Abstract (en)
An improved method and means of reproducing sound includes processing the pair of signals (2, 4) representing left and right stereophonic channels to produce a signal which is the linear algebraic difference of the pair of left and right signals (2, 4) and includes acoustically radiating the left and right stereophonic signals (2, 4) toward a reception region (13) in substantially the same one direction from a pair of spaced locations (10, 11), and also acoustically radiating the difference signal toward the reception region (13) in substantially the opposite direction from a location (12) which is spaced in the one direction away from the pair of spaced locations (10, 11).
