Abstract
Un decodificador de audio para proporcionar al menos cuatro señales de canal de audio sobre la base de una representación codificada se configura para proporcionar una primera señal residual y una segunda señal residual sobre la base de una representación codificada conjuntamente de la primera señal residual y de la segunda señal residual usando una decodificación multicanal. El decodificador de audio se configura para proporcionar una primera señal del canal de audio y una segunda señal del canal de audio sobre la base de una primera señal de mezcla descendente y la primera señal residual usando una decodificación multicanal asistida por señales residuales. El decodificador de audio se configura para proporcionar una tercera señal de canal de audio y una cuarta señal de canal de audio sobre la base de una segunda señal de mezcla descendente y la segunda señal residual usando una decodificación multicanal asistida por señales residuales. Un codificador de audio se basa en las correspondientes consideraciones.
