Abstract

Un aparato para calcular la ampliacion de los datos de ancho de banda de una senal de audio en un sistema de ampliacion de ancho de banda, en el cual una primera banda espectral está codificada con un primer numero de bits y una segunda banda espectral distinta de !a primera banda espectral está codificada con un segundo numero de bits que más pequeno que el primer numero de bits, donde dicho aparato tiene una calculadora de parámetros de ampliacion de ancho de banda controlable (10) para calcular parámetros de ampliacion de ancho de banda para la segunda banda de frecuencia de un modo de tipo cuadro para una secuencia de cuadros de la senal de audio. Cada cuadro tiene un instante de tiempo de inicio controlable. El aparato comprende adicionalmente un detector de pendiente espectral (12) para detectar una pendiente espectral en una parte de tiempo de la senal de audio y para senalar el instante de tiempo de inicio para los cuadros individuales de la senal de audio dependiendo de la pendiente espectral.
