Interesting that at a setting of 0 on the Xonar and WSJT-X showing 30 on
the audio scale the levels in the WAV file were really low.
You'd think that WSJT-X showing 30 would show a consistent level since I
assume the WAV file is the same data used as the audio gain is using, isn't
it? So modifying record levels as long as you adjust to 30 on the audio
should produce essentially the same amplitudes int the WAV file I would
think.
Changed to the dB scale and that ends up being the 51% point for the
Xonar. The old setting with the really low audio in the WAV file was
-58.4dB
