A METHOD AND AN APPARATUS FOR PROCESSING AN AUDIO SIGNAL

摘要

An apparatus for processing an audio signal and method thereof are disclosed. The present invention includes when a second coding scheme is applied to a current frame, receiving, by an audio processing apparatus, window type information indicating a particular window for the current frame from among a plurality of windows; and, applying a current window to the current frame based on the window type information, wherein, when a first coding scheme is applied to a previous frame, the plurality of window consists of a short window, a first transition window, a second transition window, wherein the short window has at least one ascending line which width is N/8, and the first transition window and the second transition window have an ascending line which width is N/4 (where N is frame length).
