[@Pennywise782]

Thx for your work! Neuron is leveling my subs way too high. +12 and +11. I have Monolith 15 and I had to switch back the levels at least -8db. Otherwise while watching Top Gun2 the Subs are ripping my house apart. Was never so high. I used an Umik 1 and made the sweeps by manual.

[@Pennywise782]

And there is another bug in the script which causes a freeze. When I use custom speaker setting and disable the amps for front and center, because I use only preamp section, then the script freezes. I am using an Denon 8500 ha.

[@Majchel]

Hello OCA, one thing is unclear to me. I test LFE+MAIN on/off but always get a message: 17:14:20 [IMPORTANT] Optimized 'LPF for LFE' frequency for bass management: 250Hz And its strange because my mains can play lower than 35hz. After I upload my config to AVR, subb out is still only LFE. Should I manually set subb out to LFE+MAIN on freq. 250hz? Or when I upload the config, all will be set automatically. Because also my mains are crossed on 120hz, and all others on 60hz .. :) Maybe a quick summary at the end of the script will help also to others understand what should be done manually and what should not. Thanks.

Great work! I am beyond grateful for this script, it raises my nerdy enjoyment of movies quite a lot. I have the itch to watch so many just to hear more. I'm so giddy having access to allpass filters! Since Neuron 1.1, my center has cleared up remarkably. Another good side effect is that I can raise the volume in a large range and it never sounds uncomfortable, just more dynamic and realistic. Since 1.4, the spatial accuracy is much improved, something I've never experienced that strong before. The automatic inversion does this apparently. The system plays well with my 3 subs EQd with a miniDSP.

Thank you for your effort. You have drastically improved my movie experience and sound is at least half of movie experience. I need to play with house curves a little bit more and maybe repeat measurements with rew and more points. I am getting low crossover (60 hz) or high crossover (150hz) for mains, depending on house curve. Low means dip higher than 60hz, higher means localisation of bass. A1 Nexus crossed over my floor standers at 90hz and it seemed great mix with sub. However it still sound much better than Nexus. Also sub extends lower and at higher volume at low end 19-25 hz compared to Nexus. Thank you.

Finally - since A1 I struggled with Evo. Didn't have enough time for using my UMIK-1 with Nexus. Tried Neuron - amazing. Still puts +8db on my sub but it actually sounds incredible.

[@Hyacin75]

Wow!!! Several times over, wow! Wow 1 of course is the amazing new work, thank you so much. Wow 2 is the "ditch that mini" advice you gave regarding a MiniDSP below! Is that universally true? I think my X6700H can only EQ the subs as a single entity, so surely MSO on a MiniDSP would do a better job smoothing out their unique, individual responses? If so, in what order does one do the calibrations? I've been thinking recently of the idea of running A1, blanking out the sub curves, then running MSO? Rather than stacking filters? What would you say is best? Is "ditch the mini" universal advice?

[@ocaudiophile]

With an 6700 and more than 2 subs you need the MiniDSP otherwise not so much. Neuron can do everything MiniDSP can including individual filters to each sub, delays, trim and allpass filters.

Amazing results vs. classic Ady files. Audyssey with AVR, which includes a mic, can't compare with this script. I measured manually, via the UMIC-1 mic, day and night. Guys, when you invest more than 1-2K in the home theater, invest a little more for UMIC, donate OCA and REW creators, and move your theater experience on another level. Hope for the future updates, where we can manually set our crossovers, or little more adjustments from our side :)

@@NicholasRobertson-g6c, you need to measure manually via REW. I'm using the original sweeps from OCA. There is no other way; Denon does not have the correct measurements. After that you just run script, with measurements in REW.. script will make a *.oca file, which you can transfer to AVR.

Finally got around to doing this. Version 1.5 worked well with my Marantz Cinema 50. Significant improvement in my room versus Nexus. And that’s saying a lot because my room is really small (12ft X 7ft) with 6 foot ceilings 😅. Bass is much tighter now and everything is crystal clear. This Gik bass traps and acoustic panels are paying off! The only weird thing is it set both L and R crossover to 120. Works for me, but wondering why? Center channel is at 60 and it’s the same exact speaker as the L and R (Dali Opticon on-wall). Also it set both subs to +11, which was weird. They are both small Rel TZeros, but not sure why it set them so high. Both subs have the volume set to 75% to begin with. On an unrelated note, why are allpass filters suddenly possible where they were not possible before with Nexus? Why is Audissey calibration not taking advantage of them?

[@ocaudiophile]

Thank you very much, that's extremely generous and you didn't have to :) Crossover algo selects the frequency that will sound best at the MLP based on the response effected from wall gains and reflections. My identical Focal Domes get 80, 90 and 120 at 3 different locations. Nothing to be worried about it unless it picks something too high which might cause bass to be localized at the sub. Neuron sets the initial sub volume quite generously but uses filters to trim the peaks down. The overall level is always on the target. That's also harmless and provides less dips below target. Unless you get a "volume had to be capped" warning, nothing to worry about with that either. Neuron doesn't use Audyssey to talk to the AVR and unfortunately phase filtering is just another one of the many things they have left on the table.

[@Wordsalad69420]

@ But how is the magic happening? Neuron is somehow tapping directly into the DAC chip to make use of allpass filters? If you have link on the subject, I’d love to learn more about it. I’m a software engineer.

[@ocaudiophile]

@@Wordsalad69420 FIR filters used by the receiver are in fact impulse responses with phase content but Audyssey was sending just the frequency response content of that and in the past all we could do was to manipulate the frequency response shape of these filters with custom target curves as we were bound by the Editor app and Audyssey to send in the filters. This has changed now and we are no longer using the app. Instead using our own program now to communicate with the receiver and sending filters as they should be.

[@Wordsalad69420]

Thanks for posting this major update! I had one issue where my center channel crossover was set to 200hz. I looked at the log file and I didnt see anything stand out for this. Is it ok to just change it back to 80hz like it was with Nexxus?

[@ocaudiophile]

Firstly thank you for your generous donation. You didn't have to. Did you check the scores of C with other frequencies? Is 80Hz high but simply 200Hz is higher? If algo picks 200Hz, it will have a better frequency response at 200Hz xo compared to 80Hz but bass localization could be a problem especially with C speaker. Manually changing will not work, filter will not match the response. This custom version will set your Center speaker to 80Hz (despite what it may say in the log): drive.google.com/file/d/1lwISMER-EMgPmYV9RNwKRWNcRILBeJvE/view?usp=sharing

I want to be honest, even though you made it easy by transferring the calibration using the .bat files directly to the receiver. I personally preferred the old method of A1 Evo, using the .ady file in conjunction with the Audyssey App. Would it be possible to create an HTML for us, where we can simply get an .ady file back?

LFE + Main is automated with Neuron as all other settings but seems to be not working with certain models. Do you have a new model? .oca will be transferred to whichever preset your AVR is in at that moment so if you put in preset 2 before transfer, it will go to preset 2.

Hello together on the last day of 2024. Its so great what you have done here! THX for such a great work! Here is my feedback to the finally working version 1.4 on my denon receiver: My 2 Subwoofers working as one, now. Did the oca-File delete the directed setting? Bevore Neuron the setting was directet to Left and right speakers to avoid possible overturn or beeing to slow in stress mode like electronic music. I understand to less about the difference of neuron or this frequeny filters - if its better like this,now. The There is also no distance-mesurement (or calculation) for my second subwoofer. To go further, the bass is a bit to low or less "punchy" as with audyssey. But not everywhere. In some music-tracks or at Dolby Atmos is quite fine...but at XBox-Gaming (Star Wars - Jedi Survivor) it feels like "without the force". Maybe in 2025 it will be possible to increase the Bass (specially that "kickin") a bit? Next thing is, that i get a Message from my Receiver while looking in Manual settings: It told me that some of the Distances have no possible (or correct) values. I hope this will not have any bad effect. One strange thing is, that some Music-tracks and dolby atmos demos lead to pain in my ears. This wasn´t before and i had this problem a few years ago with wrong set speakers...and booming. But maybe this can be fixed with a bit finetuning in the manual setting of my receiver. Overall and in direct comparsion to audyssy (and ignored that audyssey overboosted all Surround- and Back-Speakers by allmost 10dB) Neuron sounds more "old school" or less digital...almost a bit more dully. But realy just a little little bit. Finally on big question remains: If i just boost the Bass-dB manually in my receiver, what will happen? Will it destroy the calculation of neuron and effekt other frequencies (to boost or lower them) or is it easy to use? Thx and a happy new year

[@BuffSquadBigBenni]

Do not check the distances in the AVR, or it will detect that distances are out of limits (due to the script bypassing the limitations) and adjust them accordingly. It is okay to check it on the web interface though. Just an observation.

[@carstenc3582]

Thanks for new version of your work! I am happy to work with it but I have to admit that I am quite sad that the secret class makes it much harder so interact with it. In my room I also want to able to change different things like start and endfrequency for example because the bass felt (up to 40 Hz in my configuration) not necessarily needs a cut by the script while the response profits of a higher end frequency of 300, sometimes 350 at max due to my bad room acoustics. Somehow I understand the obsfuction but the clear view up to v1.6 on what happens was something I admired and in my opinion was something great about your work.

[@ocaudiophile]

I’m sorry if the changes have made customization more challenging-that was never my intention. Unfortunately, due to instances of commercial misuse, I had to implement at least partial protection for my algorithms. On a different note, there’s no real need to EQ beyond the room transition frequency-224 Hz is already too high for that. While higher end frequencies may produce nicer-looking graphs, they won’t actually sound better. One of the three modes in Neuron 2.0 should deliver the best sound in any system. Plus, you now have the flexibility to fine-tune problem speakers by adjusting their distance from walls or using port plugs, guided by the detailed XO tables for further optimization.

[@carstenc3582]

@@ocaudiophile Okay, got it and I am on your side. It is really not okay if someone uses these tools for commerical use without agreement. We will live with that :) So, I still have the same issue that most of the time some speakers out of the 11 present speakers are not eq'ed the way I would expect. FL and FR for example are getting sometimes good filters that will lead to a good response and sometimes absolutely nothing is done by the script. Same for center speaker while others get quite complex filter with a good "looking" frequency response. In 1.6 I experimented with the timeout of the script but never had a real clue what the problem is. I have uploaded the avr, ady (I tried automated measurements for the sake of curiosity but the problem is also existent in my manual measurements) and the final filter calculation. If you find the time, perhaps you can have look into it (FL, FR, C) are the most significant while SRA is good example on what I expect what the filter should look like. To adress this issue I experimented with max boost 12 but it is the same problem when using 6 most of the time. It is also independant of the target curve but different calculations and adjustment lead to different speakers which filter does not really look as intended. Best regards and REALLY thanks for this great tool. drive.google.com/drive/folders/1KVjegE9AZ3KweRb-_GjUdtL1x7v3kujj

[@ocaudiophile]

I know what you are talking about. I believe this is a problem with REW auto EQ API...It randomly behaves differently to manual auto EQ and I couldn't yet convince John of the existence of the problem ;) In 2.0, I wrote a specific fetch function solely for "match target" api which waits full 5 seconds to complete auto eq process (hence the slowed progress at the end of the optimization) but it can still leave residuals sometimes although much better than in the case of 1.6. I am sure it will be totally fixed soon. Protip: The problem disappears when boost is 0dB!

[@ocaudiophile]

I checked your files, you have a small set of speakers I guess and 150Hz seems to be a good common XO for them. I don't see any reason it shouldn't sound good. Also EQ filters seemed quite nicely working. I uploaded a fixed script a few moments ago, older one was not going for "identical xo" mode as default although option buttons showed like it was. So maybe you didn't use that one. All I can say for your system is it will improve a bit if you can move SLA/SRA a bit further away from the walls (or port plug them).

[@carstenc3582]

@@ocaudiophile Thanks for looking into it! FL, FR are floorstand speakers and the center is a nuVero 70 - last time I run the script it was 40 Hz overall^^ the ceiling speakers are much smaller than the floor level speakers of course. This may be a thing - because one XO for different heights I would understand because typically the ceiling speakers are much smaller and may negatively impact the overall XO when only one valuie is used (this is the reason I have overwritten the array with my own crossovers in 1.6). When using different XOs, the script for examples currently gives me customXOs of FL+FR 40 Hz, C 90Hz. SBL+SBR 60Hz, SLA+SRA 80Hz, RHL+RHR 120Hz, FHL+FHR 150Hz. I really do not know how one single XO might fit these ;)

This may be dumb question but does this mean I can use my UMIK and take all the measurements from within REW and not via my Marantz at all?

[@carstenc3582]

That is correct.

[@MrBurny0608]

First of all thank you very much for your hard work. I had great results with the previous versions of A1 Evo. I also tried Neuron with the same .ady file I used before, but ran into some issues this time. I have pretty good towers for FR and FL but for some reason, Neuron sets a frequency crossover to 200Hz for them. It also said that the required subwoofer volume offset level exceeds hardware limits by 59.0dB and is being capped at -12dB. So no surprise that there is basically no bass when transferring the results to the AVR. I'm wondering why thats happening since the measurements were working just fine for the previous versions of A1 Evo. What do I need to change? Thanks for any help in advance

[@ocaudiophile]

Use "odd measure", don't use app measuremts. You are probably using a buggy Android app which is known to generate such absurd sub levels

[@MrBurny0608]

That was the solution. Thank you so much. Thats another huge step you‘ve accomplished. Sound is phenomenal.

[@SeanGreensmith-i3p]

I’m not going to look at the crossovers or anything once I’ve rerun Neuron. Since the genius work done is algorithm based, there are way too many variables at play to start tinkering with something just because it feels counter intuitive. Trust the process and your ears. Thanks again to OCA! Happy holidays!

[@ocaudiophile]

That's the right approach. Go back to the board only if you don't like what you hear (tip: it's not gonna happen!)

[@SeanGreensmith-i3p]

Agreed. It’s still telling me 4 speakers are out of phase though. They’re definitely not as I’ve double checked the cables. Is this deliberate or a bug?

[@ocaudiophile]

@@SeanGreensmith-i3p Polarity checking algo is very advanced but it's impossible to reach 100% accuracy there. It can misjudge especially with dolby enabled (place on top of speakers) speakers and center speaker due to their locations. Good thing is if the algo sees it inverted, it might really benefit sonically from inversion (unless it's a front main speaker). But if you are worried, you can swap speaker cables from the rear of the receiver and compare until I add something to avoid inversion if user confirms speaker is correctly connected in the script.

[@chandan6119]

All my fronts are set at 250hz and it sounds really bad. I think the script is very aggressive. Also it says my side surrounds and one tops as not in phase. With the same curve nexus sounds perfect. Waiting for the updates. Thank you

[@Jonesy1993]

Amazing, can’t wait to try it out. As i understood it you can take all your measurements and neuron will do the cross correlation and vector average with the mlp on top. All we need now is for rew to allow multi measurement from file and label the measurement in the order they are in the playlist.

[@ocaudiophile]

Yes all you have to do is measure your speakers with REW starting from MLP and name them correctly. The rest is automatic. You can also use your Audyssey measurements for a quick result.

[@Jonesy1993]

Automatic, assuming I still name the other measurements the correct channel. I found It quicker before to run the playlist in VLC in the correct order ie c, fl, fr … and let Rew auto number them 1, 2 ,3 … in position A, B, C … all I had to do is press control + m and enter after each measurement and it’s ready to take the next. And after I cross correlation and vector average the measurements together I would then give it the correct channel name. Any way this is a feature request from rew not anything you have control over. But I’ll give it ago now just naming them as I go and let neuron do the rest. Another question though last version went to 200hz which can be changed up to 1000hz is this the same?

[@scott-richardson]

Next question - dumb one again - but obviously my Marantz needs to be 'on the same network' as the computer for the script to find the processor and get the .avr file?

[@carstenc3582]

Okay... If they are not in the same network, why should your computer connect to the avr at all? You cannot connect to desktop pc at Microsoft also... obviously, I did not get the question. Can you say it in other words? Please tell us which Model you have because only because it is Denon or Marantz it does not work for all models.

[@JoeLyce]

A little feedback from my end: I tested now both the A1 Evo Mastro and Neuron. Everything went smoothly, no holdups or errors - except for a false positive in phase detection with Neuron. It flagged one of my surround speakers with a “Speaker SRA seems to be out of phase” warning. I’ve checked the cabling, and it’s correct (though I didn’t do the battery test). The option to disable speaker inversion was really useful. Also, I like how informative your script is throughout the process. I based my tests on a fairly new .ady file taken with the Audyssey mic that came with my Cinema 40. While Maestro gave me an immediate improvement, Neuron felt like it lacked bass, which I’ve heard others mention too. I think that might come down to subjective perception, since I’m used to having DynamicEQ turned on. As you suggested in an earlier comment, I’ll probably need to remeasure, this time using my UMIK and following your Nexus guide. Ah, and final sub volume was set to +7,5 dB. Any plans on an option for DynamicEQ in Nexus, too?

[@ocaudiophile]

Thanks for the feedback. You should experience with steeper target curves if bass is lacking and/or different "subwoofer target fill" values. Also, if your speakers qualify, LFE + Main mode will give a much richer bass most of the time. DEQ will be coming to Neuron in a more sophisticated manner with the help of odd.wtf but I need more time.

[@JoeLyce]

​@@ocaudiophile Thanks! Yes, LFE+Main is definitely possible with my KEF floorstanders - they’re pretty capable. Until now, though, I’ve stuck to just using LFE with a crossover at 80-90 Hz. But I noticed the crossovers in Neuron are set quite high at 150 Hz, so I’ll experiment a bit more with LFE+Main - and of course different target curves. Was about to ask if you could point out a steeper curve from you library, but then I saw the “Compare Tarved Cruves.mdat” - you got it all covered, man!! Looking forward to DEQ, but no rush - there’s plenty to tweak and play around with in the meantime! 😊

[@JoeLyce]

Hi. A lot to gain with different target curves. More bass now! Thanks. But I wonder, do you have any explanation why Neuron detects one of my surround speakers out of phase ("Speaker SRA seems to be out of phase!") - have you seen a lot of these actual false positives? (double checked, the connections are good)

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!

Is that correct? It is important to say that the subwoofer is definitely not 6.0m away from me! The 3.85m was more correct. The other distance values ​​for the other speakers were only changed minimally after optimization.

With the adjustment its better but not as perfect as sub by itself. But I still have to test if it also sounds better or its just better looking in REW 😆 Also on my PC REW seems to have quite a performance problem with many measuremenst open (> 100) which caused API errors.

New A1 Evo Neuron Release - Preview v1.4 (30 Dec 2024 23:00 CET) • odd.wtf upgraded to v0.8-8, introducing a new power command to turn the receiver ON and OFF. • Consolidated multiple processes into oddMenu.bat script for easier usage (courtesy of Music_Cat) • Calibration target curve and other user options are now saved in the .oca file. While they can currently be viewed with a JSON editor, they will be displayed during file transfer in the next odd update. • Resolved a bug that caused distance limit issues in certain setups. This fix significantly improves bass response for affected configurations. • If one speaker in a pair is assigned a significantly higher crossover frequency, it will now be adjusted closer to the lower crossover frequency of its pair to avoid bass localization • Recalibrated crossover frequencies for better alignment with filter resolution in MultEQ XT systems • Addressed an issue with the "CH" speaker in Auro 3D setups. • Minor UI improvements • New Options added: o Disable Speaker Inversion: Indicative results without altering polarity. o Force Large Fronts: Allows front speakers to operate in large/full range LFE + Main mode (if they are large enough). Other speakers/pairs will only be evaluated for full range if front mains are set to large This version is free of bugs (for a preview) and I believe represents the potential of the new Neuron!
