[PD] Phase Cancellation

[Chuckk Hubbard]

If it's exactly the same, you should be able to just use [-~] on the
unaltered signals.  Phase cancellation would only work for a handful
of frequencies at a time.
If it's not exactly the same sound, it'll be pretty complicated.
Sometimes if you check out how it was mixed, you find one part is
lower on one side or the other.  If the violin's mostly on the left,
try just the right track, unless your drum loop is stereo.
