Abstract

La invención se refiere a un aparato (1) para el procesamiento de una señal de audio codificada (100) que comprende una pluralidad de señales de mezcla descendente (101) asociadas a una pluralidad de objetos de audio de entrada (111) y parámetros de objeto (E). El aparato (1) comprende aun agrupador (2) configurado para agrupar las señales de mezcla descendente (101) en grupos de señales de mezcla descendente (102) asociados a una serie de objetos de audio de entrada (111). El aparato (1) comprende un procesador (3) configurado para ejecutar por lo menos un paso de procesamiento individualmente en los parámetros de objeto (Ek) de cada serie de objetos de audio de entrada (111) a fin de emitir resultados de grupos (103, 104). Se presenta además un combinador (4) configurado para combinar dichos resultados de grupos (103, 104) o resultados de grupos procesados a fin de emitir una señal de audio decodificada (110). El agrupador (2) está configurado para agrupar las señales de mezcla descendente (101) de tal manera que cada objeto de audio de entrada (111) pertenezca sólo a una serie de objetos de audio de entrada (111). La invención se refiere asimismo a un método correspondiente.
