Abstract
Se proporciona un aparato para decodificar una señal multicanal codificada de una trama actual para obtener tres o más canales de salida de audio actuales. Un procesador multicanal se adapta para seleccionar dos canales decodificados de tres o más canales decodificados según los primeros parámetros multicanal. Más aún, el procesador multicanal se adapta para generar un primer grupo de dos o más canales procesados a base de dichos canales seleccionados. Un módulo de llenado de ruidos se adapta para identificar al menos uno de los canales seleccionados, una o varias bandas de frecuencia, dentro de las que todas las líneas espectrales se cuantifican a cero y para generar un canal de mezcla usando, según la información secundaria, un subgrupo apropiado de tres o más canales de salida de audio previos que fueron decodificados y para llenar las líneas espectrales de bandas de frecuencia, dentro de las que todas las líneas espectrales se cuantifican a cero, con ruido generado usando líneas espectrales del canal de mezcla.
