In this paper, we propose a system to separate polyphonic musical sound and to estimate musical instruments using parallel connected resonator comb filters. The system devides polyphonic musical sound into harmonic components using comb filters. Then, the system estimates musical instruments from the auto-correlation functions of the separated harmonic components. To verify the efficiency of the system, we have conducted computer simulations. Exprimental results show that the proposed system is useful to estimate musical instruments.
