Abstract

Un sistema para capturar sonido que comprende una pluralidad de micrófonos discretos (112, 114, 116, 118) y un sistema de procesamiento (408). La pluralidad de micrófonos discretos se dispone en una matriz circular. El sistema de procesamiento (408) dispuesto para llevar a cabo un primer algoritmo de procesamiento de señales en el sonido que se origina desde uno o más de un primer conjunto de direcciones con relación a la matriz para aislar una primera fuente de sonido. El sistema de procesamiento (408) se dispone además para llevar a cabo un segundo algoritmo de procesamiento de señales en el sonido que se origina desde uno o más de un segundo conjunto de direcciones con relación a la matriz para aislar una segunda fuente de sonido en el mismo. También se describe un método para recibir sonido en una pluralidad de micrófonos discretos (112, 114, 116, 118) dispuesta en una matriz circular.
