geeky musings; or, I hung out with too many DJ's this weekend

I wonder if it's possible, through wave analysis (IE the fast-fourier transformation), to figure out the BPM of a song. Because then you could run it, and have your MP3s sorted by folders or playlists named 120BPM, 130BPM, etc. Then if you wanted to mix stuff it would be easy.

Oddly enough...

... I tried to do this exact thing at my last job (determining BPM of music through FFT/wave analysis). I needed it for the purposes of syncing up interactive electronic art pieces with music beats. Alas, I never quite got it working... had a lot of problems with filtering out extraneous aspects of the waveform. We later found a hardware solution of sorts, little black boxes that claim to be able to determine the BPM and are used by DJs for syncing up selections and MIDI driven devices. But it really wasn't all that more reliable than my software solution.

good to know

By the way, you're marvelous.

Wow.
