Abstract

The invention discloses an electronic music classification method and system based on multi-sound-source separation, and the method comprises the steps: reading a to-be-classified electronic music file, and extracting N representative sound sources through a sound source separation network; generating a spectrogram matrix from the separated N sound source files and the original koji through a short-time Fourier transform and harmonic / impact source separation technology; enabling the spectrogram matrix to obtain feature representation containing local information and time sequence information through a convolutional recurrent neural network (CRNN); and finally enabling the feature representation to pass through a plurality of full connection layers and softmax functions, and outputting thecategory of the to-be-classified electronic music. By adopting the method, the accuracy of electronic music classification can be greatly improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for classifying electronic music based on the separation of multiple sound sources. Background technique [0002] With the prevalence of electronic syllable festivals and electronic music culture, electronic music has long since shed its niche and experimental image, and has gradually entered the embrace of the mainstream music market. After the booming development since the 1970s, the genres of electronic music are constantly increasing. Wikipedia has included more than 200 types of subdivisions. Massive electronic music urgently needs to be classified to improve database management and achieve more. Customized behaviors, such as music retrieval, music recommendation, etc. [0003] In the process of implementing the present invention, the inventor of the present application found that the method of the prior art has at least the following technical problem...
