The Research Of Music Data Features Analysis And Extractive Techniques

Both flute and bamboo flute belong to the wind instrument with transverse blowing edge tone and they are often used in comparative studies.With the development of science and technology,the development and application of many acoustic analysis software bring convenience to the research of flute and bamboo flute.Currently,the popular research object at home and abroad "music information retrieval" includes the analysis and extraction techniques of music data features.In view of this research status,this paper hopes to summarize the previous relevant work,explores the new representation of music information difference degree parameter,enrichs the music characteristic technology theory,deepens the researchers' understanding of the similar instrument difference degree,quickly grasps the correlation between the instrument characteristic structure,and facilitates the sound quality improvement of Musical Instruments.The paper consists of five parts:The first part is an introduction.It focuses on the research status of music information retrieval at home and abroad,including the research background and significance,research work,innovation and contribution,and organizational structure.The second part is Chapter 1.The research on music information is summarized,mainly focusing on the basic concept,content and function of music information.The third part is Chapter 2.This paper summarizes the research on music data characteristics,discusses the concept and classification of music data characteristics,the traditional Fourier analysis and wavelet analysis techniques,and the emerging spectral envelope extraction and MFCC extraction techniques.The fourth part is Chapter 3.It is an experimental exploration of traditional analysis technology and emerging extraction technology,mainly focusing on the basic overview of flute and bamboo flute,the research results of the Fourier analysis technology and the MFCC extract technology.The fifth part concludes the thesis and puts forward the prospect of future research content.
