Thanks for the link; I'll check it out as soon as I get back to my
Mac's webbrowser.
Now, since I'm a little hard of hearing, I need to examine sound
samples in such a way that I can get a numeric value back. A real
world number, in a very practical sense, I mean. Hence my interest in
Unix. I guess it's what you'd call spectral analysis, and digital
signal processing. For instance, if there are going to be a bunch of
frequencies outside of my hearing range, and I won't actually be able
to hear them, I'd like to know which frequencies they are, in terms of
actual numbers, and then use a low-pass filter to cut them off.
