Hydroplanin Multitrack Audio Visualization

The goal of this visualization is to visually separate the voices of the beat. The beat was provided to me as nine separate .wav files, one for each voice. Each voice's volume level is tied to one of the images you see. The visualization is generated in realtime. The video and audio are a little off (< 1 second) in this capture, which is a horrible thing for an audio visualization, so please bare with me.
