Abstract
A method, medium, and apparatus encoding/decoding audio data in which audio data is hierarchically encoded, and at least one extension data of the audio data is encoded using at least one encoding method, and decoding is performed in the same manner, thereby ensuring fine grain scalability (FGS) and unlimited extendibility of the audio data.
