The script only seems to run when there is an active internet connection. Otherwise it gets stuck analyzing the FL speaker. If I connect the network cable it runs normally. Is this an error in the script?

Hi, first of all, happy new year, and thank you for the amazing tool! However, I am facing an issue. I conducted 14 measurements, but now Neuron seems to have a problem.

I can't seem to get past"Generate configuration from existing setup". Originally the screen showed " press any button to continue" but now the black screen flickers for a brief second and then goes away. Ant ideas?

Jetzt hat es bei mir endlich auch geklappt! Wirklich tolle Arbeit! So macht Filme anschauen noch mehr spaß. Macht weiter so, vielen Dank ❤🎉❤

Good Morning all. Is there any way to use this nice script with a system without a sub ?? I get an error "you need a sub" !!

Again thanks for your great work. tried 1.4. Can I still set the Crossoverpoints in the script? I also get an out of boundary error for one pair. No idea why. still sounds great

Merci !

Hello and thank you for this incredible and in-depth explanation. I will try it in my new project studio. I wanted to ask you if, in your book, there’s any upside or downside of mixing different sized subs (12” vs 15”). Is there anything to do different than what you’ve demonstrated? Should I sell one vs the other, and why? Thanks again!!

OCA I am very sorry to ask before reading every question already (I tried) - I have a miniDSP Flex 2 subs connected to it directly, and 2 active monitors plugged into it directly. No AVR. When I create the coefficients EQ at the end here, which subwoofer do I upload it to in the PEQ screen of the miniDSP config? Sub 1, Sub 2 or both? Also I assume I need to put in the sub delay into nominally the sub I chose to perform the cross correlation.

When I click to open "Generate configuration file from your existing setup", nothing happens. Am I missing something?

I'm stuck at the API setting, the help file says I need a pro license? Am I missing something?

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 :-)

Hi, OCA, maybe you can please tell me why the dialogues from the central channel are hard to hear?) I have to constantly turn up the settings to almost +10 dB,

1.4 - doesn't report that my speakers are out of phase anymore. I had clicked the ignore out of phase option but maybe something in the algorithm changed? A few questions for when you have time OCA. 1 - I thought the sub was running a little too hot at +8.5db under 1.3 so manually set to +6.5db via the web control. Ran 1.4, transferred everything to the receiver expecting the +8.5db as per the 1.4 log, but the receiver reports +6.5db still. Everything else appears to match the log, so was curious why it had not changed the sub setting. 2 - My front 3 channels give this message - required several additional attempts to be properly aligned to MLP due to strong HF reflection content in its IR! Could you possibly explain what this is please and how I might mitigate this if it's an issue? Thanks again - still can't quite believe what you've achieved here and your work over the Christmas period has been unexpected - 4 releases in less than a week.

I think in v1.4 the Force Large Fronts option is not working. It's showing in the log that the option is on, but the generated calibration file sets Small Fronts

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

Hi OCA, hi people, if you measure with the AISO4ALL and the provided sweeps, do you use the +10db SW sweep or the +0 dB SW sweep for the measurement? Thanks in advance. Very much appreciated, due to I cannot understand the logic behind the LFE channel...

v1.2 SW effect is very nice, you can feel it, the couch is shaking, soundstage is detailed v1.3 SW effect, the couch is not shaking anymore, soundstage is detailed but somehow feels to be more in the back than 1.2 v1.4 SRA is now detected as inverted and it is not. this is the first version that detects a speaker inverted - false. FR and FL are set to 150hz while with 1.3 are Main + LFE, Pair efficiency is 60% while with 1.3 are at 100%. bass it's a bit "boomy", feels not clear, not as deep as v1.2 soundstage if compared to 1.2 and 1.3 feel in the middle, for my tase i like the 1.2 stage more. I feel like i missed something, what's with the: "Atmos measurment sweeps for REW" "Start automated measurement process" "Set your receiver into REW measurement mode" I'm guessing the second part from the Nexus video applies here? Do i need a UMIK1 mic? or can i use the acm1hb mic? how?

Appreciate your efforts, thank you. We know EQ should be done below transition but with this method it is ok to do it full range?

Danke!

What's the difference between Neuron, Nexus, Maestro, etc? I'm confused between all the different versions.

A1 Evo Nexus user….No matter if I use Evo,Nexus,Maestro etc… I always get this message saying Center speaker distance was not found in the file and the programme sets that in the approx….however Evo,Maestro,Nexus or which ever I use that scripts processes everything successfully…….but it is the Center speaker distance not found phenomenon that is currently pissing me off….

Extract measurements fails with MUltiEQ-X 1.8.873.0 file: "A1 Evo Neuron Preview 1.4.html:1679 Uncaught (in promise) TypeError: Cannot destructure property '_measurements' of 'jData' as it is undefined. at Object.mqx (A1 Evo Neuron Preview 1.4.html:1679:31) at processMeasurements (A1 Evo Neuron Preview 1.4.html:1740:39) at extractMeasurements (A1 Evo Neuron Preview 1.4.html:1744:9)"

Just have a question about my centre. Fronts and surrounds are all within normal XO but my centre is always at 250hz... I've done 3 measurements with the same outcome and you can sound the lack of bass in male voices.

A1 EVO MJ user, but I decided to give this a try. Script can't find my Denon X4700H get error code 1 AVR is powered on and it on a different address space 192.168.5.x vs laptop 192.168.0.x I did try again w/ laptop in same network. Currently there are no network segmentation in place that prevents access. My laptop can ping the AVR.

Just tested now. Is it normal that , after uploaded the calibration file into the AVR, ... Audyssey is set to "flat"? thank you

HI! I always get these results for SLA and SLR 10:47:58 PM [INFORMATION] Speaker SLA valid frequencies >> 10:48:02 PM [INFORMATION] Speaker SRA valid frequencies >> 10:48:06 PM [INFORMATION] Individual best crossover frequencies > 10:48:06 PM [INFORMATION] Speaker SLA: 100Hz, efficiency: -29.43% 10:48:06 PM [INFORMATION] Speaker SRA: 100Hz, efficiency: -20.74% Thats is, nothing more in the log. Both speakers are measured multiple times with the same result. What could be the problem?

Hi @ocaaudiophile, I am at a loss here. I own a Denon X3600H and have two subwoofers connected to it. Running a calibration using MultEQ just measures both subs as one. When I upload the file to A1 Evo Neuron it gives me the following error: 21:15:02 [WARNING!] Imported measurements currently in REW are missing measurements for some of 2 subwoofers in your system! 21:15:02 [WARNING!] Try manually measuring each of your subwoofers with REW and a calibration microphone since your receiver is not compatibe with 'directional bass' mode. 21:15:02 [ERROR!] A1 Evo Neuron cannot optimize your system without individual measurements for each subwoofer! Do you or any of the readers know what I could do to fix this?

i think i missed something, what's with the bat scripts in regards to measuring?

I am stuck at transferring as the bat program to transfer is not working on my macbook is there anyway i can generate .ady and use multieqXT to transfer to my X1800h

Wow, this has taken things to the next level. The bass is so much more present than before. And it’s absolutely brilliant that I can now adjust the bass volume myself. Outstanding work! Thank you so much for this powerful update. Once again, you’ve done an amazing job. Wishing you a great start to the new year and sending my best regards from Berlin, Germany 😊.

Hi Great work again. when setting the receiver to rew measurement mode i need to change the speaker layout to 2 subwoofers? i kept it at one then changed cables for the measurements. only Neuron tells me that SW2 is wrong? I changed my receiver to 2 subs generated a new configuration and now it works. Is this the right way todo it? Thanks for everything

Thanks

Is the MultEQ only device incompatibility only with transferring the files to the AVR? If I manually put in the settings into the AVR will that work?

Hy Oca, just to ensure: Is there allready a solution for that transfer problem (Code1) ?.. i mean with multi eq 32. I tried to use version 1.3 and the latest odd.wtf but its not working. The batch-file to get the receiver configuration works just fine, also everything else...but not the transfer back to receiver. You did a great work to the community so thx for that. I cannot wait to see the results of Neuron. Greetz

Ran 1.3 got it all working and sounds phenomenal best yet. One question though the script runs and says forcing LFE/main mode because of. Significant boundary differences with Left and right but when it loads it doesn’t load LFE/main. Is that correct?

How do I know, which is the "right" target curve?

Feedback on version 1.3 Version 1.0 bass much too loud Version 1.1 bass too quiet Version 1.2 bass a little too quiet by hand +3dB for action films. Version 1.3 bass a little too loud. by hand -2dB Version 1.3 sounds very good overall though. You can adjust the bass manually to suit your taste. Great work! But my heart bleeds because my 4000 Euro floorstanding speakers are set to 250Hz XO. Can't you add an option to the script that lets you choose whether the front speakers are running full range? According to the log file, that's what it looks like.

HI OCA. After using the version 1.3, large difference in settings then with Nexus. No lisening test yet, wanted to catch your opinion: - Audyssey used "Flat" as preset, but i had "Reference" before. Does it take the preset that was set in the AVR, or from the reference ady file? - LFE+Main with 150hz - Front Speakers are large, rest is small (Atmos setup) - Fronts with 120hz, rest with 80 to 100hz - Subwoofer now level on 0db. Difference in Crossover is very different by my fronts (left one is in the corner, both in front of a wall). So i think it makes sense?

Ok NOW we are talking! this v1.3, even though it still chooses 250hz for my front and center crossovers, actually sounds a LOT better than the other versions.

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?

Great stuff!, BUT I am guessing I am pretty much screwed with miniDSP 1024 taps per channel!

Multi sub works great - but if I tick "Avoid sub polarity inversion" then it forces the mains to large. I have tried "FL": [80], //Left & Right pair and also Force small fronts If selected, front speakers will NOT be set to 'Large / Full range.' but it still sets the mains to large. Problem is it either forced me to have to invert 2 of the subs (which I would rather not to have to do physically as this means I can't switch profiles as easily) or run the mains as large (I would like them set to 80hz but you have advised that it should be done in the script) Any Ideas?

Quick question, what does it mean when you set speakers to full range with a crossover at 150hz with lfe+main active 😅

This old retired FORTRAN programmer was thinking if could make a version where the script knows that the subwoofer sweeps come from MiniDSP2x4, for example, and @the end would provide all the filters for both the MiniDSP and for the AVR. My 2¢.

Do you recommend using max boost? or does it make the sound worse?

Hey OCA, nice vid as usual! Can you drop the track ID for the piano piece at the end?

Any chance for a dirac version of rhis?

In the video you are using 256kMeasSweep_0_to_24000_0_dBFS_48k_Float_L_refR, but in the Drive folder we got 256kMeasSweep_0_to_24000_-12_dBFS_48k_Float_R_refL. It's -12dBFS and FloatR_refL, not 0dBFS and FloatL_refR. Can you help me with this problem?

Hey, 1.3 still Sets my sub distance to 0.00m and +8dB, downloaded the latest Version. 1.2 Leveled it to 1.5 dB
