I should add: I prefer not to expand the entire file to WAV and crunch
on that. This is partly because I want to look for silences in
specific places in the mp3 without having to decode the whole file,
partly because I still need to know where the original mp3 frames are
in the file. For the actual files I want to crunch, I don't need to
handle VBR, but it would be nice to support it just from the point of
view of doing things right.
