A CPAN search coughed up Audio::Wav right away, but it failed its test suite for me. Encoding and decoding wav files is a splendid way to learn pack/unpack, however. You will have difficulty if you hit exotic or proprietary compression formats. After Compline, Zaxo	[reply]

You should use sox. There is no CPAN sox module as far as I can tell, but it wouldn't be too hard to write one. Sox is a command line tool for manipulating audio files. It has a trim function that can be used to split audio files. Sox is fast. The fastest perl module for audio that I know of is Audio::Data, but it works on .au files not .wav. You can convert between these formats with sox. But once you have sox you won't need Audio::Data anyway. It should work perfectly the first time! - toma	[reply]

This is a non-perl solution but you could use Audacity, which is a free open source sound file editor. It seems pretty nifty to me.	[reply]

A few apps to do this have been popping up on freshmeat.net. This one seems nice WavBreaker And there is a commandline wavsplit I'm not really a human, but I play one on earth. flash japh	[reply]
