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.

Um método de synthesizing um som-campo tridimensional usando um par da parte dianteira e um par de loudspeakers traseiros, incluindo: a) determinando a posição desejada de uma fonte sadia; b) fornecendo um par binaural dos sinais que correspondem à fonte sadia usando um filtro de HRTF; c) fornecendo o sinal esquerdo de par binaural dito dos sinais aos loudspeakers traseiros dianteiros e esquerdos esquerdos com um controle dianteiro e traseiro do ganho significa respectivamente; d) fornecendo o sinal direito de par binaural dito dos sinais aos loudspeakers traseiros dianteiros e direitos direitos com um controle dianteiro e traseiro do ganho significa respectivamente; e) controlando a relação dos ganhos dianteiros do sinal aos ganhos traseiros do sinal em função do ângulo do azimuth da fonte sadia; e f) executar o cancelamento transaural do crosstalk no sinal dianteiro e traseiro emparelha-se com os meios transaural respectivos do cancelamento do crosstalk.
