ABSTRACT:
A multi-channel stereophonic system in which different audio signals are produced and caused to converge upon the ear of the listener at selectively spaced time intervals so as to enhance the realism of the sound impressed upon the listener. A pair of auxiliary speakers are arranged in front of and above a pair of conventional main speakers, and signals are transmitted from an audio source in selected phase relationship to each of the speakers, the sound produced at least by each of the auxiliary speakers being selectively reflected off of sound-reflective surfaces in order to physically separate the added sound produced by the auxiliary speakers from the conventional stereo speakers.
