Document Type and Number:
WIPO Patent Application WO/2004/095424
Kind Code:
A1
Abstract:
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.
