Review of Musical Instrument Recognition in Music Information Retrieval

Efficient and accurate instrument recognition technology can effectively promote the in-depth development of sound source separation, music spectrum recognition, music genre classification and other research, and can be widely used in many fields, such as playlist generation, acoustic environment classification, instrument intelligent teaching and interactive multimedia. In recent years, with the continuous advancement of musical instrument recognition research, the performance of musical instrument recognition system has been greatly improved, but there are still many problems, such as difficult recognition of some musical instruments, difficult extraction of musical instrument audio features, and low recognition accuracy of complex musical instrument. How to identify musical instruments efficiently and accurately with the help of artificial intelligence technology has become the focus and difficulty of current research. According to the current research status, this paper summarizes the commonly used audio features, musical instrument recognition models and methods and commonly used data sets of musical instrument recognition, and summarizes the limitations and future develo-pment trend of the current research, so as to provide some reference for the research of musical instrument recognition.
