Audyssey One - Nexus (Automated hi-res Denon/Marantz calibration with REW/Umik-1/2)

Thanks for A1 Evo btw. This tool saved me from spending a fortune on an amp with X32 or Dirac, while delivering room correction far superior to the first built-in calibrations I tried.

Thanks.

So if I understand correctly, DynamicEQ should remain off in all cases, right? 'Reference' now kinda acts like DynamicEQ on, and 'Flat' like DynamicEQ off?

So I don't need to manually change the polarity behind my subwoofer? Sorry for my bad English.

P.S. Thanks for A1 Evo. This tool saved me from spending a fortune on an amp with X32 or Dirac, while delivering sound quality far superior to the first built-in calibrations I tried.

No. Neuron takes care of that. Be sure to retake at least 7 point measurements (MLP + 6 around it) using the Audyssey mic connected to the AVR, but with the odd.wtf menu bat, not with the useless and buggy app. It makes a huge difference and can sound better than Dirac + DLBC if done right.

That's exactly what I did with 9 point measurements before seeing this polarity warning message. ;)

Just two days ago, I still believed buying a Umik-1 was absolutely necessary to use Neuron, so I had stuck with the old A1 Evo version. That's what I understood from watching the video. Fortunately, I later read the PDF explaining that we could use the amplifier's included microphone along with odd_menu.bat.
 
I redid the calibration with 3.1 instead of 2.4 with the same 12 point measurement I did diligently for reuse.
3.1 increases low end precision by a very noticable margin again.

I still stick to eAPO adaptive loudness via windows but I will try out the new Reference calibration soon. I always looked for an ISO 226 adaptive loudness. eAPO just boost highs and lows. Though it does so smartly, ISO226 is a little more complex.
 
"To apply them, run the provided sendFilters_lowVolume executable in the same folder as your .oca file. Versions are included for both Windows and macOS".

Uh, is it just me or isn't there any file named like this in the folders? I only can find the usual odd.wtf and "sendAllSettingsatOnce"

Edit!
Alright "sendAllSettingsatOnce.exe" does the thing:
Audyssey 'Reference' and 'Flat' modes are loaded with different A1 Evo filters.
Use 'Flat' mode for regular volume levels and 'Reference' mode for low volumes.
Both modes are calibrated to be used with Dynamic EQ OFF!

There seems to be a new A1 Evo version called Acoustica:

A1 Evo Acoustica - Google Drive

drive.google.com drive.google.com


It's not an HTML script, it's an executable file. Give it a try.

Doesn't seem to be release ready, seems to search on a weird IP (personal local stuff from OCAs home network?)

Where is there an overview?

I've downloaded the MacOS ARM version and it was able to connect to my Denons and generate config files. So it appears to be working for me, albeit from the command line in a terminal window. Just need to figure out the big picture...

Edit: Never mind, found the kickoff thread on AVS. Haven't followed the Evo saga too much after being very happy with Evo Meastro MJ when it matured. It seems Serko wanted to retain better control of his work by generating a compiled executable. That makes complete sense to me. This being version 1.0 I expect there will be a few revisions before the dust settles.

Same result. I even disabled all other network adapters like bluetooth and VPN that may be rerouting or confusing the network stack.
 
I tried the ISO226:2003 Audyssey REFERENCE setting in movies just now and it's pretty good, but I would love a option with reduced or removed mid-high and high frequency boosts since these are pretty strong currently. Even if it may be accurate ISO 223:2006, it's still kind of harsh, or just based on a lower listening level than the one I use.

Currently in Evo 3.1 :
FLAT + Harman 10dB curve = okayish but too little low end for movies
REFERENCE + Harman 6dB curve = great low end, but highs and mid-high a littel too spicy in movies
 
hey guys,

would be great if someone could help me out here...

I used @OCA s Audyssey methods/scripts in earlier versions already. Now I'd like to try out the recent ones, but I'm running a 7.0 setup without subs and I've read that one needs at least one sub for them to work.
  • Is that correct?
  • If so, is there any way around that?
  • If not, what's the latest version I can use without subs?

thanks,
Times
 
Haven’t had a ton of time to test over Easter weekend but so far Acoustica is a solid iteration over Neuron and without a doubt the best I’ve ever heard my setup. Only really leaves room to experiment with target curves, the script itself does exactly what it says on the box.
If you have compatible Denon/Marantz AVR, I compel the reader to try it.

Attached is my current and fairly neutral target curve of choice.

Serko, the MacOS readme really isn't required. The first time you try to run the executable you get the warning and refusal. You can then go to Settings:privacy and Security and the program will be listed, you can then give permission from there to allow execution.

But thanks for being thoughtful! Will give this a try very soon. You've come a long way!
 
@OCA
Thanks for another release :)
Just quickly tested with old rew measurements (only MLP) I had around from Nexus times, and two weird things are happening. First it detects all speakers (except for SW) are polarity inverted, and then it's setting front speakers to full range, rather than setting it's calculated 40hz crossover, meaning sub isn't activated unless the crossover is manually set in the AVR. Tried forcing minimum crossovers to 60hz yet same happens.
This is running A1 Evo Accoustica on Mac ARM and Denon x3800h.
As for allowing the software to run, @middlemarch method worked and it is indeed easier.
Let me know if you'd rather have these sort of comments on a platform other than ASR.

When all speakers need inversion, it should warn that none are going to be inverted? Pls share your mdat and . avr and let me check

You're right it does mention "Nothing wrong with your speaker polarities, all speakers may seem inverted when phase inversion is elsewhere in the system!", missed it.
Mdat + avr here:
Thank you!

Your fronts come up crossed over at 40Hz and that reflectes correctly to the .oca calibration file. Nothing is set to Large:

If the transfer doesn't seem to carry those XOs over to the AVR, it could be a preset issue or you are checking from WEB UI which has many bugs, only trust AVR set up menu for double checking settings.

Thank you for checking and reviewing the data. It did transfer the fronts as large to the AVR, and I've checked it on the AVR itself, not on the Web UI, as you've mentioned in the video. So far, I've manually adjusted the fronts to small and set the XO accordingly.
Will try to spend more time over the weekend making new measurements and resetting the AVR to double check if it works.
Thanks again for all your work!
