motion math

[Colin Braley]

Nope motion math no longer exists but you can use the “convert audio to keyframes” assistant the comes with AE. It will create a null layer which has the sliders the represent the audio ampliture of the left channel only, the right channel only, and of both channels. If you need a more detailed solution check out trapcode’s “sound keys” plug-in which allows you to acess the volume of different ranges of sound.
