Abstract

Una unidad de cálculo para un sistema de reproducción de sonido que comprende medios de entrada, un procesador y al menos tres salidas para controlar al menos tres transductores de un arreglo. Los medios de entrada tienen el propósito de recibir un flujo de audio que será reproducido usando el arreglo, donde el flujo de audio tiene un intervalo de frecuencia. El procesador es configurado para calcular tres señales de audio individuales que serán producidas usando al menos tres salidas, de modo que sea generada una primera diferencial acústica que tenga un segundo orden o superior usando el arreglo.
