The Audio Auto Pan behavior automates commonly used panning effects in an audio track. Adjust this behavior using the controls in the Behaviors 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 to increase volume in one channel and decrease volume in the other channel over the behavior’s duration, giving the impression of a sound moving from one direction to another.
Volume: A pop-up menu that sets how audio levels are affected during the pan. Choose from five 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 barrier is met. If you choose Over Entire Duration, the Auto Pan affects audio level changes over the duration of the track.
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.
