A1 Evo Neuron

[@ocaudiophile]

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! See you next year! OCA @ocaudiophile

Version 1.0 took out all the bass from my system (sub level was set to +1), but version 1.1 takes it out even further and sets it to -9 making it sound very anemic. Merry Christmas!!

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.

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?

[@johnrsu1273]

Out of curiosity, why do you prefer using the app? The new Neuron method is so much more streamlined and makes it feel "proper" instead of a hack.

App cannot send the filters Neuron produces. They include phase correction which Audyssey cannot do!

Monumental. The mojo is back, better than ever! Thanks man, never ever sounded better. I bow before your greatness - good work. Feature Request 1) you should say that (when everything else is automatized) if LFE+main is used, that it needs to be configured manually in the AVR. Feature Request 2) would be great if both slots can be used instead the slot1 fixed but just a nice to have. Thanks and greetings to Aaron - the generation and transfer of the file now works with the x4800h.

[@ocaudiophile]

Rock on!

[@ocaudiophile]

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.

[@carstenc3582]

Okay that is cool! Why not telling it more obvious - perhaps in the filename „transfer file to current Preset“ or somethikg like that? It’s a cool feature, thanks! I have the current x4800h with current firmware incorporating Dirac Live, Dirac Live Bass Control (Full Range) and xt32.

I read the Denon manual again. If the front speakers are set to large, all frequencies are passed on to the speaker. The Front Crossover 200Hz setting confused me. This means that the subwoofer also reproduces all frequencies from the front speakers below 200Hz. So everything is fine. Great work, version 1.4 sounds fantastic :-)

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?

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

[@SeanGreensmith-i3p]

I’m not going to look at the crossovers or anything once I’ve rerun Neuron.

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.

[@mladia]

Can you give us a step by step on how to get it to the AVR? I used my ady file. Went through optimization and got the file result but not able to transfer to AVR. Honestly, I miss the ady file creation that you just kick into the AVR. But Thank you very much for the update!

[@ocaudiophile]

There will be a tutorial on all features and tips with odd.wtf

[@RalfB.-oz9yx]

I have now compared the old EVO with the Neuron 1.0 and 1.1. The old EVO has the best bass settings. No adjustment necessary. The Neuron 1.0 has the bass set much too loud (+8dB). The Neuron 1.1 has the bass set too quietly. I had to correct it from -1.5dB to +2dB to get the same result as with the old EVO. But the surround effects sound better with the Neuron versions! Clearer and more precise. Great work! What surprises me is that Neuron sets my small ceiling speakers to a crossover frequency of 100Hz. According to the manufacturer, they should be separated at 150Hz. Can I set them to 150Hz by hand?

[@ocaudiophile]

No unfortunately, XOs should be changed from inside the script in the preview version. Customization will be added eventually.

[@RalfB.-oz9yx]

@@ocaudiophile I think it would be safer if you could limit the crossover frequency of each speaker manually so that small speakers cannot be damaged at high volume.

[@jamesbeshero2029]

Thansk for all your work OCA. Can this be run with just the ady files taken with teh pack-in mic and MultEq app like Meastro and EVO or will this require independent REW measurements with a umik or similar device like Nexus? Ive stopped at Meastro as I dont have that required equip (umik) to use Nexus but was curious about this version?

[@627viewer]

I used my old ady file, you have the choice on using that or running the programme with new rew sweeps, nexus and this work with the standard audyssey mic

[@jamesbeshero2029]

@ right on. I don’t have any REW sweeps because I never did nexus. Stopped at Maestro. I got an error when I tried to use my ady about MLP measurements so I presume I need some data from manual REW measurements. Doesn’t seem as easy as just using my old audyseey ady file alone, unless I’m mistaken.

[@627viewer]

@@jamesbeshero2029 I did not do the rew sweeps either. I used the same ady file I have used for evo, neuron done all the adjustments in the avr for me rather than telling me to make adjustments, I found it allot quicker to do than a1 original and evo, maybe a fresh install of rew will work as shown in the video, I reinstalled rew before running the script.

When taking the REW measurements, should I set my AVR so that all the speakers are full range? I've got a new Marantz Cinema 40 (upgraded from a Denon 3600H) and I haven't ran Audyssey yet as I want to use A1 with REW + my UMIK1 mic. The Cinema 40 has set the speaker crossovers to 80hz by default. Also is there any reason to run the Atmos sweeps with a standard 5.1 setup?

[@ocaudiophile]

No reason to run Atmos sweeps with 5.1, just go with REW's internal sweeps. The odd.wtf file can set your AVR to REW measurement mode correctly but you will need to wait for the next video for that. Aiming to release it very soon. If you don't want to wait, all speakers must be full range, sub must be in LFE mode with LPF for LFE set to 250Hz and don't use WEB UI for these settings, they have a bug, do it from the AVR menu.

Hi Serko, my English is ridiculous and I've seen the video on my mobile. Are you mentioning a possible +5 DB increase in the eq of the sw by Neuron? That's a paradigm shift. Tomorrow I'll start my round of tests with a sw input through deinidsp and Mso, then I'll try individual sw and I'm very curious to know how the crossing of my openbaffle front speakers crossed by Nexus at 200 hz is resolved. How far away is when you made me a custom script, when you started this challenge in a spreadsheet. Thanks for the fun, if the sound improves from the current one it will be a miracle.

Strange. For my setup, neuron pushes every channel to 40 HZ. So no bass felt from my two subwoofers. But it was not the case with EVo and Nexus before. Hope this will be corrected soon.

[@carstenc3582]

Dear OCA, thanks for your work in recent hours. I have switched back to v1.0 because in v1.1 and 1.2 no boost in the frequency response is Added and in my non-Standard room it sounds much beefier with 1.0. additionally, the +10 dB slide shows only +5dB. Is there any chance to force the script to try to not just lower some dips by 2 dB like in the current version?

[@ocaudiophile]

I am aware v1.2 have issues and 1.1 removed some of the magic from of 1.0. Not easy to fit a one for all algorithm but I know Neuron is there just needs a bit more focus from my side. Festive period doesn't help, can't properly concentrate on it long enough. Stick with me, this will all end very well.

Whenever I run the 'transfer to receiver', everything goes over except for speaker levels. Marantz SR6013. I can manually set them, but it seems the transferred calibration won't set them automatically for me. Any advice? Edit: So it seems the web ui is actually freaking out with the receiver and not showing properly set levels. When viewing the levels in the receiver menu, it’s all set correctly. Strange. Maybe the config pushed to the receiver is too powerful for the web ui to resolve.

[@timm-1138]

Thanks again for this great update and all the effort and time spent :D I could calculate a configuration that sounds great using the Neuron target curve. However when switching to another target curve, like e.g. not dr.toole, and using the exact same measurements I get the 250Hz XO frequencies for Front and Center (also the for the atmos speakers the XO change). Is this expected?

[@ocaudiophile]

Yes, Neuron bases its XO settings on the target curve which is how it should be.

[@timm-1138]

@@ocaudiophile OK, just surprised by the big difference between 60 Hz (Neuron target curve) and 250 Hz (not dr toole)

[@ocaudiophile]

These two curves have about 4dB difference in bass, not all speakers can draw that response comfortably. Having said that, I will make it a bit harder (it's already exponentially harder to go over 120Hz) to go beyond 150Hz in the next update.

[@ThomasLeeb-u2t]

Hi Oca, that´s absolutely great and a huge step for easy usage, cannot wait to try it:) I´d like to ask two questions. does the script consider the speaker capabilties, e.g. via distortion measurement, in any way? In my experience so fart with all versions the script produced cross over frequency e.g 40 Hertz also for small speakers with 5" drivers. In the frequency measurment alone that might be right, but overall that does not make much sense and small speakers need to be crossed way higher. So a more flexible cross over would be highly beneficial.... 2nd question would be if the script can handle a combination of MLP single measurements for timing, phase etc combined with moving mic measure without phase information. That would save alot of time as not multiple single measures need to be taken. All relevant information for distance , delay etc are already in the first MLP Master measurement.. Thanx alot for all your effort and dedication!!

[@ocaudiophile]

Crossovers are set taking into consideration wall/room gains and relevant bass roll offs in Neuron. If both speakers get the best scores from same or nearby frequencies, there's nothing to worry about. If they are crossed way too high though (ie 180Hz and above) , it usually points to a speaker placement problem or a measurement related error. No way to combine MMM with sweeps because MMM measurements do not have phase information. Neuron differently previous versions, applies a very smart algorithm to average multiple mic positions which give similar results to MMM especially for subs.

[@ThomasLeeb-u2t]

@@ocaudiophile Hi, ok I get it with the MMM measurement, but not with the crossover. Frequency response and roll off might all be fine, but this does not consider any speaker SPL capabilities. Imagine having a small speaker with 5 inch woofer which can play down to 40 Hertz , with help of wall / room gain or whatever and combining this with a way more powerful sub or a sub that can play way louder in the range to 80 or 100 Hertz. So with the forced low crossover you limit the capabilities of your speakers dramatically (spl, distortion, etc.) and might even damage them. So consideration of speaker capabilities is a must from my point of view

[@spatel30]

@ocaudiophile, With A1 nexus, the script prompts whether the measurements were taken with DEQ on and at what level. I used DEQ while taking REW measurements for A1 Nexus. Is it okay to use the same REW measurements for Neuron? Or do you recommend taking REW measurements with DEQ off for calibration with neuron script?

[@ocaudiophile]

People did it with success but I would suggest to use your old AUdyssey measurements rather than using DEQ on measurements until you take new REW measurements with DEQ off.

In your AVR, the subwoofer number must have been set to 2, you will need to change it to 1 before you generate .avr file The odd.wtf measurement process will generate a .ady file from which you can extract measurements for REW with Neuron.
