Abstract

Un aparato para descomponer una señal de entrada que tiene un número de por lo menos tres canales de entrada comprende un mezclador descendente (12) para ejecutar la mezcla descendente de la señal de entrada para obtener una señal con mezcla descendente que tiene un menor número de canales. Asimismo, se presenta un analizador (16) para analizar la señal con mezcla descendente a fin de derivar un resultado del análisis, y el resultado del análisis 18 es reenviado a un procesador de señales (20) para procesar la señal de entrada o una señal derivada de la señal de entrada para obtener la señal descompuesta (26).
