Houdini CHOP Talk 3 Audio Processing 1 - Audio Spectrum

Here I show how to use CHOPs in Houdini to deform geometry with audio.
I quickly walk though the set up to use what we make as velocity fields in a FLIP sim. The flip sim isn't the main point of this video, but it was interesting enough to include and if you're interested in diving deeper into it, the file is available on Gumroad.

The audio used from Six Umbrellas, it's a song named Downfall. It is used under Creative Commons, and can be downloaded here
