"In the way that xpointer can point to a portion of an XML file, is there
a parallel standard to point to a portion of a WAV of mp3 file?"
Do you mean for someone to actually call "file.mp3" and automatically
have your audio player advance to point X within that file? Or are you
simply approaching this from a "how do I describe this track at point X
If the former, I don't know of a technology that will allow you to jump
to the middle of a track based on a parameter passed in the URL.
*Maybe* SMIL or one of the more recent MPEG (non-MPEG 2, 3, or 4)
standards. If you're wanting to do the latter, as Daniel suggests:
METS and SMIL would work nicely. NYU Libraries have a nice example of
METS working in conjunction with SMIL.
