software to set pictures to music

Hi Andy,

my first thoughts to solve that problem would be to generate some
transition signal for the pictures from the sound files, i.e. to
extract the "rhythm of the music". You have to ask yourself how to
define that. With electronic music it basically comes down to a
bpm-counter-problem, which shouldn't be too hard to solve, I would
assume a relatively basic time domain algorithm, possibly just a peak
search, being successful. With other music, you'd need to extract e.g.
the drummer's sound, which is somehow more difficult, incorporating
some kind of filter for example.

But haven't done that. Just some ideas.
Good luck, and give some feedback some time.

Thanks for the hints

I'd be surprised if there wasn't already some kind of library already
available to do this though (or even an off-the-shelf application to do
exactly what I want)
