ABSTRACT:
A multi-channel stereophonic sound recording system of the invention comprises a three-dimensional structure simulating the human head and a plurality of microphones mounted in the head-simulating structure and angularly spaced about its vertical or principal axis. An acoustic crosstalk cancellation circuit is connected to receive signals from the microphones to provide such signals as will produce a binaural effect when reproduced through loudspeakers without causing dislocation of the virtual sound sources even when the listener turns his face in the sound field.
