With the rapid popularization of the Internet and the wide application of audio compression technology, the effective combination of computer electronic audio processing technology and music has become the development trend of music analysis. In this paper, the instrument coding of music is realized through computer analysis coding method, and the analysis method of network model is constructed to realize the hierarchical feature analysis of computer music. Based on audio signal processing, Fourier transform, short-time Fourier transform and Meir transform are used to extract the acoustic features of music directly, and analyze the computer music structure features, which can save the analysis time and improve the accuracy of analysis. Finally, the music spectrum analysis test method is used to effectively realize the rationality of feature analysis, and the performance of the model is accurate.
