The information on this page is specific to Doom 3 .

Description

The mask_backleft keywork only allows sound from the shader to be outbut through the rear left surround sound speaker in a 5.1 setup.

Usage

When this is in use, sound only comes from that channel when 5.1 surround is used. If you use 2 channel (stereo) sound the channel will be muted and this sound will not be played.
