Hi pkane, thanks for developing this, it's looks so incredibly useful and promising to shed light on perceived difference in digital audio reproduction..
I also posted on your website but I seem to perhaps have run into a bug?
I seem to have a problem with measuring the R channel exclusively, I always get completely off the chart delta phase results. I did all kinds of cross checking with different dacs, output modes, feeding the R out into the L of my ADC, swapping the channel in my test files and using different reference test files, but everything seems to point to a software bug. Also in stereo mode, I don't get the problem either. Could you please let me know if you can reproduce or if you need debug logging? It never happens on channel L.
Audio data on channel R

Same exact data on same ADC input from channel L (multiple DACs)

Thanks again
Probably not a bug. You need to select both, the reference and the comparison file channels to run the comparison. Both should be set to R if you want to compare right channels. If Comparison is set to R and Reference is set to L, you're comparing left channel to right, which will result in a large phase error.
Edit: Oh, and if you're using the built-in recorder in DeltaWave, you'll need to select 'stereo' for channels in the recorder, otherwise only one channel mono will be recorded.
