METHOD, MEDIUM, AND APPARATUS TO CLASSIFY FOR AUDIO SIGNAL, AND METHOD, MEDIUM AND APPARATUS TO ENCODE AND/OR DECODE FOR AUDIO SIGNAL USING THE SAME |
摘要 |
Provided are a classifying method and apparatus for an audio signal, and an encoding/decoding method and apparatus for an audio signal using the classifying method and apparatus. In the classification method, an audio signal is classified by adaptively adjusting a classification threshold for a frame of the audio signal that is to be classified according to a long-term feature of the audio signal, thereby improving a hit rate of signal classification, suppressing frequent mode switching per frame, improving noise tolerance, and providing smooth reconstruction of the audio signal.
