Abstract

La presente tecnología se refiere a un dispositivo y a un método de procesamiento acústico y un programa, que hacen posible realizar una reproducción de audio con una calidad de sonido más alta. Este dispositivo de procesamiento acústico está provisto de: una primera unidad de procesamiento de representación que realiza un procesamiento de representación en función de una señal de audio para generar una primera señal de audio de salida para emitir sonido por medio de una pluralidad de primeros altavoces; y una segunda unidad de procesamiento de representación que realiza un procesamiento de representación en función de la señal de audio para generar una segunda señal de audio de salida para emitir sonido por medio de una pluralidad de segundos altavoces que tienen una banda de reproducción diferente a los primeros altavoces. La presente tecnología puede aplicarse a sistemas de reproducción de audio.
