Abstract
Se da a conocer un aparato para generar una o más señales de canales de salida de audio dependiendo de dos o más señales de canales de entrada de audio. Cada una de las dos o más señales de canales de entrada de audio comprende porciones directas de la señal y porciones ambiente de la señal. El aparato comprende una unidad de determinación de filtros (110) para determinar un filtro mediante la estimación de una primera información de densidad espectral de potencia y mediante la estimación de una segunda información de densidad espectral de potencia. Asimismo, el aparato comprende un procesador de señales (120) para generar la mencionada una o más señales de canales de salida de audio mediante la aplicación del filtro a las dos o más señales de los canales de entrada de audio. La primera información de densidad espectral de potencia indica la información de densidad espectral de potencia sobre las dos o más señales de los canales de entrada de audio y la segunda información de densidad espectral de potencia indica la información de densidad espectral de potencia sobre las porciones de señal ambiente de las dos o más señales de canales de entrada de audio. O bien la primera información de densidad espectral de potencia indica la información de densidad espectral de potencia sobre las dos o más señales de los canales de entrada de audio y la segunda información de densidad espectral de potencia indica la información de densidad espectral de potencia sobre las porciones directas de señal de las dos o más señales de canales de entrada de audio. O bien la primera información de densidad espectral de potencia indica la información de densidad espectral de potencia sobre las porciones directas de señal de las dos o más señales de canales de entrada de audio y la segunda información de densidad espectral de potencia indica la información de densidad espectral de potencia sobre las porciones de señal ambiente de las dos o más señales de canales de entrada de audio.
