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 receiving, by an audio processing apparatus, coding identification information indicating whether to apply a first coding scheme or a second coding scheme to a current frame, when the coding identification information indicates that the second coding scheme to the current frame, receiving window type information indicating a particular window for the current frame, from among a plurality of windows; identifying that a current window is a long-start window based on the window type information, wherein the long-start window follows only-long window of a previous frame, wherein the long-start window includes a gentle long-start window and a steep long-start window; and, when the first coding scheme is applied to a following frame, applying the gentle long-start window to the current frame, wherein: the gentle long-start window comprise a descending line with first slope, the steep long-start window comprise a descending line with second slope, the first slope is gentler than the second slope. |
