do u have time to possibly convert this to capx ?
I'm afraid it isn't possible, even if I'd love to.
1) There seems to be no way to associate external sound files to C2 (web audio wouldn't mind, but there's no implementation)
2) The analyzer gives you access to peak and rms, but there's (currently) no way to distinguish between left and right channel (or any other number of channels in the audio stream)
If you read my tutorial about peak and rms, you will find there the .cap of dancer w/o the puppet part. Maybe it helps you
