Computer analysis and automatic recognition technology of music emotion

Abstract

The development of computer technology, multimedia technology and communication technology has made the application of computers more and more widespread in people's lives. The next direction of computer development is to expect to be able to use computers to analyze, simulate and express human subjective thinking activities. As a part of people's lives, music has a strong emotional appeal. The stronger the musical emotion, the more audiences representing the song. Most of the computer technology related to music is still in the storage, tuning, compression, etc. of music, but with the development of computer analysis and automatic recognition technology, today’s computer technology can already realize the cognition of music emotions through models and programs and creation. This article first briefly introduces computer analysis and automatic recognition technology, then analyzes and discusses the current representation model of music emotion recognition, and finally tries to design a music emotion recognition model design and proposes to introduce BP neural network into music emotion recognition technology to realize the automatic emotion analysis and recognition of the main music track.
