An audio encoding device (2) judges wheth er the first decoded audio is an audio signal or a non-audio signal by using th e 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 fo r converting a code obtained by encoding audio by a certain method into a code decodable by the other method with a low calculation amount.
