| Abstract(in English) | We propose the pitch estimation algorithm based on comb filters for construction of the automatic transcription system. However, a duration estimation which determines a length of each note, and a beat tracking to estimate tempo and beat of a music are necessary for an automatic transcription system other than a pitch estimation. In this paper, a musical data of piano is processed by STFT (Short-Time Fourier Transform), and the note connection processing required for a duration estimation is considered using time jitters of magnitude spectra. As the experimental result, the note connection processing was realized with the accuracy of 91.9%. |
