Abstract

Un aparato (100) para determinar una señal de audio multicanal de salida espacial con base en una señal de audio de entrada y un parámetro de entrada. El aparato (100) comprende un descomponedor (110) para descomponer la señal de audio de entrada con base en el parámetro de entrada para obtener una primera señal descompuesta y una segunda señal descompuesta diferente una de la otra. Adicionalmente, el aparato (100) comprende un representador (110) para representar la primera señal descompuesta para obtener una primera señal representada que tiene una primera propiedad semántica y para representar la segunda señal descompuesta para obtener una segunda señal presentada que tiene una segunda propiedad semántica que es diferente de la primera propiedad semántica. El aparato (100) comprende un procesador (130) para procesar la primera señal representada y la segunda señal representada para obtener la señal de audio multicanal de salida espacial.
