Now come on, WHY would I do that?



...the sound is after all coming *from* my PC. ;-) The logical thing to 
do with be to decode the Vorbis files back into WAV files and analyse 
the resulting spectrum. Although this is far, far less trivial than 
you'd imagine. (E.g., WinAmp can't reliably decide what the beat rate is 
either, mainly because it can't "hear" the beats reliably.)

I was going to sit and write some elaborate Haskell thing using a GTK 
front-end. But seeing how easy it is to do this with JavaScript and 
HTML, it's quite obvious that this is the best way to proceed.
