Abstract  Abstract

The embodiment of the invention discloses an audio signal classification method and device. The method and the device are used for classifying input audio signals. The method comprises the following steps that according to the sound activity of the current audio frame, whether the spectrum fluctuation of the current audio frame is obtained or not is determined and is stored into a spectrum fluctuation memory, wherein the spectrum fluctuation shows the spectrum energy fluctuation of audio signals; according to the result that whether the audio frame is beat music or the activity of the historical audio frames or not, the spectrum fluctuation stored in the spectrum fluctuation memory is updated; according to the statistical magnitude of partial or all effective data of the spectrum fluctuation stored in the spectrum fluctuation memory, the current audio frames are classified into voice frames or music frames.
