INTEGRATED VOICE/AUDIO ENCODING/DECODING DEVICE AND METHOD WHEREBY THE OVERLAP REGION OF A WINDOW IS ADJUSTED BASED ON THE TRANSITION INTERVAL

WIPO Patent Application WO/2011/046329

A2

Disclosed is an integrated voice/audio encoding/decoding apparatus whereby the overlap region of a window is adjusted based on the transition interval. In the present invention, encoding is carried out by making windows of relatively long length overlap in order to increase the efficiency of encoding, while the overlap region of the windows is reduced in accordance with the transition interval when there is a transition interval between frames, thereby making it possible to reduce the occurrence of noise due to transition intervals.
