READ

http://docs.python.org/library/wave.html

Also see

help(sage.media.wave)

in Sage. I guess the wave file has to be uncompressed. I have no
idea how to uncompress a wave file.

You could also try:

import scipy.io.wavfile
help(scipy.io.wavfile)

I tried a few compressed wav files and it failed on them.

You can also try googling for "python wav", which will result in many
hits, e.g.,

http://stackoverflow.com/questions/2060628/how-to-read-wav-file-in-python

Obviously it *should* be the case that one can just do:

sage: a= load('most_an_file.wav')

and get back something nice and useful, or get a useful error message.
But nobody has implemented anything like that yet in Sage! I wish
they had.
