I got a UMIK-1 mic for Christmas. I just finished watching parts 1 & 2 and am overwhelmed! I need a simpler video on how to use my mic and REW so I can create the files and use NEURON. For now, I will create a new ADY file using my Marantz SR8015 Audyssey mic. Its going to take a few more views of part 2 before I can figure out how to use REW and mu UMIK-1 to calibrate my system.

Unable to locate 'Transfer optimized calibration to receiver.bat' file on your Google Drive, where to locate this? pls advise

Please include support for Denon S760H and S770H models 7.1 Atmos

So what’s next OCA? We’ve gotten so used to regular releases, which was simply incredible over the Christmas period. My system sounds amazing! But I saw your comment about filters not working in 1.6. Is there a wishlist you’re working towards?

Hello, why am i getting the error SW2 is missing in configuration list? I added a 2nd sub onto 4800 and did directional measurements on the multeq app. my measurements are sw10 to 17 and sw20 to 27

Is thereva Wayne to convert oca to ady?

Programm ist für den laien gut, das wars dann leider auch 😊 etwas besser als mit der Audessey App! Holt euch nen Profi, der alles separat misst und ihr werdet tränen in den Augen haben 😊 wie gesagt, etwas besser als mit der app aber das wars dann auch 😊

Thanks for the input, but you can remove the subwoofer, not all of us have a sub and I have to generate it automatically or how can I make it not ask for a subwoofer or central speker. I have a 4.0 sistem

I ran the 1.6 script with "Remove Marantz Sound" and "Enable LFE + main" set to false. The script gets stuck on [INFORMATION] Analyzing alignment at 20 Hz...[0%]. Is this normal? For information, the script runs correctly with "Remove marantz Sound" and "Enable LFE = main" set to true.

Hey OCA, is it normal that i get '11:09:06 AM [IMPORTANT] SW1: 2.87m (9.42ft), polarity inverted? true' for my sub, but in the rew neuron results sw1filter impulse is the same as all other filters which have 'polarity inverted? false' ? Also the predicted and original sw1 response seems of the same direction...

Cross cor allign and Vector allign are all missing in the new versions. Where do i find them? How can i use them now? Nothing is documented on there webside

Many thanks for your knowledge, and the presetation of how to do it.😊

Hi, There seems to be an issue with the v1.6: Uncaught (in promise) TypeError: Cannot read properties of null (reading 'delayB') at alignImpulses (A1 Evo Neuron Preview 1.6.html:1163:27) at async alignSub (A1 Evo Neuron Preview 1.6.html:1429:50) at async main (A1 Evo Neuron Preview 1.6.html:430:36)

Oca why i cant load the file of neuron to multieq app?

Amazing tutorial! Thanks a lot for this!

Hi Serkan... Everything worked as a charm and a definte upgrade to the musicality of my HT, the Sub is tight and accurate and sounstage just perfect.. My learnings : 1) If you have the stock Audyssey Mic create the ADY file using Neuron and dont go the manual REW measurements somehow stock mic doesnt work well with REW 2) For me Harmon curve works the best... Thanks again all fearures of Neuron is working perfectly...

This may be a silly question but on the REW program i dont have an API tab, how do i gwt one?

Great work OCA! I am upgrading from A1 EVO to Neuron. I got my .avr file, did my .ady extraction, but I cannot locate any .mdat file that I need to load into REW to start optimization. Any suggestions welcome. Thanks!

Thanks for your great work!

I just ran my first A1 Evo Neuron calibration with the A1 Neuron curve, and wow, THANK YOU. There’s a number of settings on the main html calibration tool about boost min/max, lfe+main on/off, etc…. What should these settings be?

Hi, works great! Thank you very much for all the effort. Just one question: When I upload the original calibration .ady file with "upload calibration" and open the downloaded extracted measurements, there is a _micCal.txt file included in the .zip file. When I run the optimization and look at the response data of the generated master.ady file, I see the inverted _micCal SPL response instead of the flat "perfect speaker" response. Is this intended? Looks to me like a double mic correction since the response data in the .ady is after mic correction already. So should be flat. Another question: is there a way to add own PEQ filters for the various channels before generating the optimized .ady file in order to correct known speaker imperfection?

this seems like a great tool, but it just doesn't work for me, no matter how many different ways I try. The subs are always summed when using the mobile app, which is the only way to get the actual .ady file. So i get the message to measure them with "odd.wtf measure -b". When I do that it measures the speakers and then fails to retrieve the response when it gets to the SW1. Measurements position 1 failed! Message origin is 0 but only 1 is expected! !! Unrecoverable error. Must abort measurement. No measurement positions completed. Will not write anything to file. I have tried this no less than 10 times and come up with the same thing every time. I have rebooted the PC, the Marantz 7706 and swapped mics. I'm glad its working for others, I can see alot of work has gone into this. Keep up the good work. 👍

Wow it’s taken me about a month to get the script working for me but it was worth all the head scratching 😂thank you OCA you are a true gentleman 😃😃

I got everything dialed in pretty well except that my distances are off. I seem to remember you saying all updates need to up changed in the script but I don't really know how to do that. Are distances in that or should I just update them in the AVR after uploading the .oca file?

Which target curve is best for my room, receiver Denon x4800h, Dali oberon speakers and an atmos 5.1.4 system. My bass settings after rew measurement and sending to my avr is 5 to 8 db +, is this normal?

Do we think the manufacturers will ever block this mechanism via a firmware update? I’ve turned off auto updates just in case!!

Hi Mr Oca, first of all congratulations for your amazing work. I'm trying to use the new version 1.6 with identical xover and NotDrToole curve but the script stops at INFORMATION Analyzing alignment at 20hz... (0%). If I try without the identical xover it works fine. I'm using the latest REW. Hope you can help me out with this

Once the calibration file is sent to the AVR, can I use Audyssey MultEQ phone app to transfer the calibration file saved to Preset 1 in the receiver to my phone? If YES, Will it save to my phone as an ADY file?

V1.6 Am using TC evo Neuron increasing bass to 6dB and bass fill by 1dB. Denon x8500h is spot on using LFE + Main. Have 2 SVS PB1000 with slightly different distance of 2.5metres(ish). Even though polarity is known, Neuron inverts one with sw1@ 2.5m and sw2 @ 7.2m inverted. Weird but sounds amazing. Big appreciation to OCA and team. Had massive issues prior to 1.6 with dual subs so was using a splitter and one sub output. Was good but 1.6 was worth waiting for. Love I can use odd.wtf or mqx.

Error with latest version V1.6: Process starts, gets to the 'reverse the AVR 250Hz LPF' step, when REW makes about 100 copies of a measurement called "A times B", then fails with the error. 9:25:39 PM [ERROR!] An error occurred while processing measurements: Error: Network response was not OK! Using Beta 66 and Beta 67. Chrome and Firefox.

sorry if this is a stupid question, but I generate a .avr file for use, but there is never another mention of the file and how to optimize it.

Hi there, I am receiving this error: [WARNING!] Imported measurements in REW are missing data for each of the 2 subwoofers in your system! [WARNING!] Repeat measurement process with 'odd.wtf measure -b' 'directional bass' mode hack (will work with your reciever model). [ERROR!] A1 Evo Neuron cannot optimize your system without individual measurements for each subwoofer! It worked flawlessly with the A1 Evo! I have 2 subwoofers.

So after many days of calibrations im closing in on my final runs......one thing is that i cant choose LFE+MAIN before the script starts?I tried with ady file that had all speakers small w sub and also one with fronts as large before adding to REW for processing.....still cant change the slider????

OCA , one quick question . Is it better to measure the individual subs on the receiver with the respective output (AVR 2 sub out - 2 subs connected) , or just one sub connected and the other (s) daisy chain , connected in line ? Measurements made with REW and UMIK 1 ? The last Neuron (19.01.2025) really works better, i feel the bass now

Hi OCA, thank you for efforts! I appreaciate this a lot! I tried to start the (maestro) script and it says that it can not run because I have no subwoofer. Is there a possibility to use Audyssey One without a subwoofer?

Hi there! Using the 1.6 Neuron with AV10 and three (different) subs, sound is quite good. But when inspecting the .oca/json I am wondering why the filter settings are exactly the same for all three subs? I would expect individual filter settings as each sub has an individual output? Sub-distances seem to be reasonable. Neuron was feed with .ady measurement set to directional bass. Any ideas?

Quick question OCA: What type of measuring pattern do you recommend with the Audyssey app for neuron? Standard 8 point or is there something else i should do... for example like 101 or a pattern like secrets of audyssey recommends? Thank you in advance!

Thanks to the new information and updated version, I wanted to redo the calibration with the LPF + Main option for my home theater setup (Denon AVR-X4400H). I performed new microphone measurements using the new odd.wtf script to get measurements for SW1 and SW2 since my receiver natively does not support this feature. When I finished, everything worked great in Neuron, but I got error code 1: "loading final filters." while transfering settings to receiver. Then I redid the calibration using the old measurements I had, and this resulted in the following message in Neuron: 10:03:07 [WARNING!] Imported measurements in REW are missing data for each of the 2 subwoofers in your system! 10:03:07 [WARNING!] Repeat measurement process with 'odd.wtf measure -b' 'directional bass' mode hack (will work with your receiver model). 10:03:07 [ERROR!] A1 Evo Neuron cannot optimize your system without individual measurements for each subwoofer! I understand this message except for the "measure -b" part. Can you elaborate or explain this for me, please?

Thanks for your dedicated effort and support. A game changer.

You have commented out all-pass filters in version 1.6, why is that? Was there some kind of a problem with them? In my config, they helped to smooth out some dips around XO frequency.

Hi very much appreciated for the time that you put in to do this. Can I give a request?? To create a video from start to finish, including setting up the microphone (90 deg or horizontal, you have different videos stating different things), placement, measurement settings and step by step instructions without any explanation or jumping around to different areas. Just step by step the way you would do it without an audience. This way we can follow along step by step. The lengthy explanation )(though extremely beneficial for us to understand why you are doing what you are doing and what the results are) make it very difficult to replicate the steps on our side. Again, not to complain because you are giving invaluable information. anyway you can make a straight forward video, start to finish, step by step, would be incredible

Applied the Neuron script today with Denon AVR and 5.1.4. setup. Total gamechanger. It‘s actually shocking when I switch between speaker presets Audyssey app vs A1 Evo Neuron optimization: It’s such a noticable improvement! There are some surprises regarding crossovers, e.g Fronts are now set at 120hz crossover (despite two woofers each) while lesser equipped Surrounds are set at 40hz. And sub was boosted with +7,5 db which I had to reduce a bit. But what matters is the overall sound experience. And it’s just amazing! For 3D as well as 2ch stereo. Thank you Oca! Question: Do you have a Patreon site?

I tried this and removed the minidsp did sub 1 and 2 directly to the denon for measuring in REW manually, I assumed the best way is to unplug one sub at a time and run the "SWx" atmos sweep, name the file "SW1" and then plug in only the other one, replay the file and name it "SW2" was that the correct thing to do OCA? The final product seems to measure well after calibration upload

Not sure if this has been asked but will biamping front speakers cause any issues with neuron?

Great sounding acripts! Confrats! How can I introduce aditional filters considering I know how to use Rew? I have close measurements from the speakers with some issues to be be corrected at mid / hights. Will be very helpfull to be able to introduce them in addition to the low end that evo creates. Thank you in advance!

Quick question. Dual sub setup, both the same. Think I’ve got them in a good position after using REW. Does neuron do everything else - timing, phase etc?

How can I convert the oca output file back to ady so I can change them on the fly within the MultiEQ app?

Hi OCA. Everything is working with 1.6 and Evo Neuron curve. It sounds good as always but i was wondering about the trim levels in the final result and if it's considered safe and if there's a way to limit them because what i try with the sliders doesn't seem to work. I'm using an X3800 with an external 5 channel 200w @8 ohm (350w @ 4ohm) amp and 2 SVS subs that can do 350w. The C, SL and SR are efficient Klipsch floorstanders and center (both 8ohm 98db) and power hungry Elac fronts that are 6 ohm 86db. In Audyssey the fronts are about -1.5, the C is -7.5 and rears are -11 and -7. The subs are -5.5 and -5. After running 1.6 the trim levels are now 2:45:20 a.m. [IMPORTANT] Speaker FL: +5.0dB 2:45:21 a.m. [IMPORTANT] Speaker FR: +5.5dB 2:45:21 a.m. [IMPORTANT] Speaker RHL: +0.5dB 2:45:21 a.m. [IMPORTANT] Speaker RHR: +0.5dB 2:45:21 a.m. [IMPORTANT] Speaker SBL: +1.5dB 2:45:21 a.m. [IMPORTANT] Speaker SBR: +1.5dB 2:45:21 a.m. [IMPORTANT] Speaker SLA: -8.5dB 2:45:21 a.m. [IMPORTANT] Speaker SRA: -5.0dB 2:45:21 a.m. [IMPORTANT] Speaker C: -4.0dB 2:45:21 a.m. [IMPORTANT] Speaker FHL: +1.5dB 2:45:21 a.m. [IMPORTANT] Speaker FHR: +1.5dB 2:45:21 a.m. [INFORMATION] Final target level:: 73.69dB 2:45:21 a.m. [INFORMATION] Alignment accuracy: ±0.14dB 2:45:21 a.m. [INFORMATION] Calculating optimal subwoofer volume offset... 2:45:21 a.m. [INFORMATION] Available range: -11.5dB - +11.5dB 2:45:22 a.m. [IMPORTANT] Final subwoofer volume: 9dB. With the powerful amp is it a problem running the fronts at the +5 to +7 it often assigns, especially when the other speakers are so low in comparison when drawing current? Also the subs are generally assigned +9 to +12. I do have a dip on one sub but regardless the almost max level adjustment has me worried i will overload or clip the sub. I guess my question is although the settings seem high by conventional standards is your script doing magic behind the scenes to compensate for this using filters where it's 100% safe, or should i use caution?

hi and thank you so much for making my system come alive!!! Question....When prompted to change "isReversePolarity ticked (true)" in json editor........(as my sub is only capable of 120hz +-3db and A1 reported it as 250hz,ok Audyssey did) Where do i change it? Because there is so many channel numbers in the text, is it the first one thats in the beginning of the text file: (Highlighted with space and THIS???)
