I am making a utility to edit loop points in audio files.  I can use sox
for all my other audio file manipulation.  I was going to wait until my
utility was complete before responding to this thread.  I was also going
to do some more testing of loscil.  I am using csound4.

Thank you everyone for the useful responses.

Cheers,

Ben
