in thread How to compare 2 wav files.
Okay, if you and your friend agree on which 5-sec
portion to compare (e.g. always use the first 5 sec, not
counting any initial silence that might be present), then
you have a fairly good chance of building a DFT-based
discriminator/identifier with a pretty good success rate.
In this case, Perl could be very handy for driving the DFT/VQ engine on your friend's audio file, doing data reduction on that output, and running or maybe even computing the suitable statistics to identify a "best match" in your local database of first-5-sec snippets.
Just building your local database of "song signatures" will be a very instructive exercise, and you can use it for both "training" and "testing". I could go on... but it would all be speculative, and you should work it out for yourself.
