Abstract

Un codificador de escena de audio para codificar una escena de audio, donde la escena de audio comprende al menos dos señales de componentes, que comprende: un codificador central (160) para codificar centralmente las al menos dos señales de componentes, en donde el codificador central (160) está configurado para generar una primera representación codificada (310) para una primera parte de las al menos dos señales de componentes, y para generar una segunda representación codificada (320) para una segunda parte de las al menos dos señales de componentes, un analizador espacial (200) para analizar la escena de audio para derivar uno o más parámetros espaciales (330) o uno o más conjuntos de parámetros espaciales para la segunda parte; y una interfaz de salida (300) para formar la señal de escena de audio codificada (340), donde la señal de escena de audio codificada (340) comprende la primera representación codificada (310), la segunda representación codificada (320) y el uno o más parámetros espaciales (330) o uno o más conjuntos de parámetros espaciales para la segunda parte.
