Abstract
A system for controlling distribution of sound in a multi-channel sound system such as a 'surround sound' system in a movie theater. Control signals are used to steer, or distribute, portions of the sound signal between designated speakers. In a preferred embodiment the control signals are provided with the sound signals, themselves, and are separated from the sound signals by using a pilot signal or signals.
