Are there any Linux audio applications that would allow me to invert
a WAV
file and sum it (mix it) with another file and then display the
resulting
waveform? If they're identical I'd get a flat line (the two would
sum to
silence); if not I'd hear see and hear noise. With a graphic display
I'd
also be able to see if there are any patterns to the errors.
For one: Sweep with "swh-plugins".
Select all, copy, "Process-->Inverter", "Edit-->Paste Mix".
