SIGNAL CLASSIFYING METHOD AND DEVICE, AND AUDIO ENCODING METHOD AND DEVICE USING SAME |
摘要 |
The present invention relates to an audio encoding and, more particularly, to a signal classifying method and device, and an audio encoding method and device using the same, which can reduce a delay caused by an encoding mode switching while improving the quality of reconstructed sound. The signal classifying method may comprise the steps of: classifying a current frame into one of a voice signal and a music signal; determining, on the basis of a characteristic parameter obtained from multiple frames, whether a result of the classifying of the current frame includes an error; and correcting the result of the classifying of the current frame in accordance with a result of the determination. By correcting an initial classification result of an audio signal on the basis of a correction parameter, the present invention can determine an optimum encoding mode for the characteristic of an audio signal and can prevent frequent encoding mode switching between frames. |
