Abstract

Un aparato para procesar una senal de audio para generar una senal extendida en ancho de banda que tiene una parte de alta frecuencia y una parte de baja frecuencia que usa datos paramétricos para la parte de alta frecuencia, los datos paramétricos que se relacionan con bandas de frecuencia de la parte de alta frecuencia comprenden un calculador de borde de parche (2302) para calcular un borde de parche tal que el borde de parche coincide con un borde de banda de frecuencia de las bandas de frecuencia. El aparato además comprende un parcheador (2312) para generar una senal parcheada usando la senal de audio (2300) y el borde de parche.
