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.An audio scene encoder for encoding an audio scene, wherein the audio scene comprises at least two component signals, comprising: a central encoder (160) for centrally encoding the at least two component signals, wherein the encoder Central (160) is configured to generate a first coded representation (310) for a first part of the at least two component signals, and to generate a second coded representation (320) for a second part of the at least two component signals , a spatial analyzer (200) for analyzing the audio scene to derive one or more spatial parameters (330) or one or more sets of spatial parameters for the second part; and an output interface (300) for forming the encoded audio scene signal (340), where the encoded audio scene signal (340) comprises the first encoded representation (310), the second encoded representation (320), and the one or more spatial parameters (330) or one or more sets of spatial parameters for the second part.
