Perhaps
http://docs.python.org/lib/module-wave.html
will help. I used it to create an echo effect toy for my grandson by reading
existing .wav sound effect
files and adding delayed reduced-aplitude feeback to itself and writing another
file. Parameters were
distance in feet to a reflecting wall (assuming 1000 ft/sec sound speed ;-) and
relection volume factor.
Not hard. Maybe make yourself a little utility first that will show you the
specs for any .wav file (i.e.,
sampling frequency, bytes per sample, channels, etc.) I don't recall at the
moment whether you have to
deal with signed or offset amplitude values, but it won't be hard.
This won't play the sounds though.
