The Wwise Project Adventure

Another approach to ducking is through the use of Side-Chaining. Side-chaining consists of monitoring the level of an audio signal and using it to manipulate another audio signal. A concrete example of side-chaining occurs in radio broadcasting where a DJ's voice automatically ducks the music volume.

When using Side-Chaining as part of mixing, you are essentially taking volume information from input signal with the Wwise Meter effect and using it to affect other parts of the mix.
