Objet : [scilab-Users] Working with audio
I'm new to Scilab, and I'm having a difficult time figuring out how I can
analyze the signals in these mp3s:

How would I go about this? Is there any way I import the file without
requiring it to be a .wav file? I have converted, but I'd like to not lose
in a audio quality through transcoding it from an already lossy format.
I did convert it to .wav to see if I could use wavread and analyze, as
mentioned at http://cermics.enpc.fr/~jpc/mopsi/doc/ch19.html
Wavread told me "mget: stack size exceeded (Use stacksize function to
increase it)." So, I tried
y=wavread("test.wav", [1 5])
That made it not complain, but I'm not sure what that does.
analyze(y) and mapsound(y) complain that y is an undefined variable after
what I thought was already assigned above.
I need a decent overview of how to work with audio in Scilab and hope
someone here can help.
