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:

1.0 (mono)
Interface Element	Description
Center (C)	0 degrees

2.0 (stereo)
Interface Element	Description
Left (L)	22-30 degrees
Right (R)	22-30 degrees

3.0
Interface Element	Description
Left (L)	22-30 degrees
Right (R)	22-30 degrees
Center (C)	0 degrees

4.0
Interface Element	Description
Left (L)	22-30 degrees
Right (R)	22-30 degrees
Surround Left (SL)	90-110 degrees
Surround Right (SR)	90-110 degrees

5.1
Interface Element	Description
Left (L)	22-30 degrees
Right (R)	22-30 degrees
Center (C)	0 degrees
Surround Left (SL)	90-110 degrees
Surround Right (SR)	90-110 degrees
Low Frequency Effects (LFE)	N/A

7.1
Interface Element	Description
Left (L)	22-30 degrees
Right (R)	22-30 degrees
Center (C)	0 degrees
Surround Left (SL)	90-110 degrees
Surround Right (SR)	90-110 degrees
Back Left (BL)	135-150 degrees
Back Right (BR)	135-150 degrees
Low Frequency Effects (LFE)	N/A

Wwise also supports extended standard channel configurations with "height" speakers. Below is a definition of all available channels, followed by a description of standard configurations available on busses.

Standard configurations extended with height channels
Interface Element	Description
Left (L)	22-30 degrees

Surround Right (SR)	90-110 degrees
Back Center (BC)	180 degrees
Back Left (BL)	135-150 degrees
Back Right (BR)	135-150 degrees
Top (T)	Straight above
Height Front Left (HFL)	Same as L, above horizon
Height Front Center (HFC)	Same as C, above horizon
Height Front Right (HFR)	Same as R, above horizon
Height Back Left (HBL)	Same as BL (or SL), above horizon
Height Back Center (HBC)	Same as BC, above horizon
Height Back Right (HBR)	Same as BR (or SR), above horizon
