Modules
In Wwise, a bus is where multiple audio signals are mixed together to form a single audio signal. Busses only exist in the Master-Mixer Hierarchy. All Wwise projects have at least one audio bus called the Master Audio Bus, and all sounds that will be heard in the game eventually flow through this bus.
-
Launch Wwise and open a project file. Make sure you open the Module 12 project file.
-
In the Project Explorer, select the Items Actor-Mixer. Then in the Property Editor, select Routing.
Notice the Output Bus is set to Master Audio Bus. Because this is set on the Actor-Mixer object, all child objects are assigned to the Master Audio Bus as well.
-
Expand Master-Mixer Hierarchy > Default Work Unit, and then select Master Audio Bus.
In the primary editor, you see an audio meter. Meters are not available on Actor-Mixers because no audio actually passes through an Actor-Mixer.
-
Expand the Items Actor-Mixer, and then select the Teleporter object. Reselect the Master Audio Bus and press Spacebar to play the Teleporter object.
The Master Audio Bus meter displays the overall sound level feeding the bus.

If you have Wwise set up for surround sound playback, you might see a different meter layout.
