Abstract

Un aparato de codificación de audio comprende un receptor de audio (201) que recibe artículos de audio que representan una escena de audio y un receptor de metadatos (203) recibe metadatos de presentación de entrada para los artículos de audio que describen las restricciones de presentación para la representación de los artículos de audio. Las restricciones de presentación restringen un parámetro de representación que puede adaptarse al representa los artículos de audio. Un codificador de audio (205) genera datos de audio codificados para la escena de audio al codificar la pluralidad de artículos de audio con la codificación que se adapta en respuesta a los metadatos de presentación de entrada. Un circuito de metadatos (207) genera metadatos de presentación de salida a partir de los metadatos de presentación de entrada. Las metadatos de presentación de salida comprenden datos para los artículos de audio codificados que restringen la extensión mediante la cual un parámetro adaptable de una representación puede adaptarse al representar los artículos de audio codificados. Una salida (209) genera una corriente de datos de audio codificada que comprende los datos de audio codificados y los metadatos de presentación de salida.
