It'd be very acceptable if it did, I would actually have a use for it, then =)

Hmm.. Well, the audio you're getting from the card should be 48000 MP2.  Not 
sure why it dies but when you resample it to 48kHz, but the pitch shifting is 
probably because it's just taking the data as 32kHz instead of the 48kHz that 
it is..  Needs to do some resampling in the transcoder loop to handle that.
