Add support for this from the command line. Everyone who adds sound hardware to a computer has the urge to come up with their own file format. I don't know DSP at all. A Pitch Shifter is high on the list. Someone needs to add this in.
Some file formats have space for embedded comments.
These are currently thrown away. Printing them out, carrying them forward, and an to add new ones would be handy. Not really fit for graphing since it is only a stream of ascii sample values but some program appear to like it. Also has a much nicer header. It wants to be class-based.
