Thanks ! There is a click on the right channel at 1mn54.26249s but it does not impact significantly (<0.1 dB) the result:
ADM: -502msec, 0,066dB (L), 0,101dB (R)..Corr Depth: 27,2 dB (L), 28,8 dB (R) Difference: -46.9 dBFS, -47.9 dBFS
I will put this one rather than your first test in the list of results.

Tests by SSL Alpha-Link MX 16-4 by Sankly and of the combination of the Motu 24-Ao and the Lynx Aurora 8 by leolycra added to the list.

AD-DA loops from this wav file evaluated by means of Audio DiffMaker.

'Difference' indicates RMS level figures measured in Wavelab from the difference file delivered by Audio DiffMaker.
'Difference*' indicates RMS level figures got from a difference file generated in Matlab after refining the time offset and gain figures provided by Audio DiffMaker in order to get the lowest difference level. Hence the 'Difference*' figures are lower than the 'Difference' figures.

Read also this about the test method.
See at the end of this post how to contribute to the test.

Unsynchronized mode. The DA and AD converters run each on its own clock. Measurement performed with sample rate drift correction activated in Audio DiffMaker and limited to the first half of the sample. Because the RMS level of this first half is 1 dB lower than the RMS level of the full-size sample, one must increase the difference RMS level figures by 1 dB for comparison with the synchronized mode.

Thanks again for all your work in maintaining this thread, didier. It's appreciated!

Anyone have access to the new Audient id14 or the theunderbolt Zoom TACs? I've been holding out for the focusrite claretts, but I'm not sure how much longer I can wait.

Test of the Lynx Hilo by schizoide on the French forum Pragmatic Audio:

ADM: -1,86msec, 0,495dB (L), 0,494dB (R)..Corr Depth: 56,5 dB (L), 57,6 dB (R) Difference: -69.2 dBFS, -68.6 dBFS
Matlab: -1.85944 ms 0.492 dB (L) 0.492 dB (R) Difference: -72.3 dBFS, -71.2 dBFS
These resullts are much better than the ones from both other Hilo units already tested here. schizoide's unit was bought new from Thomann at the beginning of this month.

List of resuls updated.

Test of the Audient iD-22 by Hardtailed:
ADM -3,676msec, -0,089dB (L), -0,091dB (R)..Corr Depth: 31,1 dB (L), 32,7 dB (R)

ADM difference file measured in Wavelab: -56.2 dBFS (L), -56.8 dBFS (R)
Difference between the original and the time offset and gain compensated copy from ADM: -49.8 dBFS (L), -50.1 dBFS (R)
Both difference levels should be equal !
Left channel of the difference generated in Wavelab with the gain correction from ADM -0.089 dB and three different values of the time offset: -3.6755 ms, -3.6760 ms, -3.6765 ms, all possibly written -3.676 ms when limited to 3 figures after the decimal mark:
-3.6755 ms ---> -49.5 dBFS
-3.6760 ms ---> -50.2 dBFS
-3.6765 ms ---> -50.8 dBFS
Hence the level of the ADM difference 'iD22-Original2.wav' is not coherent with the time offset and gain values specified by ADM as an opposite to the corrected copy '[email protected]'.

Matlab search for the best correction:
-3.6777 ms, -0.089 dB (L), -0.091 dB (R), Difference: -51.6 dBFS (L), -52.4 dBFS (R)


Added to the list of results.

These results are identical within a few tenth of dB to the ones from the units tested by CoolColJ (-56,8 dBFS (L), -57,2 dBFS (R)) and sm5 (-56,5 dBFS (L), -56,4 dBFS (R) and -56,6 dBFS (L), -56,5 dBFS (R)). -59 dB Difference* figures were obtained by refining the measurement in Matlab and would be most likely obtained also from both these new loopback files.

Both theses tests and Audient iD22 ---> Behringer ADA8200 and Behringer ADA8200 ---> Audient iD22 tests by Hardtailed added to the list of results.

AD-DA loops from this wav file evaluated by means of Audio DiffMaker.

'Difference' indicates RMS level figures measured in Wavelab from the difference file delivered by Audio DiffMaker.
'Difference*' indicates RMS level figures got from a difference file generated in Matlab after refining the time offset and gain figures provided by Audio DiffMaker in order to get the lowest difference level. Hence the 'Difference*' figures are lower than the 'Difference' figures.

Read also this about the test method.
See at the end of this post how to contribute to the test.

Unsynchronized mode. The DA and AD converters run each on its own clock. Measurement performed with sample rate drift correction activated in Audio DiffMaker and limited to the first half of the sample. Because the RMS level of this first half is 1 dB lower than the RMS level of the full-size sample, one must increase the difference RMS level figures by 1 dB for comparison with the synchronized mode.

Please forgive my ignorance- I went through the first few pages and skipped to the end...I have a few questionsL

What do these results mean exactly? IOW,

What numbers should I be looking at to determine which converter is "better"?
(difference"

Do the test numbers equivocate to a better sound quality?

Making these assumptions, the MOTU 828mkII is supposed to sound better than the Lynx Aurora?

Thanks for any insight...

Yes, the lower the Difference is, the better.

I would say they are on par, the difference between the two results being quite small, around 2db.

I suggest you to listen to files, after having adjusted the volumes according to the results found, and do some A/B tests against the original.

Except if the Aurora has a superb clock and the Motu a crappy one? this tests ignores clocking difference, which is still part of the conversion quality. I take the test for what it is, a cool experiment. I'm glad my Konnect 48 is up top, + it's got a great anti-jitter clock.

But I have to say the DAD AX24 can't really be so average in real life...?!

No, ADM also takes clock issues into account. But this number is not written in this thread.
How strange that different recordings of several unit of the same type measure the same!...If the test was measuring "b$$$$$$it", it would not be so repeatable, no?

Ok, I think these tests mean something, some others think the contrary...no problem with that. Listening to files is also quite revealing and correlated to result numbers.

I compared an MOTU 828 to a RME ADI-8 about 10 years ago and it was a night and day difference in sound quality with the RME being much much better.

about the same- the stereo image is a little squeezed on the Motu mkII- the overall level was lower but I turned it up so there was no loudness advantage- the RME still seemed clearer to me. I have an Audiofire 12 and hate to say it but the highs sound a little harsh- not as crisp as others.

Right now I'm listening with old iphone earbuds through a Dell laptop soundcard but the sound is not bad at all.

FYI I did my own diffmaker test last night and came up with very close results to what;s posted here for AF12.

Thanks for all your hard work with this thread!

For each of the three copies, the best match to the original is achieved by means of a gain correction not exceeding 0.1 dB.

My monthly bump... hoping to see some results for Focusrite's new Clarett line.

I'm in a holding pattern, as I'm looking to replace my interface I sold last year (silver face Apollo). I need to downgrade a bit, as I can't afford $2000 USD like I did a few years back; as always, latency and quality are paramount, I/O not so much.

Loved my old Apollo, but I don't like being tied to latency-free monitoring via a specific app (i.e., UA Console). This is why the Apogee Ensemble (too expensive) and Focusrite Clarett are attractive... virtually latency-free in the DAW itself. I may just bite the bullet and opt for an Apollo Twin since I know and love the plugins and learn the console.

Two asynchronous tests from usernaim added to the list:
Musical Fidelity V-Link ---> Benchmark DAC1 ---> TC Electronic Konnekt 8
Lavry DA11 ---> Benchmark ADC1 (non USB, 2005) ---> Tascam US-366

AD-DA loops from this wav file evaluated by means of Audio DiffMaker.

'Difference' indicates RMS level figures measured in Wavelab from the difference file delivered by Audio DiffMaker.
'Difference*' indicates RMS level figures got from a difference file generated in Matlab after refining the time offset and gain figures provided by Audio DiffMaker in order to get the lowest difference level. Hence the 'Difference*' figures are lower than the 'Difference' figures.

Read also this about the test method.
See at the end of this post how to contribute to the test.

Unsynchronized mode. The DA and AD converters run each on its own clock. Measurement performed with sample rate drift correction activated in Audio DiffMaker and limited to the first half of the sample. Because the RMS level of this first half is 1 dB lower than the RMS level of the full-size sample, one must increase the difference RMS level figures by 1 dB for comparison with the synchronized mode.

Here for the gear
Great work Didier!
Here is my little contribution:

Lyra 2

Digi 003

I am not so sure with these results though. They seem much worse than the previous ones of the same interfaces, but maybe you can allign them better in audio diffmaker and get deeper null. Please PM me if you find these files to far off too post them.

It seems perfect. Here's the result for the Lyra 2:

ADM: 588,9usec, 0,000dB (L), -0,019dB (R)..Corr Depth: 31,0 dB (L), 32,6 dB (R) Difference: -51.3 dBFS (L), -52.6 dBFS (R)
Matlab: 588.76 µs, -0.0022 dB (L), -0.0207 dB (R) Difference: -51.3 dBFS (L), -52.6 dBFS (R)

I will process the Digi 003 file and adds the results to the list later on.
