ABSTRACT:
Direct field sound, represented by the sum of left and right stereo input signals, is projected in a narrow dispersion pattern from a front radiating speaker 28,32 and reverberant field sounds, represented by difference between left and right stereo input signals, is projected from speakers 26,30 having a wide dispersion pattern. Direct field and reverberant field sounds are acoustically combined in space to create an improved representation of stereo sound.
