This video shows how to use the left and right peak readings from sound playback, as well as use its audio waveform spectrum analysis to create some simple image effects that match the sound.

Again, framerate is low due to the video capture process; the original one runs much better. Also, I couldn't get the sound properly recorded with the video, so I had to manually add the sound to the video later, using After Effects; volume changes and such may not be totally synchronized.

ALSO, it was pretty late when I recorded this, so please don't mind the mistakes I do while creating the patch, like linking stuff to the wrong connector.
