Let's say you have an Audio Device with 16 channels on your master Audio Bus and want to output 7.1 content on the first 8 channels (1 to 8) followed by 4.0 content on the next 4 channels (9 to 12) with silence on the remaining channels (13 to 16).
-
Add the Wwise Channel Router plug-in to your master Audio Bus. See Mixer Plug-in for how to set up a Mixer plug-in.
-
Create a new child Audio Bus under the master Audio Bus and set its channel configuration to 7.1. Let's name it "Audio Bus 7-1".
This bus inherits the properties of the Wwise Channel Router from its parent bus.
Leave the Channel property of the Wwise Channel Router plug-in set to 1 to output starting from the first channel.
-
Create another child Audio Bus under the master Audio Bus and set its channel configuration to 4.0. Let's name this one "Audio Bus 4-0".
For this child bus to output starting from channel 9 (into channels 9 to 13), set the Wwise Channel Router Channel property to 9.
Here is a summary of the example bus configuration:
-
Master Audio Bus (Channel Configuration: Anonymous 16 / With a Wwise Channel Router Mixer Plug-in attached)
-
Audio Bus 7-1 (Channel Configuration: 7.1 / Wwise Channel Router is automatically inherited, Set the Channel property to 1)
-
Audio Bus 4-0 (Channel Configuration: 4.0 / Wwise Channel Router is automatically inherited, Set the Channel property to 9)
-
The following figure illustrates how the channels will be routed according to the Channel property and the number of channels for each bus.
