Abstract

Un aparato (100) para generar datos de salida del ancho de banda (102) para una señal de audio (105) que comprende un medidor del piso de ruido (110), un caracterizador de energía de la señal (120) y un procesador (130). La señal de audio (105) comprende componentes en una primera banda de frecuencia (105a) y componentes en una segunda banda de frecuencia (105b), los datos de salida del ancho de banda (102) están adaptados para controlar una síntesis de los componentes en la segunda banda de frecuencia (105b). El medidor del piso de ruido (110) mide los datos del piso de ruido data (115) de la segunda banda de frecuencia (105b) para una porción de tiempo (T) de la señal de audio (105). El caracterizador de energía de la señal (120) deriva los datos de distribución de energía (125), los datos de distribución de energía (125) caracterizan una distribución de energía en un espectro de la porción de tiempo (T) de la señal de audio (105). El procesador (130) combina los datos del piso de ruido (115) y los datos de distribución de energía (125) para obtener los datos de salida del ancho de banda (102).
