Thanks
I just realized I saved the file as 16bit rather than 24. Would that make any difference? (pardon the pun)

No difference expected because 16 bit quantization error (< -90 dBFS) is much smaller than the -40 dBFS conversion error measured here.

List of results updated with test of Eventide H8000FW and MOTU 828mk3 by jeamsler.

DA-AD 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.

I notice that in the list the corr depth from diffmaker tracks closely with the difference values you get with matlab. But I noticed that for the Eventide H8000 the corr depth did not seem to match the difference values compared to the list as a whole. The pattern of values would suggest a corr depth of 46db would get a difference value of -50plus not -39 suggesting diffmaker found a greater null than you did somehow. How come the anomaly in the data?

I noticed that also and do not have any explanation. However the delay and gain values delivered by ADM are too close from the ones delivered by Matlab for allowing a significant discrepancy between the difference level values, which is confirmed by the measurement of the RMS level of the difference wav file delivered by ADM. Corr. depth stands for correlated null depth. Null depth is known. I do not know what it is exactly correlated null depth. Google can't help.

The simple answer is look at the last measurement. The "difference" is better the lower. So -59 dB is better than -48 dB.
This test have been run with interfaces A/D and D/A. Also external clocks, seperate Dacs and Adcs.
Two trends I notice. Interfaces with a single Codec (one chip is ADC and DAC) measure better. The AK4620 based interfaces outperform the ones with the same vintage separate converters. Also the inputs that goes through a microphone preamp tend to measure worse. Several interfaces run all analog through mic pres.

We've already got quite a few of these tested, so don't bother with it if it's too much of a hassle.

Sorry, I used the same (****ty) filehost again, because I don't want to register with mediafire.

Better measured ADC or DAC interfaces

Hello Didier and All,

Given these measurements, is there any way to rank interfaces from best measured to worst measured by either their ADC or their DAC capability? What if I care only for ADC or only DAC quality in an interface? Can that be ascertained from these tests? Has that kind of test been done "objectively" that you know of?

I can see some variation in the tests done with different ADC and DAC interfaces in this thread, and that certainly helps some. But it doesn't seem to be a complete objective test of one side of the conversion or the other, just a derivation/observation of likely quality.

I am very familiar with the importance of listening and use testing for any particular studio, and the fact that only "your ears can tell what you like and what works for you" (that is everywhere on these forums). So I don't want to go there in this thread at all.

Can strictly ADC quality or DAC quality be derived from these tests, or do I need to look elsewhere for measurement tests that do this? If elsewhere, any links?

Thanks. Ben

You're right, the test is not objective.
Different levels, different loopbacks, different PC's with different RFI noise issues, different cables, different impedances, different sample alignments.
The test results aren't meaningful in ANY way in relation to eachother. No emperical conclusions can be drawn from this "test"

And in spite of different PC/RFI/Cables the same units are returning very consistent results when tested by different people under those different variables. While it would be nice to see a lot more of that, at this point it's fair to say those variables (PC/RFI/Cables/etc) have been fairly well controlled for.

This test has the possibility of a false negative, but not a false positive.

One thing that can be objectively () observed here is that the $$,$$$=good crowd are showing a %100 rejection rate of these results.

I don't personally put a ton of weight in the importance of this because I see a slight phase shift as being relatively insignificant...but I do see this as more proof positive that people put way too much emphasis on converters. I have purple 192s, Focusrite Red 8Pres, and Motu track16 and a behringer UMC and they are all fine for pro work assuming the unit has the functionality needed for the job.

List of results updated with tests of Digidesign Digi 002 Rack with Black Lion Audio Signature mod. and Universal Audio Apollo Twin Mk II

DA-AD 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.
