Use the Audio controller to drive the animation of almost any parameter in the software. The Audio controller converts the amplitude of a recorded sound file or real-time sound wave into values that can animate an object or parameter.

With the Audio controller, you have full control over sound channel selection, base threshold, oversampling, and parameter range.

The Audio controller works with most parameters in Track View, including:

Transforms
Float values
Point3 values (color)
