| Abstract(in English) | In this paper, we propose a method of the pitch frequency estimation and the estimation of playing musical instruments for a real musical sound using adaptive comb filters. The frequency components of the musical tone can be eliminated by comb filters, if zero points are corresponding to the pitch frequency. The real musical sound which is not synthesized has a difference of the pitch frequency from a standard temperament scales. In the proposed method,the positions of the zero points of an adaptive comb filter are changed as decreasing the amplitude of its output, and strict pitch frequencies can be estimated. We have done some computer simulations on transcribing the mixed sounds of the real musical tone. As a result, it is clear that the proposed method is useful to estimate pitch frequencies and musical instruments. |
