I implemented and tested that feature some two years ago, but never got
around to releasing it.  I think that it will decode the pulse stream
directly.  Actually, you may get better results by feeding the WAV file
through TAPir and passing the .tap file (pulse stream) to c2n.  But
there may have been a reason why TAPir would not work on tapes containing
phase changes (half-waves), as in the Commodore 16 .tap format and in the
native format of the Tangerine Oric-1 or the KIM-1.

Looking at the source code, c2n processes full-waves internally.
Then the only reason not to use an external program like TAPir would be
if one did not have enough storage for the .tap or .wav file and chose
to sample the tape in real-time.
