Civil song intelligent auxiliary composition system and method based on up-down sampling

Abstract

The invention discloses a civil song intelligent auxiliary composition system and method based on up-down sampling. The civil song intelligent auxiliary composition system comprises a data storage module, a preprocessing module, an up-down sampling module, a music training module, a motivation generation module, a composition module, a down-down sampling module and a midi synthesis module. The data storage module is used for storing various music data; the preprocessing module converts the music into a unified mode; the up-down sampling module upsamples the pitch sequence to obtain an upsampling sequence; the music training module learns national style music to obtain a trained network model; the motivation generation module is used for generating a motivation pitch sequence; the composition module generates a composition pitch sequence in combination with the motivation pitch sequence and a trained network model; the down-down sampling module downsamples the composition pitch sequenceto obtain a pitch sequence and a corresponding time value sequence; and the midi synthesis module synthesizes the pitch sequence and the corresponding time value sequence into midi audio and outputsthe midi audio. The civil song intelligent auxiliary composition system and method can assist in creation and generate the music of the ethnic style loved by the user.

Description

technical field [0001] The invention relates to the technical fields of music-assisted composition and machine learning, and in particular to an intelligent auxiliary composition system and method for folk songs based on up-and-down sampling. Background technique [0002] With the improvement of social and economic level, people put forward higher requirements for spiritual life. Because of its strong appeal, music can not only cultivate sentiment and relieve mood, but even have a good regulating effect on some mental diseases. Composers are trying different new methods and forms to create music, but the production cost of professional music is too high, and the threshold for ordinary users to compose is too high. With the rapid development of deep learning and machine learning, automatic computer composition can greatly improve the creativity of music. While assisting composers to develop new creative ideas, it can also meet the needs of the public for entertainment. [0...

AI Technical Summary

Problems solved by technology

[0004] At present, computer-aided composition technology is relatively mature abroad. In summary, the main algorithms involve Markov chain, knowledge base rule system, music grammar, artificial neural network and genetic algorithm. Each composition algorithm has its own advantages and limitations. The problem is that due to the late start of domestic research on computer composition systems, there is no mature analysis and creation of automatic composition for Chinese folk music. Therefore, it is urgent to propose an intelligent auxiliary composition system for folk songs based on up-and-down sampling.
