Abstract  Abstract

According to the embodiments of the invention, an audio signal classification method and apparatus are provided for the classification of inputted audio signals. The method comprises the following steps: according to the sound activity of the current audio frequency frame, determining whether the frequency spectrum fluctuation of the current audio frequency frame is obtained and stored in a frequency spectrum fluctuation storage device or not wherein the frequency spectrum fluctuation represents the energy fluctuation of the frequency spectrum of the audio frequency signals; according to whether the sound frequency frame is beat music or the activity of the historical audio frequency frame, updating the frequency spectrum fluctuation stored in the frequency spectrum fluctuation storage device; and based on partial or all valid statistic data for the frequency spectrum fluctuation stored in the frequency spectrum fluctuation storage device, classifying the current audio frequency frame as a sound frame or a music frame.
