Abstract

The embodiment of the invention provides an audio classifying method and device. The method comprises the steps that Pitch detection is carried out on an audio file to be classified, so as to acquire the Pitch sequence of the audio file; according to the Pitch sequence, the tonic of the audio file is searched; and according to the tonic of the audio file, mode detection is carried out on the audio file to determine the classification of the audio file. According to the invention, the classifying cost of the audio file can be reduced; the classifying efficiency is improved; and the intelligence is enhanced.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to the technical field of audio processing, in particular to a method and device for classifying audio files. Background technique [0002] Mode refers to a number of musical tones of different heights, which are organized around a certain central tone with a sense of stability according to a certain interval relationship to form an organic system. This system is called the mode, and the central tone is called the tonic. Audio files can be divided into major and minor categories according to the mode. Generally, the audio files of the major category are bright, lively and aggressive; the audio files of the minor category are soft and dark. At present, the traditional classification of audio files is usually manual, that is, it is necessary to manually listen to the content of the audio file to determine the category of the audio file; this classification method has high...
