Music generation method and device based on generative adversarial network

Abstract

The invention provides a music generation method and device based on the generative adversarial network and belongs to the technical field of artificial intelligence. The method includes steps that amusic training signal is obtained, the music training signal includes a multi-track polyphonic music real signal and multiple preset soundtrack music real signals; a feature matrix is extracted from the music training signal as music training sample data; a generative adversarial network model is constructed and trained to obtain network parameters of the trained generative adversarial network model; a random music signal inputted by a user is obtained; the random music signal is inputted to the generative adversarial network model, so the generative adversarial network model is made to automatically generate a multi-track polyphonic music signal according to the music random signal and the network parameters. The method is advantaged in that a problem that generating the polyphonic musiccoordinating among multiple soundtracks is difficult in the prior art is solved.

Description

【Technical field】 [0001] The invention relates to the technical field of artificial intelligence, in particular to a music generation method and device based on a generative confrontation network. 【Background technique】 [0002] Music is often composed of multiple instruments / tracks with their own temporal dynamics, where music unfolds interdependently over time. The successes of natural language generation and monophonic music generation are not easily generalizable to polyphonic music. Most existing techniques choose to simplify the generation of polyphonic music in some way to keep the problem manageable. Such simplifications include: generating only single-track monophonic music, introducing chronological ordering of notes for polyphonic music, etc. [0003] Therefore, how to generate coordinated polyphonic music among multiple audio tracks has become an urgent problem to be solved. 【Content of invention】 [0004] In view of this, an embodiment of the present invent...
