Abstract(in English) | An optimum filter for extracting harmonics from the mixture sound is derived as a result of the Maximum a Posteriori estimation. It has constant-Q pass-bands located on each harmonic frequencies and therefore assures robustness against the pitch estimation error. It is shown that the impulse response and its transfer function have similar form each other. Simulation results for noise suppression show good performance compared with the conventional comb filter. |
