An apparatus for decoding (100) an encoded audio signal (102). A first decoder (110a) decodes a first portion (104a) in accordance with a first decoding algorithm for a first time portion of the encoded signal (102) to obtain a first decoded signal (114a). A second decoder (110b) decodes a second portion (104b) in accordance with a second decoding algorithm for a second time portion of the encoded signal (102) to obtain a second decoded signal (114b). A BWE module (130) has a controllable crossover frequency (fx) and is configured for performing a bandwidth extension algorithm using the first decoded signal (114a) and BWE parameters (106) for the first portion (104a), and for performing a bandwidth extension algorithm using the second decoded signal (114b) and the bandwidth extension parameters (106) for the second portion (104b). A controller (140) controls the crossover frequency (fx) for the BWE module (130) in accordance with a coding mode information (108).

L'invention concerne un appareil de décodage (100) dun signal audio encodé (102). Un premier décodeur (110a) décode une première partie (104a) selon un premier algorithme de décodage pour une première partie temporelle du signal encodé (102) pour obtenir un premier signal décodé (114a). Un second décodeur (110b) décode une seconde partie (104b) selon un second algorithme de décodage pour une seconde partie temporelle du signal encodé (102) pour obtenir un second signal décodé (114b). Un module BWE (130) a une fréquence de croisement contrôlable (fx) et est configuré pour exécuter un algorithme d'extension de bande passante en utilisant le premier signal décodé (114a) et des paramètres BWE (106) pour la première partie (104a), et pour exécuter un algorithme d'extension de bande passante en utilisant le second signal décodé (114b) et les paramètres d'extension de bande passante (106) pour la seconde partie (104b). Un contrôleur (140) commande la fréquence de croisement (fx) pour le module BWE (130) conformément à des informations de mode de codage (108).
