Abstract

Un aparato para generar una senal mejorada a partir de una senal de entrada (600), en donde la senal mejorada tiene valores espectrales para una region espectral de mejora, donde los valores espectrales para las regiones espectrales de mejora no estan contenidos en la senal de entrada (600), que comprende un mapeador (602) para mapear una region espectral de la fuente de la senal de entrada en una region de destino en la region espectral de mejora, donde la region espectral de la fuente comprende una region de relleno de ruido (302); y un rellenador de ruido (604) configurado para generar primeros valores de ruido para la region de relleno de ruido (302) en la region espectral de la fuente de la senal de entrada y para generar segundos valores de ruido para una region de ruidos en la region de destino, en donde los segundos valores de ruido se decorrelacionan de los primeros valores de ruido o para generar segundos valores de ruido para una region de ruidos en la region de destino, en donde los segundos valores de ruido se decorrelacionan de primeros valores de ruido en la region de fuente.
