In case you missed it, Harry Frank recently showed how to make Trapcode Particular‘s particles dance using Trapcode Soundkeys. Check out the tutorial at Harry’s site or over at Red Giant TV.

If you just gotta have more you can download Video Copilot’s free “Particle Animation to Music” project file. You’ll need After Effects CS4 and Trapcode Particular 2. The music is not included but you’ll be able to get a closer look at Andrew Kramer’s keyframes and amazing Particular settings.

In this episode, Aharon continues to explore how audio can be used to control time, but he expands on that by showing you how it can be used to change the look of the footage as well.
