Happy new year to all !

List of results updated with MOTU 4pre test by ggsm27, Orion32+ | Gen3 test by Dan O, Tascam US-122L test by KindYak.

DA-AD loopback tests from this wav file (the original): http://www.mediafire.com/file/5hg6wl...inal2.wav/file,

The result from each test consists in four figures. Both first figures are the gains to be applied to the left and right channels of the loopback copy (download links available for a large part of the tests) for listening in comparison with the original. Both last figures are the RMS level values of the left (L) and right (R) channels of the difference between the original and the time and level aligned copy generated in Matlab by applying to the lopback copy a time delay, the same for both channels, and the L and R gains, the values of which given here are rounded to the nearest 0.1 dB. Precise values of these three parameters, determined to get the lowest maximum of L and R difference levels, were provided for each test before it was inserted in this list, except for the old ones that were initially measured by means of Audio DiffMaker and the result values of which have been meanwhile replaced without notification in this thread.

See at the end of this post how to contribute to the test.

For contributing to this test :
- download the test 2 x 44 kHz x 24 bit wav file (31 MB),
- cable link the 2 DAC outputs to 2 ADC inputs (separate DAC and ADC have to be driven by the same clock),
- play back the test file to the DAC outputs and record from the ADC inputs,
- upload to mediafire or any other file sharing site the 2 x 44 kHz x 24 bit wav file from this recording and
- provide the download link here with information about ADC and DAC identities (and the clocking for external clocking or separate converters).
Your contribution is welcome even if your converter is already in the above list.
Thank you !
