Abstract

Un aparato para procesar una señal de audio comprende un separador para separar una primera porción de un espectro de la señal de audio de una segunda porción del espectro de la señal de audio, la primera porción que tiene una primera característica de señal y la segunda porción que tiene una segunda característica de señal. El aparato comprende un primer extensor de ancho de banda para extender un ancho de banda de la primera porción utilizando primeros parámetros asociados con la primera característica de señal, para obtener una primera porción extendida y comprende un segundo extensor de ancho de banda para extender un ancho de banda de la segunda porción utilizando segundos parámetros asociados con la segunda característica de señal, para obtener una segunda porción extendida. El aparato comprende un combinador configurado para utilizar la primera porción extendida y la segunda porción extendida para obtener una señal de audio combinada, extendida.
