good advice.

in my experience, not so good advice. lexer+parser generators are great
for certain kinds of things, actually more like indispensable. but for
parsing audio files, they really are not very well suited for the task.
these are binary files with no real semantic structure other than
"chunks". i have no doubt that you could use them, but erik de castro
lopo didn't for libsndfile and thats good enough for me :)
