<p>A method and system for separating and ''unmixing'' prerecorded and mixed right and left stereo sound input signals into three or more output sound signals for sound reproduction by three or more loudspeakers (158-163, 168-173) spaced apart and located forward of a listener or listeners (153-157, 165-167). The output sound signals are linear combinations of the right and left sound input signals and uniquely satisfy conditions of sound linearity, symmetry, uniformity, normality, integrity, balance, constancy, and fidelity to create a substantially more accurate sound image of the recorded performance than that created by reproducing only the stereophonic sound input signals.</p> |
