Abstract

Un método para recuperación de espectro en descodificación espectral de una señal de audio, comprende obtener (210) de un juego inicial de coeficientes espectrales que representan la señal de audio, y determinar (212) una frecuencia de transición. La frecuencia de transición está adaptada a un contenido espectral de la señal de audio. Los agujeros espectrales en el juego inicial de coeficientes espectrales inferiores a la frecuencia de transición se llenan con ruido (214) y el juego inicial de coeficientes espectrales son extendidos en anchura de banda (216) por encima de la frecuencia de transición. También se ilustran los descodificadores y codificadores que están dispuestos para realizar parte de o el método completo.
