Abstract
L'invention concerne un dispositif de commande de bruit de confort (50) servant à générer des paramètres de commande cn (bruit de confort). Un tampon (200) d'une taille prédéterminée est configuré pour stocker des paramètres cn pour des trames sid (descripteur d'insertion de silence) et des trames de maintien actif. Un sélecteur de sous-ensemble (50a) est configuré pour déterminer un sous-ensemble de paramètres cn pertinent pour des trames sid sur la base de l'âge des paramètres cn stockés et d'énergies résiduelles. Un extracteur de paramètres de commande de bruit de confort (50b) est configuré pour utiliser le sous-ensemble de paramètres cn déterminé afin de déterminer les paramètres de commande cn pour une première trame sid suivant une trame de signal actif.
