Abstract

Un aparato para generar al menos una señal de salida de audio que representa una superposición de al menos dos objetos de audio diferentes, comprende un procesador para procesar una señal de entrada de audio a efectos de proveer una representación de objetos de la señal de entrada de audio, pudiendo esta representación de objetos generarse mediante una aproximación paramétricamente guiada de objetos originales por medio de una señal de mezclado descendente de objetos. Un manipulador de objetos manipula individualmente objetos utilizando metadatos basados en objetos de audio que se refieren a los objetos de audio individuales de manera de obtener objetos de audio manipulados. Los objetos de audio manipulados se mezclan mediante un mezclador de objetos de manera de obtener finalmente una señal de salida de audio que tiene una o varias señales de canal en función de un establecimiento de renderización especifico.
