UNIFIED SPEECH/AUDIO CODER(USAC) PROCESSING WINDOWS SEQUENCE BASED MODE SWITCHING

摘要

integrated voice / audio section / decoder is disclosed for processing a window based on the mode switching sequence . When integrated voice / audio part / decoder mode switching occurs , it is possible to perform the frame-to-frame overlap , based on the folding point to be coded or decoded . Integrated voice / audio part / decoder by processing the other window sequence according to circumstances to carry out the coding or decoding , it is possible to improve the coding performance . ;
