Abstract

La invención se refiere a un procedimiento de re-muestreo de una señal de audiofrecuencia en una codificación o decodificación de señal de audiofrecuencia. El procedimiento es tal que incluye las etapas siguientes por bloque de señal a re-muestrear: - determinación (E401) mediante predicción lineal adaptativa de un número de muestras de señal futura, siendo definido este número en función de un retardo de re-muestreo elegido; - construcción (E402) de un vector de soporte de re-muestreo a partir al menos de las muestras del bloque actual y de las muestras determinadas de señal futura; - aplicación (E403) de un filtro de re-muestreo sobre las muestras del vector de soporte de re-muestreo. La invención se refiere igualmente a un dispositivo de re-muestreo que implementa el procedimiento descrito, un codificador y un decodificador que comprende al menos un dispositivo.
