Abstract
La invención se refiere al procesamiento de una señal, la señal que comprende una serie de muestras distribuidas en bloques consecutivos. El procesamiento se lleva a cabo durante la decodificación de tal señal con el fin de remplazar por lo menos un bloque de señal perdido durante la decodificación y comprende en particular las siguientes etapas: a) buscar (S3), en una señal válida disponible para decodificación, un segmento de señal que tiene una duración que corresponde a un periodo determinado en la base de dicha señal válida; b) analizar espectrales del segmento; y c) sintetizar (S6) por lo menos un bloque para remplazar el bloque perdido, mediante construcción de una señal de síntesis de por lo menos una porción de los componentes espectrales.
