Lance,
I'm the developer of libsndfile.
Since you are posting to the DEVELOPER's list I will assume that you
are a developer. It sould be trivial to modify the sfplay program
from libsndfile to do what you want.

It doesn't currently work in sfconvert, but libsndfile recognises
"-" as the appropriate filename stdin or stdout. Again, modifying
sfconvert to do this would be trivial.

VOC is coming in libsndfile version 1.0.0 due out RSN (real soon now).

Journalist: Microsoft CEO Steve Ballmer has finally said Linux
is the No. 1 threat to Windows. What's your response to that?
Linus : "Tag, you're it." I don't care. They've had a lot of
enemies in their time. Let them fight one enemy that
doesn't care for a change.
