3-channel stereo sound
The accelerating sales of Dolby Surround Sound equipment shows that spatial sound is very much appreciated by music audiences. During the development of a surround decoder, it was thought sensible to use a third sound channel. the centre channel, with standard stereo recording. To prevent the sound of this channel drowning out the other two, its mono signal is formed from part of the sound of the two stereo channels.
