An audio decoding device (1) generates a first decoded audio from a first code string by a first decoding method. An audio encoding device (2) judges whether the first decoded audio is an audio signal or a non-audio signal by using the information contained in the first code string and generates a second code string by encoding the first decoded audio by the second encoding method according to the judgment. Thus, there are provided a device and a method for converting a code obtained by encoding audio by a certain method into a code decodable by the other method with a low calculation amount.
L'invention porte sur un décodeur audio (1) qui génère un premier audio décodé à parti d'une suite de codes selon un premier procédé de décodage. Un codeur audio (2) évalue si le premier signal audio décodé est un signal audio ou un signal non audio en utilisant les informations contenues dans la première suite de codes et génère une seconde suite de codes en codant le premier signal audio décodé selon le second procédé de codage conformément à l'évaluation. L'invention porte donc sur un dispositif et un procédé de conversion d'un code obtenu par codage audio selon un procédé donné en un code décodable par l'autre procédé avec un faible montant de calcul.
