Abstract
An optimal listening position for the multi-channel audio sound system is determined. A listening area and other audio playback controls may also be defined or modified by a listener. During subsequent audio playback, an imager captures images of at least a portion of the listener. When the listener has moved to a position that is different from a previous position, one or more audio parameters are adjusted for at least one channel in the multi-channel audio system in order to reposition the initial or previous optimal listening position to the current position of the listener. When the listener moves outside the listening area, an out of bounds response is initiated to disable or control the audio playback until the listener moves to a position within the listening area.
