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

Unleash the Commish may use out-of-spec distance values up to 7.35m instead of 6.0m, which may or may not work. You must avoid checking the distance results in the AVR setup, including the web interface or app, as it may get them messed up if they do not comply with the max distance of 6.0m.

Correct, in essence.

  1. The original version (A1 / Evo) used the Audyssey setup process (which EVERYONE with a Denon / Marantz receiver has access to) to run the sweeps and create the .ADY file, which is then processed using the script + REW to calculate levels / distances / crossovers / EQ, which are then stored in the .ADY file and uploaded to the receiver using the iOS MultEQ app.
  2. The latest version (Nexus) follows the same process but uses external (read: longer, more accurate) sweeps and REW + a calibrated mic to create the measurements. Once the measurements are created, the process is basically the same; i.e., the script drives REW via API to do the calculations, creates the .ADY file, which is uploaded to the receiver using MultEQ again.
A1 / Evo is virtually fool-proof to anyone with a minimal knowledge of how to upload / download files, while Nexus requires a bit of additional knowledge / fiddling but the results are a bit better because you're starting with more accurate measurements. OCA has also added some updated logic to the script which he plans to retrofit to EVO after the dust settles from Nexus.

I've bought a licence for the PC multeq-x app, but i havent registered it yet. Ive had it a couple years when i bought it on sale on windows store. Are there any benefits of me using this full on pc app vs trying to get a refund and getting the 20 usd app? are there any benefits i will have from the pc app? will the pc app work with audyssey one nexus?

The PC app is IMO completely supplanted by various versions of A1. It's a suite for adjusting the target curve, which is just one small step in REW with A1.

If you want to sit and play with the curves the PC app is just more resolution and control than the neutered $20 mobile app. Since you've not been doing that, best to ditch it for the refund, though I don't see any likelihood getting a refund outside the first couple weeks.

The app is not going to interact with A1 Nexus.

can I use the pc app instead of the mobile phone one? In case I cannot get a refund? I think it was like £125 or something for it.

You don't need either, A1 Evo can communicate with your receiver without them, even take its own measurements using your AVR and Audyssey mic.

Hi OCA, how do you take measurements with Neuron? I did not notice this functionality before?

Also how do you use sendFilters_lowVolume_MacM?
 
It's one of the many features of odd.wtf program which runs from the command prompt but you can also use odd_menu.bat below (option 5)

There's a similar batch file for Macs along with instructions in the video folder.

I have replaced sendFilters_lowVolume with 'sendAllSettings' this morning. Just save it in the same folder as your .oca calibration file and run. It now sends both normal and low volume listening filters at once, can also select between presets.

crikey that's pretty cool. I haven't had time to get round to calibrating the system, but I do own a UMIK-1 from when I had an Arcam AVR 850 and AV 860. Is calibration with a UMIK-1 covered in one of your vid tutorials?

I had explained it in detail in the Nexus video (which worked only with REW measurements), didn't go through that again in Neuron video. Dolby Atmos REW sweeps you will need are available in both video folders.
 
If you don't have experience taking measurements with REW, I would suggest to start with Neuron's own measurement tool. You can use as many mic positions and as many repeats in the same mic position as you like (not limited to 8 as the default Audyssey), it's quick, easy and standard Audyssey mic performs very close to Umik-1 especially in the most important bass region. Many people have achieved exceptional results. REW can get more accurate readings of course but too many things can go wrong with played Atmos sweeps and LFE levels etc for someone without experience for little gain.
 
Hello OCA. Will EVO Neuron calibration also work with older Marantz receivers such as SR7009? And does it work for both Atmos and Auro 3d speaker layouts?

Hi OCA!
Sorry for “hijacking” this thread, but it turns out your A1 Evo probably saved me a ton of hassle—both in terms of time and cost.

The Current Dilemma in the Audio Market​


It's nearly impossible to find a product that checks all of these boxes:
  • Affordable price
  • Good audio performance
  • Dirac support
  • Balanced outputs
  • Dolby/DTS decoding

No matter where you look, at least one of those key features is either missing or poorly implemented. The situation got even worse with the direction the Sound United Group is heading—looks like we may never see another high-quality Denon AVR again. I was seriously close to just keeping my X3700 and settling for Audyssey’s subpar multi-sub integration.

And Then I Remembered Your Tool…​

As a last resort, I gave your open-source tool another try after repositioning my subwoofers.

It. Is. PERFECT.

I can't localize either of the two subs anymore—they blend seamlessly with the mains. The cohesion is just so good, I genuinely feel like I should have paid for this. And I mean that seriously—please send me a PayPal link.

The Impact​

Thanks to your work, I can now patiently wait for a future “do-it-all” pre-pro to hit the market in the coming years. Until then, my X3700 is going strong—and it’s all thanks to you.

Funny thing is, I remember being the biggest skeptic at first!

So again: thank you. Outstanding work.
 
@OCA

Could you technically use the post processed REW results for other devices like MiniDSP? Or do the calculations already include the Audyssey quirks? Or are the quirk optimizations only applied when transferring the .oca file to the receiver?

While it's possible to generate an xml file that MiniDSP can load directly, it's quite a bit of tedious work that I don't have time for (or enough demand per se). I am working on a multiple sub + speakers optimizer though (a standalone project) and that might have a MiniDSP compatible output.

I recommend trying Neuron v3.1, which can now load DEQ-like (ISO 226 equal-loudness) filters into the reference mode slot.

Oh my god, now I've got something to play around this evening! I still had 2.4.

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.

Yes. You can still experiment with a flat target curve and load it into the second preset. Then, go to the speaker levels and reduce all back/rear channels by 6dB, and then activate DEQ. It should work with the flat mode. But the reference is just as good.
