Abstract
Un aparato para descomponer una señal de entrada (10) que tiene un número de por lo menos tres canales de entrada, que comprende: un mezclador descendente (12) para efectuar la mezcla descendente de la señal de entrada a fin de obtener una señal con mezcla descendente, donde el mezclador descendente (12) está configurado para efectuar la mezcla descendente de manera que un número de canales con mezcla descendente de la señal de mezcla descendente (14) sea por lo menos 2 y menor que el número de canales de entrada; un analizador (16) para analizar la señal de mezcla descendente para derivar un resultado del análisis (18) y un procesador de señales (20) para procesar la señal de entrada (10) o una señal (24) derivada de la señal de entrada, utilizando el resultado del análisis (18), donde el procesador de señales (20) está configurado para aplicar el resultado del análisis a los canales de entrada de la señal de entrada o los canales de la señal derivada de la señal de entrada para obtener una señal descompuesta (26), donde la señal derivada de la señal de entrada es diferente de la señal de mezcla descendente.
