Flexible Harmonic Temporal Structure for Modeling Musical Instrument

Abstract : Multipitch estimation is an important and difficult problem in entertainment computing. In this paper a flexible harmonic temporal structure for modeling musical instrument was proposed for estimating pitch in real music. Unlike the previous research, the proposed model does multipitch estimation according to the specific characteristics of specific musical instrument and uses EM algorithm to estimate the parameters in the model. Through choosing parameters suitable for its own characters for specific instrument, the proposed model preponderated over the common model.
