audio file handling

Phil, my AudioWaveform component will read the WAV and AIF headers,  
and I don't think it would be a huge stretch to re-write the headers,  
but if you need to perform sample rate conversions (and it sounds  
like you do), it won't be much help.

I have no knowledge of what a decent sample-rate conversion algorithm  
might consist of, but I'm pretty sure that it would be non-trivial,  
and probably not the sort of thing that Transcript is well suited  
for. Maybe it can be done using Quicktime?
