Abstract[English]
The invention relates to a method for post-processing a decoded audio signal, wherein the post-processing (603) applies a post-processing model resulting from a training phase (602) carried out between a reference signal (x'), obtained by applying at least one pre-processing operation (601) to an input signal (x), and a decoded output signal (y'). The invention also relates to a post-processing device implementing the method.[French]
L'invention se rapporte à un procédé de post-traitement d'un signal audio décodé, dans lequel le post-traitement (603) applique un modèle de post-traitement issu d'une phase d'entrainement (602) réalisé entre un signal de référence (x') obtenu par l'application d'au moins un prétraitement (601) à un signal d'entrée (x) et un signal décodé de sortie (y'). L'invention se rapporte également à un dispositif de post-traitement mettant en œuvre le procédé.
