Abstract

Se proporciona un aparato para generar una señal de salida de audio que tiene dos o más canales de salida de audio a partir de una señal de entrada de audio que tiene dos o más canales de entrada de audio. El aparato comprende un proveedor (110) y un procesador de señales (120). El proveedor (110) está adaptado para proporcionar primeras propiedades de covarianza de la señal de entrada de audio. El procesador de señales (120) está adaptado para generar la señal de salida de audio mediante la aplicación de una regla de mezcla en por lo menos dos de los dos o más canales de entrada de audio. El procesador de señales (120) está configurado para determinar la regla de mezcla sobre la base de las primeras propiedades de covarianza de la señal de entrada de audio y sobre la base de las segundas propiedades de covarianza de la señal de salida de audio, en donde las segundas propiedades de covarianza son distintas de las primeras propiedades de covarianza.
