Abstract

Un método para descodificación espectral de percepción comprende descodificación de coeficientes espectrales recuperados de un flujo binario en coeficientes espectrales descodificados de un juego inicial de coeficientes espectrales. El juego inicial de coeficientes espectrales se llenan con espectro. El llenado de espectro comprende llenado con ruido de agujeros espectrales ajustando coeficientes espectrales en el juego inicial de coeficientes espectral que no se están descodificando del flujo binario igual a elementos derivados de los coeficientes espectrales descodificados. El juego de coeficientes espectrales reconstruidos de un dominio de frecuencia formado por el llenado de espectro se convierte en una señal de audio de un dominio de tiempo. Un descodificador espectral de percepci6n comprende un rellenador de ruido, que opera de acuerdo con el método para descodificación espectral de percepción.
