Drag the audio clip (or video clip with audio) from the Media list (in the Project pane)
to the Source Audio well in the Behaviors Inspector.
To apply the Audio parameter behavior via the shortcut menu
1 In the Audio list, select the track.
2 In the Audio Track Inspector, control-click an audio parameter (such as Level), then choose
Audio from the Add Parameter Behavior submenu of the shortcut menu.
The Audio parameter behavior is added to the project. However, no Source Audio is yet
applied.
3 Do one of the following:
In the Behaviors Inspector, click the To pop-up menu (in the Source Audio row) and
choose a source audio track.
Drag the audio clip (or video clip with audio) from the Media list (in the Project pane)

Audio
The Audio parameter behavior performs an analysis of a specific property of an audio
track, then applies an animation curve to a parameter based on that analysis.
Parameters in the Inspector
Source Audio: Sets the audio track from which to read audio data. Can be set to any
single audio track in the project, or the Master track. Drag an audio clip or a video clip
with audio into the Source Audio well, or use the pop-up menu to choose a source for
audio analysis.
Note: For the Audio parameter behavior to have an effect on an object, audio must be
present in the Audio Timeline at the position of the behavior.
Respond To: A pop-up menu that sets the type of audio data analysis to perform. Choose
Amplitude or Transients. If set to Amplitude, the behavior responds to peak values of a
particular frequency. If set to Transients, the behavior responds to rapid changes in
frequency.
Graph Range: A pop-up menu that sets the initial range of frequency values to be analyzed
by the behavior. There are four options: All Frequencies, Bass, Mid, or Treble. The choice
of display affects the frequency range of the Low Frequency and High Frequency
parameters below.
