METHOD AND APPARATUS FOR ENCODING/DECODING STEREO AUDIO

摘要

PURPOSE: A method and a device for encoding/decoding a stereo audio are provided to reduce the number of additional information necessary for encoding/decoding processes, thereby increasing efficiency. CONSTITUTION: An audio encoding device includes a mono audio generating unit(110), an additional information generating unit(120), and an encoding unit(130). The mono audio generating unit generates divided audios during a process of generating a final mono audio. The encoding unit encodes the final mono audio generated by the mono audio generating unit and additional information generated by the additional information generating unit.
