A method of synthesizing a three dimensional sound-field using a pair of front and a pair of rear loudspeakers, including: a) determining the desired position of a sound source; b) providing a binaural pair of signals corresponding to the sound source using an HRTF filter; c) providing the left signal of said binaural pair of signals to both the left front and left rear loudspeakers through a front and a rear gain control means respectively; d) providing the right signal of said binaural pair of signals to both the right front and right rear loudspeakers through a front and a rear gain control means respectively; e) controlling the ratio of the front signal gains to the rear signal gains as a function of the azimuth angle of the sound source; and f) performing transaural crosstalk cancellation on the front and rear signal pairs through respective transaural crosstalk cancellation means. |
