This script turnes a pair of wav files into a pair of text files with one
sample per line and diffs them, it is pretty simple and did the job, but
its not very efficient. I used it to check dodgy spdif cables :)

run it with eg. "./audio-diff file1.wav file2.au"
it doesnt like float wav files though, cos it uses sox.

audio-diff:
-- cut --
#!
sox $1 /tmp/$$-a.dat
sox $2 /tmp/$$-b.dat
diff /tmp/$$-a.dat /tmp/$$-b.dat
rm -f /tmp/$$-a.dat /tmp/$$-b.dat
-- cut --
