Study on accurate estimation of musical information in musical performance

Although the recent research in the field of Automatic music transcription has been active, there are still outstanding problems. Amongst, we focused on note-length and aim to estimate note-length exactly. In the past, Fourier or Wavelet transform are used to transform music signal into frequency domain. However, these transform can lose accuracy in time component. In this paper, we estimate tone duration from music signal without transforming it into frequency domain.
