there must be some established numerical recipes for beat detection
... an i7 cpu can handle a lot and maybe use some JS matrix
computation library that runs stuff on the GPU (via WebGL) ... I did
come across one a while back
with beat detection, for example, you can animate the rotating square
thing that you've made (half circle clockwise and then rotate back, or
something like that) in sync with the beat! :) boom boom
meanwhile, working on animating a bar chart (with negative and
positive values, and switching between data sets and scale types..)
HOW MUNDANE IN COMPARISON!!
Lucky u :) Can't wait to catch up
