Abstract

Una unidad de cálculo para un sistema de sonido comprende un medio de entrada, un procesador y un medio de salida. El medio de entrada tiene el propósito de recibir una corriente de audio que se va a reproducir utilizando el sistema de sonido. El medio de salida tiene el propósito de controlar el sistema de sonido con base en una primera y una segunda pluralidades de señales de audio individuales. El procesador se configura para calcular la primera pluralidad de señales de audio tal que se realice la modelación de haz por el arreglo y para calcular la segunda pluralidad de señales de audio individuales para realizar, utilizando el sistema de sonido, la supresión directa de sonido tal que se cancele el sonido hacia una dirección de escucha. Adicionalmente, el procesador filtra al menos la segunda pluralidad utilizando una segunda característica de banda de paso que comprende una segunda porción de todo el intervalo de frecuencia.
