Abstract

Un aparato para procesar una señal de audio comprende un analizador de señal de audio y un filtro. El analizador de señal de audio se configura para analizar una señal de audio para determinar una pluralidad de valores de filtro de supresión de ruido para una pluralidad de bandas de la señal de audio, en donde el analizador se configura para determinar un valor de filtro de supresión de ruido de manera que un valor de filtro de supresión de ruido sea mayor o igual a un valor mínimo de filtro de supresión de ruido y de modo que el valor mínimo de supresión de ruido dependa de una característica de la señal de audio. El filtro se configura para filtrar la señal de audio, en donde el filtro se ajusta basándose en los valores del filtro de supresión de ruido.
