Understanding Channel Configurations

The Wwise pipeline supports multiple channel configurations at different levels depending on the source material, the output device, the bus settings, and so on. Different platforms also have different limitations.

Here are the different channel configurations found in Wwise with the channel names, suggested angles for the speakers and ordering:
