- W2372334579 abstract "To solve the partial overlapping problem in polyphonic music effectively,a multiple-f0 estimation method based on the timbre model is proposed.After the time-frequency feature of the timbre is analyzed,it is pointed out that the harmonic structure in delay and sustain state is stable and suitable for fundamental frequency estimation.The candidate f0 is selected according to the harmonic matching rate and the strength,and the exact f0 is determined using the spectrum iterative subtraction method.The spectral line is subtracted based on the minimum harmonic matching rate,and the partial overlapping problem is solved applying the proportional subtraction mechanism.The simulation experiments and actual music testing show that this algorithm is accurate,and can be applied widely to music signal analysis with stable harmonic structure." @default.
