub for example? so that the best can be achieved by each sub.
czcams.com/video/ga2eOwJRtXo/video.html
New to REW,
Say you ran Audyssey and now starting to use REW and going to follow this video. What do you set the crossovers at to start?
All speakers are set to "Large" when you send a perfect speaker response .ady file to the AVR so no crossover at the start.
New to the channel and really like it.
What’s the best calibration process if you don’t have a laptop? I have Audy MultEQ XT32 on the Denon and the MultiEQ app, but no laptop.
It doesn't need to be a laptop but you need a computer to manipulate the ady file produced by MultEQ Editor
@@ocaudiophile Thank you. We need a cloud based version! Keep up the good work. Subscribed!
Thanks for that great tutorial. In a previous video you also used parametric eq filters (for yamaha), but i am using multeqx on my denon. Can i also use paraeqs with this tutorial and do i meed the hassle with python and excel, when i can use multeqx?
Denon does not have parametric EQ, it has only a graphic eq with fixed frequency bands but of course you can use that insetad of Audyssey. I have one preset with Audyssey and one preset with GEQ in my Marantz set up.
@@ocaudiophile thanks for the answer. Since multeqx support the usage of parametrics eq i will try my luck. You can also apply them without measuring your speaker wirh audyssey, thats what i want to try with rew then according to yout videos.
Just wondering (again) if its normal that my height speakers needs alot of boost to get even with the rest? ofcourse they are abit further away, but still, my C for example is at -5 but height is +5-6... reason i ask is a read somewhere that putting extra db+ on your speakers isnt a good thing for them long term, but no idea if its true or not..
That's normal, mine are +8. Smaller sattelites need more volume to level with the rest of the speakers. It's harmless.
I have a lip sync issue, is this related to anything I may have done incorrectly? My center channel peak impulse was inverted when trying to time align
You can change the polarity of your center speaker. Ignore if Audyssey auto calibration gives you a reverse polarity warning. Ideally, all impulse peaks should point at the same direction (including the subwoofer). If you turn on "Auto lip-sync" in the receiever, it should take care of most lipsync problems btw.
Have you used MSO to align multiple subs? Do you align your subs first in minidsp then do everything in this video?
I don't use MSO because I have only two subs which I can phase align with REW Alignment tool but I would if I had more subs. And yes I do align them and set them up in MiniDSP first.
Hey, thanks for this great tutorial. I noticed that the amplitudes of FL and FR are exactly opposite to the rest of the speakers. Do I need to change the plugs on my speakers? Is this the fabled wrong phase?
I use a down fire subwoofer which according to impulse response should have a distance of 11 meters and the curve looks more like a mountain without a plane like yours. Is the sub wrong or should I try it in frontfire? I can not set 11 meters distance in the receiver nor do I know later how I want to set the level with the curve of the subwoofer it looks like a mountain with a peak as I said. Thanks in advance for your help
Compare the overlays/phase graphs of front speakers inverting polarity of one of them (REW can do that with one click) and phases match better inverted, then do so physically. It's uncommon front speakers having opposite impulse peak direction but not impossible.
Thanks for your answer. I have switched the cables and now every amplitude shows in same direction. Or is it ok when some speakers have inverted amplitudes? I thought this causes bass problems
I did my original calibration using your process and the test signals built into REW: the results were significantly better than Audyssey, and I thank you for that. Now I want to experiment with your 'Atmos Sweeps' files. When I use the signals that are built into REW, I can specify which speaker I want to use as the reference. How does REW sync the test signals when they come from your individual .mp4 files? In other words, what does REW put at t=0 for each speaker signal?
Atmos sweeps are identical to REW sweeps in terms of timing. You can adjust speaker distances same as others
When I select 'from file' in the measurement pane, the option to select a specific channel as the timing reference goes away.
Is there a way to do name a specific channel as the reference when using your files?
@@ronaldippolito6785 They all use center channel as acoustic reference but REW will adjust for that if you're using a different one as long as you don't change it during measurements including all non-"from file"measurments.
Hello, could you please tell me the order of videos i should follow. For example, do i first do the sub alignment qnd house curve before doing the steps in this video? Or do this then align the subs?
Align the subs first and treat them as one and correct their summed response.
So, in the preferences section of REW, keep ‘decimate IR’ ticked? I thought you had previously advised against such?
Decimate IR should ideally be unticked but it has no effect on this correction method. I just tried to keep it as simple as possible.
Got it. Thanks!
@@ocaudiophile I get it. Definitely understand your desire to only focus on the things that matter.
Hello, OCA. Thank you for all you do. I am really enjoying your channel and learning a ton. I have a question and hoping you could answer it... If my peak impulse on both of my fronts is >0 and my peak impulse for my center is
oh, btw, I have my fronts connected to a 2 channel amplifier and my Center channel and surrounds connected to a 5 channel amplifier. The Center peak peak impulse is 0. i'm just curious if that is an indication that the speaker is hooked up incorrectly.
It doesn't necessarrily mean that but if they are the same speaker brands it's quite likely. Best way is to compare Overlays/phase response of center with the rest of the speakers across the frequency bands by inverting polarity of the center speaker. You can do that from within REW without changing wires and decide which polarity is correct.
With external amps polarity switching is very common.
Yet another rookie question : whats more important, setting your avr to - 24.5 and check levels are around 70-71 for C (with 0 db all across the board in the avr volumes) or, raising the level on your avr to hit 75 db in check levels?
There shouldn't be any. A step is skipped in the video by mistake. It's explained in the description area.
@@ocaudiophile i switched my avr to 0-98 db scale, and at volume 55 its pretty close to 75 actually ;)

abit off topic but not really :) do you ever use the aligment tool? i read alot about it thru the different forums, that its the "correct" way to set your sub "distance" right etc..
I've a video on subwoofer alignment which uses that
Thanks you so much for sharing your knowledge and enthusiasm with other fans of home cinema systems. I will follow this tutorial and aply it in my Denon receiver. In a first phase I will use the original Audyssey microphone, with the calibration that you shared for REW, to evaluate the results. Later I'm thinking ordering a calibrated microphone, but I'm undecided between the UMIK-1 and the UMIK-2. If budget is not an issue, do you consider the UMIK-2 a better option? If yes, why? Thank you very much and continue the awsome work :)
For AVR calibration Umik-1 is really good enough. If you will dive into advanced digital room correction for stereo hifi in the future, I would rather go for an audio interface and a XLR analog microphone. XLR mics have better timing accuracy. Basic sets will cost less than an Umik--2.
Much appreciated for your answer. I'm only in the Home Theater so, taking into account your comments, the UMIK-1 is good enough for my best use. 😉
I followed the first steps but I got stuck in the PC multichannel output. I was not able to do it in my NUC PC with a Realtek audio drive. Any tips?
@@miguelmedinaramos You can choose between ASIO and Java EXCL drivers in REW. For ASIO, you'll need to install ASIO4All and you don't need to bother with Windows sound settings. All settings can be done from ASIO control panel. If you use Java EXCL drivers, Windows default player should be your AVR and the AVR should be in Movie/MultCh-in mode.
Just to give feedback it was quite simple after I use another PC. My PC is outdated (hardware and software) thus the ASIO4ALL did not worked. I will update my PC and surely will work. ;)
At 12:00, you describe how to set up the room curve. The settings you give will yield A Harman room curve.
To generate that Harman curve, is REW changing the test tone output to be higher at 20 Hz, then decreasing the amplitude all the way out to 20,000 Hz?
No, REW's sweep volume is fixed throughout the frequency band. Most speakers naturally have this slope towards the high frequencies
I don't understand, yet. When I look at your response curves, they look like they drop about 7 dB from 20-20,000 Hz. I guessed that the sweep amplitude decreased at the slope you entered in the equalizer preference panel, and level matching is how the response fit the Harman curve.
If the sweep volume is constant through that range, what drives the response to a constant negative slope?
@@ronaldippolito6785 The low frequencies are always boosted by the room walls and there's also usually additional downward slope intentionally given by the manufacturers if you check their anechoic response because we tend to hear these frequencies higher than they actually are so in fact it's flat to our ears.
I'm stuck at importing txt file into Excel "Audyssey Curve editor". Somehow I have commas instead of dots in dB values..And then when I apply "convert text to colums" with Space ticked, the excel erases commas in dB values or example : from -3,965 i get -3965, and this of course don't work later in JSON. EDIT : I found the solution - when export I needed to tick "Use computer's number format"
Hi d1234
I have the same issue as you have (or had) - but you have found a solution. Unfortunately I still have the problem.
When I have the raw text in Notepad it wil say ex -3.965 but as soon as I paste it into Excel it converts to -3,965
so comma instead of dot - and I can't get JSON to accept this format. Have you succeded in that d1234?
I can't for the life of me find out what the heck I'm doing wrong?!
Still hopeful regards
It's related to your Windows regional settings which effect use of . or , for decimals. You can fix that either through Windows settings or by simply editing the formula in XL.
Fantastic tutorial! Can't wait to have a crack at this over the weekend. One question (and I know you're not a Mac guy OCA, but maybe someone else can help?): I believe what ASIO is only necessary because the Windows audio stack has so much latency. I've read that the Mac audio drivers are significantly superior - better even than ASIO4ALL, so on a Mac I can just use Java and all is good?
Yes and especially with the new Java EXCLusive drivers available in REW early access version.
@@ocaudiophile Thank you!
Can you share the channel order by which we have to paste the numbers from Excel to Json ? My Top front Right and Top rear Right response curve seems far deviated from the target curve. So I had this doubt.
0 - FL
1 - C
2 - FR
Like this, can you share the correct order?
Your assumption is correct. If you follow the much newer Audyssey ART video tutorial, there're automation scripts which ease these tasks quite a bit.
Got it going! Long story short, I could not get REW to play multi-channel and only Java works on my laptop. Anyway, your mp4 files did great!! I was able to measure all speakers. HUGE help.
REW was saying the volume was too low so I took measurements of the FL and adjusted the master volume until the graph shows a peak at about 75db. I left the volume there and took my 30 measurements. See any issue with that??
Nice to hear
Question: Is there anything different about some of the key shortcuts between Excel and Numbers? I am on Mac, and I never really use Excel/Numbers, so I have no idea what key shortcuts you're using to select the data in the columns in the curve editor to copy into the JSON editor. For example, there's no "Data" option in the top menu within Numbers.
Unfortunately I have zero experience with Macs but if you export from REW with "tab" as delimiter rather than "space", you will not need to "text to clumns" the data in Excel.
@@ocaudiophile As I've fumbled around the software this afternoon, I discovered that Numbers does everything automatically without doing anything, which is nice. What I would be more interested to know are the keys you're pressing to only select the pertinent data in the Excel file to paste into the JSON editor (i.e. only the data listed in between the square brackets) - there's probably an identical/equivalent on Mac. Also, I ran into something I don't know how to resolve. If I create a .txt file with correction data that includes anything below 20Hz (because my subwoofer extends below 20Hz), and I paste that information, the data in the "Copy to .ady" column gets cut off, and doesn't include everything. For example: in REW, I set the custom range to 10Hz - 20kHz, create the .txt file, copy/paste that data from the.txt file into the Excel file, and the information in the "Copy to .ady" column only transfers 10Hz - 10kHz. The "Freq" and "SPL" columns shows all of the data points from my .txt file. How would you change that to include all of the data in the "Copy to .ady" column?
I use Shift + End + cursor keys on the keyboard to select all the way to the end of the data from the selected cell.
Audyssey cannot apply any custom curve point outside 20-20,000Hz range no matter what data you will enter. But if you want to still export them that way, I guess you'll need to increase PPO from 24 to 48.
Just an idea. Create the PEQ in REW, import in Rephase, export impulse response of the filters back in REW, create division of the imported filter versus a flat impulse. This would get the FIR filters from the PEQ. Just tested and seems to be working very well. You can also further PEQ the result and apply another bank of filter correction in Rephase for even further refinment of the initial response. Do you see any issues with this approach?
It should work but with one inversion in REW, you already create the required PEQ settings as custom curve edit points for Audyssey. Besides in general leess is more in digital correction . Too much eq especially in high frequencies will cause boxy sound. Try the method in Audyssey for Dolby Atmos music video where there's less correction and you might prefer that one for movies as well.
@@ocaudiophile Thank you! I will. I learned so much from your videos. I looked at one of my first measurements after Audyssey automatic calibration and it's night and day versus what I got following your methods!
@@horatiud.5976 Good to hear that.
When playing sweep file from media player, the response curve capture by REW is 15 db lower than the response curve captured by playing sweep directly from REW. What should be done?
Turn off loudness in the receiver. The menu comes up only during Atmos signal playback so can be hard to find. If that doesn't help then your receiver is one of the few models which applies dialnorm setting to Atmos signals and you cannot do much about it.
Hello buddy again i have 2 questions why i cant measure the subs alone and i have to run 1 speaker with the sub rew dont let me to mesaure it what settings i have to do ?? And second question i have connect the pc with optical cable to receiver and i dont know if this is the reason that i cant measure 75 db it show me less 40 50 and the speakers are very high... What i have to check...???
Unfortunately PC sound cards (and WIndows) have a strict maximum of 7.1 channels. The only way to measure subs individually is manually switch them on/off during measurements.\
I have never tried optical out, it might have peculiarities and I doubt it can carry Aymos signal. WHy don't you try HDMI?
Awesome! Do you recommend investing $80 for calibrated UMIK-1 microphone for setup or ok to use the mic that comes with Audyssey (I just purchased Denon x4800h receiver that have Audyssey multiq 32x with mic)?
Congrats on your purchase, that receiver has the same processor inside as the top models and is made in Japan.
You can use the Audyssey mic that came with the receiver but make sure you use the calibration file with it while measuring speakers in REW. You can find the the link to the calibration file of these mics in this video:

Have gotten great results with the addition of the Target curves to each speaker. I had to lower the volume on the subs since I have a miniDSP 2x4 HD for my 4 subs all time aligned and EQed flat. Thank you for all the tutorials. Even if I don't resolve the crashes my home theater sounds fantastic!
The original ady file should be produced in your own app and for your own receiver or else the I'D numbers don't match and might be causing the crashes

Just deleted the MultEQ Editor after moving the curves. Re-install the app and add the Original and Default files with the same result (crash on Default).
I'll re-run Audyssey tomorrow and perhaps try to edit an existing 8-position curve.
@@CarlosGomez-THX_1138 No need to go for all 8 measurements, you can end in just 3 measurements.
@@ocaudiophile I made a mistake copying the excel column 1 cell 1 into Original.ady. The transfer was successful! I can now proceed with the rest of the goodness!
Hello OCA. After - Pinpointing crossover frequencies for each speaker... I get following error - Error: Speaker has no bass response according to your measurement file. Please check! - program execution has stopped! Please let me know what I might be doing wrong.
Check your original ady file for absurd trim adjustment settings for subwoofer unless you've open baffle speakers with limited bass response.
Is there a possibility with an existing measurement to activate the 2nd subwoofer channel in the .ady file?
There was but MultEQ editor app got an update recently and now can host 4 subs and subwoofer syntax changed a lot. Your best option is to ask it in this forum:

I have taken measurements at the three points, and am now ready to time align them.
At about 20:30, you mention a new REW feature called something like 'copy selections to other overlay graphs'. How are you getting that pop-up that contains that new feature?
Mouse right click on the bottom window
@@ocaudiophile I must not be on the same version of REW as you, since that command is not available when I right-click on that bottom window. I am on the released Mac version of REW, version 5.20.13.
I found that there is a newer version (5.20.14), early access build. I installed that one, and it has the command that you use in your video.
@@ronaldippolito6785 Google "REW early access version"
Hi, how to use these protocols and what will be the benefits. I couldn't understand the use and benefits and how to apply. I've gone through the document but couldn't understand the application.
Better try Audyssey ART video method, it has automation scripts which accelerates the manual processes
At the 23:30 point in your video, you are going to vector average front left three measurements. You also included the copy of the time-aligned measurements.
Why did you include the three original measurements, if you had the time -aligned version?
All 3 measurements were already time aligned with cross correlation. The 4th is a copy of the central measurement and a copy of of a time-aligned measurement is also time-aligned. The reason I added the central measurement twice to the average is to give it more weight in the average. The reason for evarging them is to find the true speaker response in a larger area.
This is all really great, but I am confused about a discrepancy between the Speaker Level settings at two points in your video. At 36:58 you show values for, say, the LCR at -1.0/+2.5/-1.0, but at 46:00, after explaining to take a note of the Speaker Level and distances settings before uploading the curve-edited .ady file, you enter values of -4.0/+0.5/-4.5 for the same three speakers. How/why do those values differ when they should have been the same as the noted values prior to uploading the curve-edited .ady file indicated at 36:58?
:) Your attention to detail is amazing and you're right but in the middle of the calibration during recording the video, I figured I forgot to take a note of the levels so I used levels from another measurement. Just ignore the differences and follow the method!
@@ocaudiophile Thanks for that info - good to know, and now my brain can rest easy :) I did have another question after giving this process some thought: If one doesn't like what Dynamic EQ does to the sound in one's system, does this method work without having that enabled? I find that DEQ really bloats the bass, and makes it sound too overbearing, so I personally turn it off.
@@discostu668 I never turned DEQ on myself for the exact same reasons but this method tames all its disadvantages at the usual volume level you listen to your system and makes use of its boosts at lower volume levels. If you still don't want to use DEQ or DV then you can do a manul calibration with Graphic Equalizer. You'll find two videos on that in my channel.
@@ocaudiophile That is also very good to know. Once I get around to the small re-arrangement of my HT system, I'm definitely going to try this method out. Thankfully, I'm only running a 3.1 system, so I won't have to go through so many measurements! I'm looking forward to seeing how this method changes the sound in my space. The thing that struck me the most was the method used to determine the speaker crossovers.
I have a question: which sounds do i need to play? Your wav files or the sounds from REW? And where is the advantage?
Use supplied mp4 files for all measurements
I have always had DEQ off as I find its boosts the atmos channels too much. Does this process work if DEQ is set to off?
It sure does and as long as you are ok with listening to your system at the level you measured, it will even sound better overall.
