Love it, love it, love it!!! Want to try ti right now but I'll wait for my new speakers since I'll have to redo everything when they arrive anyway. Amazing stuff man! Keep up the awesome work!!!
Seriously I celebrate everytime you push content wether written or in video. Big thanks OCA big fan of all the work you are doing. Very excited for part 2
Very excited about this! Very excited for part 2 tomorrow. I hope it comments on how to deal with numerous subs for receivers that don't have directional bass that would be amazing... But I'll wait for part 2 before asking specific questions. Thanks again for all the work you are doing for this community.
Thank you sooo much ! 😃 May I ask you to put me in the right direction? I have successfully done your standaard redo of the ady file, but I would really like to tweak the settings in the script, like freq range. I found the settings, but not hów to change them, or how to get the script to run
Open the script in a text editor, make the changes you want and then save (keep the extension .html during saving). Even Notepad will do but I suggest sublime text as it becomes a lot easier to read.
@@ocaudiophile I did not know I could download the whole page including script to my hard drive, make changes and it would still be functional. Got it now! Even though I set endfrequency to 20000 Hz, it still seems to limit corrections to 1000 Hz though... 😄
As many others have said , thank you sir for putting in the time and efforts that you do to make something as great as this and put it out there for anyone to use "especially the one like myself who dont come close to having the knowledge to optimize their systems the way your scripts do" and then go even further and spend more time and effort to make it possible for someone to be able to customize it to there liking if they wish. Thats basically the equivalent of a artist spends months on a sculpture and then giving it to someone along with the tools they would need to change it how they see fit. That says a lot about a person. I truly appreciate your hard work and willingness to spreed the love. With that said, i am having hitting a road block early in the process which is getting my multiEQ measurements sent to my computer in a format that i can drop it into REW. Every way I've tried to send it, it is saved in the wrong format. And thats if i even able to send it at all. Most efforts are roadblocked with some sort of error message or a incompatible message. Any help is obviously appreciated. Thanks.
Nexus is for measurements you do on your own in REW. If you want to use Audyssey's measurements in the MultEQ app, use A1 Evo Maestro: th-cam.com/video/lmZ5yV1-wMI/w-d-xo.html
Superb work! It is really insane what you were able to create! And don't apologize for the delay. You are doing this in your own time, and we get to enjoy your hard work. In my opinion, it's done when it's done. And if a release date gets pushed, it's with good reason. Better to get it right and fewer questions from people then to rush it and create too high work pressure for yourself. MJ was already great! Very curious how Nexus will sound. Since I have that stupid 40-60Hz bug (Thanks D&M for not taking it serious). Nexus is a superb way to work around that and finally get good and trustworthy room correction.
I managed to take measurements without the bug after many trials (80% of the time they are there in my setup), no clue what causes it to go away but they may disappear at times. So at least with Nexus we have a chance of catching the right time for measurements ;)
@@ocaudiophile Did you find any way that it was more consistent? or was it a lottery? I have not been able to get matching measurements anymore. Yeah cant wait for that! the UMIK1 i have will also be quite a bit better and its calibrated. So that will also make quite the difference.
I will try this today. Which house curve would you recommend for movie watching? My sub goes down to 19hz and I have 5.1 setup. I listen movies between -30 and -15 dB. Depends how late it is and who is watching it with me. Thank you.
Hey OCA, did you ever consider doing the same thing with Dirac? Maybe it is possible to transfer corrections to the AVR into the Dirac locations. Well, probably encrypted... ?
This looks great. Before starting to use it I have a question. My set up is a little different than standard. I’m using the Marantz AV8805A for both stereo music as well as 13 channel HT video. I am running an active crossover filter so my subwooofers are hooked up to this filter to deal with low bass. Upper bass is amplified by a SS amp and hooked up to the bass speakers in a tower speaker. The mid and high speakers in the tower are powered by a tube amp. So therefore my Marantz only has large main speakers and no woofers directly connected. That means your tool would not work for me. Correct? Can I manually add dummy woofers in the ADY file in order to make your tooling work? If so, what settings would you suggest?
Nice setup and you could in theory add a dummy sub measurement for the script to work but it wouldn't give you many useful results other than distances and levels without even the bass content going to speakers.
Does the Notebook/PC need some special requirements (e.g 5.1 soundcard?) to run REW and send each channel sweeps? I only have an 10 year old notebook, does support HDMI output, but theres no surround sound soundboard in it. I am exited to see part 2, maybe my question is getting answered. Many Thx for your incredible work!!!!
Where do you get this first calibration file from? Is it from MultEQ? From REW? Some parts of this video feel like they omit something important. EDIT: Nevermind! I never really noticed you can just share the MultEQ measurements like a file!
You can set Nexus distances, channel volumes and crossovers and use manual EQ on your Anthem by applying Nexus PEQ filters. There are some people who do that. I also have a script that decodes .arc3 files to REW I think linked in Audyssey ART video description.
@@ocaudiophile last question and i dont disturb u anymore haha, is it better if i do the sub alignment with something like MSO and minidsp and treated them as 1 in evo or is it not neccesary?
Nexus generates the same filters for every Audyssey version but lesser versions use lower resolution filters but I haven't heard any complaints so far.
No, the whole algo is based on the presence of a sub but you can load a dummy ady file with a sub and force LFE + Main. This will calibrate your front mains perfectly. Still you will have crossed over C, SL and SR with an non-existent sub!
@@hawki1980 open file with online json editor. Duplicate your front left of front right speaker then rename to subwoofer save it and run it with the script.
Very cool script!!! 😎😎😎 I would like if one doesn't have to 'upload calibration' every time. The calibration files don't change often but i would like to generate with different target curves....
Thanks. Will nexus allow us to get directional bass with mini-dsp on older receiver (Denon x4700)? If so then I will invest in minidsp and two more subs!
One thing I don't understand (sorry if it's a stupid question): to reset all setting I have to upload this ady file. But as far as I've seen there's no such thing as default ady included in the downloaded package. So how do I achieve this reset without this file? Just reset the AVR?
I'm very behind the lingo and curve in this community. I uploaded my most recent .ady file to Nexus, download the "Create REW... ... w/Dynamic EQ ON", sent it to my X1600, and my speaker levels are not all at zero nor are the distances at zero. Should I manually make them all zero before proceeding to part 2?
Yes you can manually set them but make sure the ady file has really been transferred to your receiver because it bypasses Audyssey filters which cannot be done manually.
@@ocaudiophile I believe/hope it has because it changed all my speakers to large, which I know were not large originally. Thank you for responding so quickly. I'm trying to not get overwhelmed with following your video (part 2), but there's so much background knowledge that your regular audience has (I assume) that it's difficult to stay motivated and finish this.
I ran REW internal sweeps for 5.1 and every time I optimize in the script, REW gets to a certain point and then I get an error message in REW called Java.lang.nullpointerexception. Any thoughts what might be causing this or how to fix it? This is on a MacBook if that makes a difference.
@@ocaudiophile That did the trick. I had one other question if you don’t mind. I had to run the sweeps at -20 on my receiver and dbfs at -12 to avoid high distortion notifications in my rear channels, when entering the volume setting into the script should I enter -20 or -32 to take into account I ran the sweeps 12 db lower?
Thank you very much for your work, Big Fan!!! datashet of my dali speakers says that the minimum crossover is 46 Hz and Nexus says to put them at 40 Hz my setup 7.2 Denon X3800H c: dali ikon vocal mk2---Nexus says 90Hz FR: dali mentor 1-----Nexus says 40Hz FL: dali mentor 1----Nexus says 40Hz SLA: small satellite-----Nexus says 200Hz SRA: small satellite-----Nexus says 200Hz SBL: small satellite-----Nexus says 200Hz SBR: small satellite------Nexus says 200Hz What do you think i should do ?
That's wall (boundary) gain and quite normal with the fronts. Satellites are a bit too high though, bass localization may start to become a problem. Are they really that small?
@@ocaudiophile okay thank you very much for the answer yes my satellite speakers are Bose FreeSpace 3 I can't get bigger speakers from my wife (:.. soon to use evo Neuron in REW with umik-1 which spl level should I use for my 2 subs when I get an error with too small a level for ground floor noise. have else set the spl level for all speakers to about 75
@@ocaudiophile Found it, used it. Didn't let me comment, though. Just wanted to thank you, again, for all the great work you're doing for the community. And now I've been able to find the post and edit it. Guess it just takes time, and patience in NOT one of my virtues. Michael

Can A1 Evo Nexus be made simpler? I have used A1 Evo and the effect is very good, making the sound very pleasant. However, the operation of A1 Evo Nexus is very complicated. From the video, it may be limited by the video clarity. Although I have used 4k, it is still difficult to understand the operation steps. Can you give me a simple process or tutorial so that I can use A1 Evo Nexus?
@@ocaudiophile It would be great if it could be as simple as the A1 Evo Maestro MJ. I hope the tutorial for the A1 Evo Nexus can clearly tell us what to do in the first step, what to do in the second step, and what to do in the end. Most people can succeed by following the video content and then enjoy the shock that the A1 Evo Nexus brings us.
It could be an Android bug requiring Google drive usage for ady file transfer. I don't have Android but there's a facebook group "Audyssey One" with lots of experts on these things.
It would be fanatastic if there is nexus for hifi users, not av users. Common pc-dac users want nexus too!!! 😢 is it impossible to get nexus pc only version??
Hello OCA, Evo Maestro working ok for me, but i want test this, lets say more detailed calibration. But after my measurements I find two problems. 1, Is possible to change VLC traks for some save range (Hz) for speakers? Mean, 20hz - 20Khz. My surrounds have really big distortion, and big movements when they are tested in low fq. Like 5-10 hz, which they can't play anyway. Im afraid if it is save for them. 2. Is in script or browser any debug console, where I can check what exactly that script doing and where waiting for REW? Because I'm not able to successfully finish Nexus calibration. Always is stopped somewhere during Hilbert transformations. Each time in same speaker and just stop. No errors, no warnings.. just don't do anything. Aplying filters and do that magic for first 5 measurements, but on that 6th. just stop and nothing. Tested the newest 1.5 script. But didn't helped.
v1.6 will fix it. You probably uploaded an equalizer to REW before the measurements which was the cause of most errors. You can save the complete log by mouse right click/save as at the end of the optimization.
@@ocaudiophile Tested 1.6, but same. Calibration stoped working, when try do hilbert transformation on SLA speaker.. where I have a huge distortion on low freq. I have on measurements for the SLA/SRA speakers in 20-30 Hz, 85 SPL distortion...., It is equal to signal level. And I'm not sure what can be the reason for that big distortion. Maybe wrongly configured sound card on old notebook? Clipping of the amp not, because I'm using external one, with some extra power... VLC also play it on 100% no distortion there. I will make some other tests via different sound card.
fixed issue by updates your script and using mp4 files, seems lossless atmos had a some issue, with distortion. Im not sure. But it was also updated in your files. About that stopped script, it was stupid fail, after reinstaling I forgot set measurements limit to 500, it always stoped on 30 :)
Make sure your AVR is on and connected to your network. Even then, some time you may need to run it multiple times until it catches up. If all else fails, try running the .exe from a command prompt.
I still dont get how the get the "ady" file? Yes if i had ANY ady file which matches my speaker setting i could "prepare" it with nexus....but i have no ady file and i dont get how to get this file? Receiver Backup doesnt contain this file MultiEQ App doesnt give me this file Rew doenst give me this file So i fail just at the start, anyone a hint for me?
@@ocaudiophile Thanks for the hint, now i have one, the original file created with multieq can be send to the avr, the one after nexus cant be send. It stops always at "data initializing" and after a while it says sending failed, restart the avr and try again. I have no problem with isReversePolarity I have a 5.1.2 setting and checked it in the receiver web menu twice, it matches In the ady file are all speakers present with the correct commandid Transfered the ady file with different methods to the phone (whatsapp, mail, file transfer/cifs), always the same Any idea on this? Edit: Thanks to avsforum, the solution is to change source to anything else than TV/audio
I do have a question about the network access.. I know this is not supposed to be covered here but my X4400H is not able to access with IP address. It keeps saying error 403 forbidden. However, the denon app has no problem
getting Selected file is either corrupt or not in correct format, using windows 11, one drive, then save to s24 samsung phone, import into audyssey, try to open the AVRecieverREWmode.ady file in multieq editor and it say corrupt. havnt had any such issues with previous builds
I think with some Android app versions (I don't have Android), you need to use Google drive for cloud transfers. FB group knows how to work around that.
@@ocaudiophile No luck, still corrupt. The ady file differs with the one from my Denoen AVR because yours has line feeder and the original one from Audyssey not.
Hi, I'm unable to send the .Ady file to my Denon AVR -3600.. keeps showing an error, transfer failed. I've tried everything and the outcome is the same.
For those that is experienced similar issue as mine with my Denon 3600H. I manage to "solve" the issue. 3600 has a bug apparently, my initial measurement was using 4 position. Solution is to use 3 positions and I was able to then transfer the Ady file to my AVR.

@@ocaudiophile thanks for the reply! Seems like I cannot change it as the MacBook doesn’t recognize the input at all. Might have to buy an adapter to have TRRS that the MacBook will recognize as a mic. That or I can buy a dedicated external microphone for better measurements. I’ll enjoy the A1 Evo Maestro as of now 😊
By the way usually when using branded/trademarked things (Audyssey in this case) you definitely should add some disclaimer that says that the script is in no way associated with Audyssey labs. I could see them make a complaint because you're associating Nexus with it. Something along the lines of: “Audyssey is a registered trademark of Audyssey Labs, Inc. and is not affiliated with A1 Evo.”
Has anyone compared this with Dirac auto-calibration results? I am really hesitant if I should get a new AVC-X6800H ($$$) or a 2nd hand SR7015 ($). If A1 Evo Nexus result is already comparable or better than Dirac, I'll just save up and get the SR7015. Any experience sharing is appreciated!
I have a 3080 running 5.2.4 and have both dirac and a1 evo. I think evo gives me better overall sound. I thought Dirac sounded great when I ran it, but its just not that close to a1 evo.
I wish you had a better mic setup. It’s ironic that I have a hard time understanding you with the combination of your accent and room echo coming through your mic.
We are unworthy of your generosity. Once again, OCA surprises us with an early Christmas present. Where on earth do you find the time to implement all this? Do you have a suggestion for all those who do not have a separate mic input, e.g. on their laptop? The Audessey measuring microphone has a TS 3.5 mm (mono) jack and is therefore not recognised by the internal sound card. At least this is the case with my laptop.
@@ocaudiophile Checked privacy settings, troubleshooting performed, the Audessey microphone is not recognised. At least on my laptop (HP) which has a single input (for headset). I guess I need a TS to TRS adapter, otherwise I'll have to solder something together
Thank you for the effort and thoughtfulness in putting this script together. However, It looks like people are still going to have to use a generic target curve with the new script. From personal experience having used many generic target curves in MultEQ-X, generic target curves never worked for me in my room. generic target curves are only guesses and the majority of the time they don't work. I always felt that something was missing using generic target curves. Your speakers will always sound anemic and you will never achieve the wide dynamic range that your speakers are capable of when using generic target curves. To get the best sound, wider dynamic range, cohesion out of your speakers you need a speaker frequency response correction software that can calculate a target curve for each of your speakers based on your room acoustic characteristics, speaker/boundary interactions, and speaker distance in relation to the MLP. You need speaker correction software that will derive a true target for your unique room and speakers.

To see your receiver under media devices on your pc, did you already have your receiver connected to your pc via Bluetooth or hdmi?
hdmi but it's in the wifi network
Thanks. Will nexus allow us to get directional bass with mini-dsp on older receiver (Denon x4700)? If so then I will invest in minidsp and two more subs!
One thing I don't understand (sorry if it's a stupid question): to reset all setting I have to upload this ady file. But as far as I've seen there's no such thing as default ady included in the downloaded package. So how do I achieve this reset without this file? Just reset the AVR?
Upload any Audyssey calibration you have and click "Generate REW measurement mode" file.
Will Maestro be the last build that utilizes measurements made through the Multi-EQ app?
There will be an update to Maestro soon with minor improvements derived from Nexus.
I'm very behind the lingo and curve in this community. I uploaded my most recent .ady file to Nexus, download the "Create REW... ... w/Dynamic EQ ON", sent it to my X1600, and my speaker levels are not all at zero nor are the distances at zero. Should I manually make them all zero before proceeding to part 2?
Yes you can manually set them but make sure the ady file has really been transferred to your receiver because it bypasses Audyssey filters which cannot be done manually.
@@ocaudiophile I believe/hope it has because it changed all my speakers to large, which I know were not large originally. Thank you for responding so quickly. I'm trying to not get overwhelmed with following your video (part 2), but there's so much background knowledge that your regular audience has (I assume) that it's difficult to stay motivated and finish this.
It's easier than you think.
Can not seem to find what soundmode should i set my x2800h to when going to calibrate? ( movie multi channel stereo? dolby surround?)
Just Movie/Stereo and it should auto switch to Atmos. If you are using REW sweeps and only have floor channels then Multi-ch in mode.
I ran REW internal sweeps for 5.1 and every time I optimize in the script, REW gets to a certain point and then I get an error message in REW called Java.lang.nullpointerexception. Any thoughts what might be causing this or how to fix it? This is on a MacBook if that makes a difference.
Sounds like a memory problem. Did you select 3GB while installing REW?
@ I did not, it selected 1 gen by default and I left it there. Just reinstalled at 3 GN and Re-running. Will see what happens.
@@ocaudiophile That did the trick. I had one other question if you don’t mind. I had to run the sweeps at -20 on my receiver and dbfs at -12 to avoid high distortion notifications in my rear channels, when entering the volume setting into the script should I enter -20 or -32 to take into account I ran the sweeps 12 db lower?

Thank you very much for your work, Big Fan!!!
datashet of my dali speakers says
that the minimum crossover is 46 Hz
and Nexus says to put them at 40 Hz
my setup 7.2
Denon X3800H
c: dali ikon vocal mk2---Nexus says 90Hz
FR: dali mentor 1-----Nexus says 40Hz
FL: dali mentor 1----Nexus says 40Hz
SLA: small satellite-----Nexus says 200Hz
SRA: small satellite-----Nexus says 200Hz
SBL: small satellite-----Nexus says 200Hz
SBR: small satellite------Nexus says 200Hz
What do you think i should do ?
That's wall (boundary) gain and quite normal with the fronts. Satellites are a bit too high though, bass localization may start to become a problem. Are they really that small?
@@ocaudiophile okay thank you very much for the answer yes my satellite speakers are Bose FreeSpace 3 I can't get bigger speakers from my wife (:.. soon to use evo Neuron in REW with umik-1
which spl level should I use for my 2 subs when I get an error with too small a level for ground floor noise. have else set the spl level for all speakers to about 75
The file created to reset measurements won't work in MultiEQ: "the selected file is corrupted or in an incorrect format"
There was a typo in the code and is now fixed with v1.1 in the download folder.
@@ocaudiophile Thank you
Where's the "Thanks!" button????
No idea
@@ocaudiophile Found it, used it. Didn't let me comment, though. Just wanted to thank you, again, for all the great work you're doing for the community.
And now I've been able to find the post and edit it. Guess it just takes time, and patience in NOT one of my virtues.

I can not get to the denon web control on my avr-x2800h, seems to just come up with a black screen with no menu when I go past the trusted site security
Check here if your AVR supports it:

Hello - I uploaded corrected ady file using the create rew measurement...w/o dyn eq but the file fails to open (File Corrupted) in the Multi-x app
It will not work on MultEQ-X!
@@ocaudiophile My bad i meant the audyssey Multeq editor
Can A1 Evo Nexus be made simpler? I have used A1 Evo and the effect is very good, making the sound very pleasant. However, the operation of A1 Evo Nexus is very complicated. From the video, it may be limited by the video clarity. Although I have used 4k, it is still difficult to understand the operation steps. Can you give me a simple process or tutorial so that I can use A1 Evo Nexus?
You are right that I should do a REW video soon. Maybe try Neuron in the mean time with your Audyssey measurements.
@@ocaudiophile It would be great if it could be as simple as the A1 Evo Maestro MJ. I hope the tutorial for the A1 Evo Nexus can clearly tell us what to do in the first step, what to do in the second step, and what to do in the end. Most people can succeed by following the video content and then enjoy the shock that the A1 Evo Nexus brings us.
What volume would I calibrate at if I usually listen to atmos at -12dB, but listen to stereo at -20dB?
I'd go for stereo level as surround sound is more forgiving.
How do you import the ady file to MULTIEQ editor app? when i press plus and import and then choose the addy file it says its not a curve file.
It could be an Android bug requiring Google drive usage for ady file transfer. I don't have Android but there's a facebook group "Audyssey One" with lots of experts on these things.
It would be fanatastic if there is nexus for hifi users, not av users. Common pc-dac users want nexus too!!! 😢 is it impossible to get nexus pc only version??
Hello OCA, Evo Maestro working ok for me, but i want test this, lets say more detailed calibration. But after my measurements I find two problems.
1, Is possible to change VLC traks for some save range (Hz) for speakers? Mean, 20hz - 20Khz. My surrounds have really big distortion, and big movements when they are tested in low fq. Like 5-10 hz, which they can't play anyway. Im afraid if it is save for them.
2. Is in script or browser any debug console, where I can check what exactly that script doing and where waiting for REW? Because I'm not able to successfully finish Nexus calibration. Always is stopped somewhere during Hilbert transformations. Each time in same speaker and just stop. No errors, no warnings.. just don't do anything. Aplying filters and do that magic for first 5 measurements, but on that 6th. just stop and nothing.
Tested the newest 1.5 script. But didn't helped.
v1.6 will fix it. You probably uploaded an equalizer to REW before the measurements which was the cause of most errors. You can save the complete log by mouse right click/save as at the end of the optimization.
@@ocaudiophile Tested 1.6, but same. Calibration stoped working, when try do hilbert transformation on SLA speaker.. where I have a huge distortion on low freq.
I have on measurements for the SLA/SRA speakers in 20-30 Hz, 85 SPL distortion...., It is equal to signal level.
And I'm not sure what can be the reason for that big distortion. Maybe wrongly configured sound card on old notebook? Clipping of the amp not, because I'm using external one, with some extra power... VLC also play it on 100% no distortion there.
I will make some other tests via different sound card.
fixed issue by updates your script and using mp4 files, seems lossless atmos had a some issue, with distortion. Im not sure. But it was also updated in your files.
About that stopped script, it was stupid fail, after reinstaling I forgot set measurements limit to 500, it always stoped on 30 :)
Hi Oca
Trying to open dyeq fix on windows but it keeps crashing.
Any idea what I am doing wrong
Make sure your AVR is on and connected to your network. Even then, some time you may need to run it multiple times until it catches up. If all else fails, try running the .exe from a command prompt.
Thank you that worked.
I still dont get how the get the "ady" file? Yes if i had ANY ady file which matches my speaker setting i could "prepare" it with nexus....but i have no ady file and i dont get how to get this file?
Receiver Backup doesnt contain this file
MultiEQ App doesnt give me this file
Rew doenst give me this file
So i fail just at the start, anyone a hint for me?
MultEQ app gives you this file after you run a Audyssey measurement by it.
@@ocaudiophile Thanks for the hint, now i have one, the original file created with multieq can be send to the avr, the one after nexus cant be send. It stops always at "data initializing" and after a while it says sending failed, restart the avr and try again.
I have no problem with isReversePolarity
I have a 5.1.2 setting and checked it in the receiver web menu twice, it matches
In the ady file are all speakers present with the correct commandid
Transfered the ady file with different methods to the phone (whatsapp, mail, file transfer/cifs), always the same
Any idea on this?
Edit:
Thanks to avsforum, the solution is to change source to anything else than TV/audio
I do have a question about the network access.. I know this is not supposed to be covered here but my X4400H is not able to access with IP address. It keeps saying error 403 forbidden. However, the denon app has no problem
It could be your browser security settings but I have heard some models that really don't have it.
@@ocaudiophile I see, no problems, thanks for the hard works
getting Selected file is either corrupt or not in correct format, using windows 11, one drive, then save to s24 samsung phone, import into audyssey, try to open the AVRecieverREWmode.ady file in multieq editor and it say corrupt. havnt had any such issues with previous builds
I think with some Android app versions (I don't have Android), you need to use Google drive for cloud transfers. FB group knows how to work around that.
@@ocaudiophile same thing, still corrupted...
@@ocaudiophile No luck, still corrupt. The ady file differs with the one from my Denoen AVR because yours has line feeder and the original one from Audyssey not.
@jojolino2 Hmmm. Can you share the original ady you're uploading? Google drive links are allowed in these comments.
@@ocaudiophilehave you checked the Nexus thread at AVS forum, someone spotted a small bug that might be the cause of this. Some brackets missing []
Hi, I'm unable to send the .Ady file to my Denon AVR -3600.. keeps showing an error, transfer failed. I've tried everything and the outcome is the same.
Can you send your original ady file without problems?
@@ocaudiophile sorry, to rephrase, even my original ady file cannot be transferred to the AVR. Wondering if anyone knows the issue
@@vick No clue but I am sure they have a solution for it in the Audyssey One facebook group.
For those that is experienced similar issue as mine with my Denon 3600H. I manage to "solve" the issue. 3600 has a bug apparently, my initial measurement was using 4 position. Solution is to use 3 positions and I was able to then transfer the Ady file to my AVR.

I connected my Audessey mic into my Macbook but doesn't show up as an input mic. Is anyone else having this issue?
MAcs have a setting to switch the same input between mic and phones. I remember to have mentioned that in the video
@@ocaudiophile thanks for the reply! Seems like I cannot change it as the MacBook doesn’t recognize the input at all. Might have to buy an adapter to have TRRS that the MacBook will recognize as a mic. That or I can buy a dedicated external microphone for better measurements. I’ll enjoy the A1 Evo Maestro as of now 😊
By the way usually when using branded/trademarked things (Audyssey in this case) you definitely should add some disclaimer that says that the script is in no way associated with Audyssey labs. I could see them make a complaint because you're associating Nexus with it. Something along the lines of:
“Audyssey is a registered trademark of Audyssey Labs, Inc. and is not affiliated with A1 Evo.”
It's there is it not?
@@ocaudiophile I'm an idiot, my screen was so big that I didn't see the note at the bottom. Don't mind me.
Has anyone compared this with Dirac auto-calibration results? I am really hesitant if I should get a new AVC-X6800H ($$$) or a 2nd hand SR7015 ($). If A1 Evo Nexus result is already comparable or better than Dirac, I'll just save up and get the SR7015. Any experience sharing is appreciated!
I have a 3080 running 5.2.4 and have both dirac and a1 evo. I think evo gives me better overall sound. I thought Dirac sounded great when I ran it, but its just not that close to a1 evo.
@@tedrobinson9034 Thank you for sharing!
9:00 anyone else feel that thump from the background sound picked up by his mic?! 😂
OCA what was that?! 😅a neighbour closing their door or something?
Could be me beating the keyboard :)
its ez to hear, you havent seen livingwithscottandkat... i bet they listen to all movies, in more like 90db hahaha
I wish you had a better mic setup. It’s ironic that I have a hard time understanding you with the combination of your accent and room echo coming through your mic.
You are right about both actually but the channel doesn't even justify the price of a good mic with what it earns at the moment :)
Slow down and pause as you talk. You sound like you are reading fast.
We are unworthy of your generosity. Once again, OCA surprises us with an early Christmas present. Where on earth do you find the time to implement all this?
Do you have a suggestion for all those who do not have a separate mic input, e.g. on their laptop?
The Audessey measuring microphone has a TS 3.5 mm (mono) jack and is therefore not recognised by the internal sound card. At least this is the case with my laptop.
@@anstra7028 external USB soundcard my friend :) I think a cheap one will work fine
@anstra7028 Shouldn't make a difference if the male jack is mono or stereo. Did you check if mic access is allowed in Windows privacy settings?
@@ocaudiophile Will check later and give you feedback. I've read others had similar problems, not in this use case but others
@@ocaudiophile Checked privacy settings, troubleshooting performed, the Audessey microphone is not recognised. At least on my laptop (HP) which has a single input (for headset). I guess I need a TS to TRS adapter, otherwise I'll have to solder something together
Thank you for the effort and thoughtfulness in putting this script together. However, It looks like people are still going to have to use a generic target curve with the new script. From personal experience having used many generic target curves in MultEQ-X, generic target curves never worked for me in my room. generic target curves are only guesses and the majority of the time they don't work. I always felt that something was missing using generic target curves. Your speakers will always sound anemic and you will never achieve the wide dynamic range that your speakers are capable of when using generic target curves. To get the best sound, wider dynamic range, cohesion out of your speakers you need a speaker frequency response correction software that can calculate a target curve for each of your speakers based on your room acoustic characteristics, speaker/boundary interactions, and speaker distance in relation to the MLP. You need speaker correction software that will derive a true target for your unique room and speakers.
Nice try!
Thanks!
