beat detection in audio.. I'm trying to figure out how to detect 'beats' in audio. Audio peaks don't quite cut it.. I'm tempted to 'record' a beat track on the music i want to use, and trigger off that, but that would limit me to using music that i've pre-recorded..

I haven't made actual progress on this, but this is what I am background reading from, prior to trying to make this happen, using XCode Beat Detection, for a custom patch approach, although I guess with a little careful sorting of a split structure, averaging of index clumps 0 - 5, ..., etc, one could algorithmically reproduce the overall logic required for the process to succeed using a set of QC's own math, script and logic patches.
There are lots of threads at http://www.cycling74.com/forums/index.php about sound responsive stuff.
To paraphrase somebody – easy to make reactive (eg. peak volume) to create something meaningful can be a long term pursuit. Have to second that. I haven't made or seen much that is more than peak-reactive, which rarely cuts it IMHO.
tb's randomwalk cybero modified for sound almost got there!
I've never had time to try it, but this may be a lead:

It's a max/msp runtime that supposedly sends to QC via midi.
It's definitely a lead, but one that requires max/msp, though I can't help but wonder if it can't be re-jigged to run rather more generically.
It's actually a max msp runtime, so no max install needed.
thanks for the clarification
