The following sound examples include the acoustic input signal and the MIDI transcriptions produced with the proposed method. For each example, we show a score image of the transcription. The score images are automatically generated from the transcription MIDI files by using Lilypond music score typesetter. Please notice that the notes are not temporally quantized so that the score typesetting could be done unambiguously. The score images give some idea on the transcriptions, but they are not accurate in timing and assume time signature to be always 4/4. The input files are from the RWC (Real World Computing) popular and genre music databases.
