Import
iPhoneSong-Drums.wav
and place it in the timeline. Be sure to

Right-click on the new audio layer and select
Keyframe Assistant
and then
select
Convert Audio to Keyframes

effects in it. The new layer is named
Audio Amplitude
. The effect we'll be
using to drive our expression is the
Both Channels
expression. This effect
essentially just has a value that corresponds to the amplitude of the audio
file we generated from keyframed on every frame of video. Cool eh?
