Audio Behaviors
Audio behaviors can be applied either to audio tracks from movie clips with sound or
standalone audio tracks. There are several ways to apply an audio behavior:
 Dragging an Audio behavior from the Library directly to an audio track in the Audio
tab or Timeline
 Selecting a track in the Audio tab or Timeline and then clicking the Add Behavior
icon in the Toolbar and choosing an Audio behavior from the pop-up menu
For more information about applying behaviors, see “
There are two useful behaviors to control audio tracks in Motion:
Audio Auto Pan
Automates commonly-used panning effects in an audio track.
Parameters in the Inspector
Pan Position: Sets the position of the pan. If the Pan Position is set to 0, the sound is
equally balanced between the left and right channels. With larger negative values of
Pan Position, the sound increases in volume in the left channel and decreases in the
right channel. With larger positive values of Pan Position, the sound increases in volume
in the right channel and decreases in the left channel.
Depth: Sets how far the automatic pan occurs in the left and right channels. Values
range from 0 to 100.
Direction: Sets the direction in which the pan moves over the behavior’s duration.
Value can be set to Left or Right. If the direction is set to right, over the behavior’s
duration the volume of the audio decreases in the left channel as it increases in the
right channel, giving the impression of a sound moving from left to right. If the
direction is set to Left, over the behavior’s duration the volume of the audio decreases
in the right channel as it increases in the left channel, giving the impression of a sound
moving from right to left.
Volume: Sets how the audio levels are affected during the pan. Value can be set to
Constant, Ramp Up, Ramp Down, Crescendo, or Decrescendo.
Peak type
Description
Ramp Up
An animation curve that creates a constant increase in volume
Ramp Down
