Music Ducking Extension
When music and voice signals are mixed together the desired behavior is often to lower the music signal's volume to make the voice more audible. This is a useful mechanism for listen together experiences where users also talk to each other.
Two signals are needed for this behavior:
- The ducked signal: usually the music signal, the volume of this signal gets lowered.
- The ducking signal: this signal controls the ducking algorithm. This is usually based on a voice signal that is noise filtered.
This extension provides the following audio nodes for a Switchboard SDK audio graph:
|MusicDuckingNode||Applies the ducking algorithm on the music signal. Receives the ducking signal and the music signals and outputs the ducked music signal.|
