    Abstract: PURPOSE: An integrated voice/audio coding/decoding device for processing a window sequence based on mode switching is provided to differently perform a coding method corresponding to a property of an input signal, thereby maximizing coding performance and sound quality. CONSTITUTION: An integrated voice/audio coding/decoding device performs LPD(Linear Prediction Domain) mode switching for a sub-frame which comprises a frame of an input signal. The integrated voice/audio coding/decoding device codes the input signal by applying a window based on an LPD mode to a current sub-frame. The integrated voice/audio coding/decoding device applies the window to the current sub-frame. The window is changed corresponding to an LPD mode of a previous sub-frame and an LPD mode of a next sub-frame.
