Abstract

Un decodificador de señales de audio para producir una representación de señal de mezcla ascendente dependiendo de una representación de señal de mezcla descendente e información paramétrica relacionada con los objetos comprende un separador de objetos configurado para descomponer la representación de señal de mezcla descendente, a fin de proporcionar una primera información de audio que describe una primera serie de uno o más objetos de audio de un primer tipo de objetos de audio y una segunda información de audio que describe una segunda serie de uno o más objetos de audio de un segundo tipo de objetos de audio, que depende de la representación de la señal de mezcla descendente y usar por lo menos parte de la información paramétrica relacionada con los objetos. El decodificador de señales de audio comprende asimismo un procesador de señales de audio configurado para recibir la segunda información de audio y para procesar la segunda información de audio dependiendo de la información paramétrica relacionada con los objetos, para obtener una versión procesada de la segunda información de audio. El decodificador de señales de audio comprende asimismo un combinador de señales de audio configurado para combinar la primera información de audio con la versión procesada de la segunda información de audio, para obtener la representación de señal de mezcla ascendente.
