Audio Auto Pan
Automates commonly used panning effects in an audio track.
Parameters in the Inspector
Pan Position:
A slider that sets the position of the pan. If the Pan Position slider 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:
A slider that sets how far the automatic pan occurs in the left and right channels.
Values range from 0 to 100.
Direction:
A pop-up menu that sets the direction in which the pan moves over the
behavior’s duration. Choose 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.

Working with Audio
Volume:
A pop-up menu that sets how audio levels are affected during the pan. Choose
from four options:
• Constant: An animation curve that allows no change in volume.
• Ramp Up: An animation curve that creates a constant increase in volume
• Ramp Down: An animation curve that creates a constant decrease in volume
• Crescendo: A logarithmic animation curve that creates a slowly accelerating increase
in volume
• Decrescendo: A logarithmic animation curve that creates a slowly decelerating decrease
in volume
Gain:
A slider that sets the target gain used for volume. Values range from –96 dB to
+6 dB.
Loops:
A slider that sets the number of times the auto pan effect repeats. Values range
from 1 to 30.
Apply Volume:
A pop-up menu that sets how audio levels change when the Auto Pan
effect repeats. Choose Once Per Loop or Over Entire Duration. If you choose Once Per
Loop, the Auto Pan affects audio level changes each time a loop marker is met. If you
choose Over Entire Duration, the Auto Pan affects audio level changes.
End Condition:
A pop-up menu that sets how the pan loops when the Auto Pan effect
repeats. Choose Repeat or Ping Pong. This setting has an effect only if Loops is set to a
value greater than 1.
Start Offset:
A slider that sets the number of frames from the beginning of the audio
after which the audio effect starts.
End Offset:
A slider that sets the number of frames from the end of the audio before
which the audio effect stops.

The HUD contains the same controls as the Inspector, except for the Start Offset and End
Offset controls.
