Abstract
La invención se refiere al procesamiento de una señal de audio digital, que incluye una serie de muestras distribuidas en tramas consecutivas; el procesamiento se implementa en particular cuando se descodifica dicha señal para reemplazar por lo menos una trama de señal perdida durante la descodificación; el método incluye los siguientes pasos: a) buscar, en un segmento de señal válido disponible cuando se descodifica, para por lo menos un periodo en la señal, determinado de acuerdo con dicha señal válida; b) analizar la señal en dicho periodo, para determinar componentes espectrales de la señal en dicho periodo; c) sintetizar por lo menos una trama para reemplazar la trama perdida, mediante la construcción de una señal de síntesis a partir de: una suma de componentes seleccionados de entre dichos componentes espectrales predeterminados, y un ruido agregado a la suma de componentes; en particular, la cantidad de ruido agregado a la suma de componentes se pondera de acuerdo con información de voz de la señal válida, obtenida cuando se descodifica.
