You can resample the 12kHz WSJT-X .WAV files down to 8kHz (there are

Audacity has long been my tool of choice for that. Not really sure I'd
say "degrade",
since 8ks/s is perfectly adequate for the usual <= 3KHz FT8 audio;
downsample
is true, but that's not degradation.

Hi Dana,
the degrade step I was referring to was the application of the
propagation model by the application. Agreed the resampling artefacts
should be small in comparison, but not insignificant due to the
non-integral rate conversion factors (8:12 and 12:8), if the best
resampling algorithm parameters are selected in the resampling tool.
