Multi-pitch Estimation Based on Partial Event and Support Transfer

Transcribed Results for Synthesized Ensemble Music Data:

Note that the goals of our method are to estimate the frequencies, onset and offset times of concurrent notes, rather than the timbre information. Therefore, please compare the Original .mid file with the Transcribed .mid file, which both discard the timbre information.

(1) A four part wood chamber music (flute, oboe, clarinet, basson)
Original .wav file synthesized from MIDI. It is the input of our method.
1_Wood_Oringin.wav(816 K)

Original .mid file.
1_Wood_Oringin.mid(492 Bytes)

Pianoroll of the original music:

Transcribed .mid file.
1_Wood_Trans.mid(462 Bytes)

Pianoroll of the transcribed result:

 

(2) A four part brass chamber music (trumpet, french horn, trombone, tuba)

Original .wav file synthesized from MIDI. It is the input of our method.
2_Brass_Oringin.wav(868K)

Original .mid file.
2_Brass_Oringin.mid(386 Bytes)

Pianoroll of the original music: 

Transcribed .mid file.

2_Brass_Trans.mid(318 Bytes)

Pianoroll of the transcribed result:

Compared with those in the original pianorolls, some notes are missing and some fake notes are detected. However, these errors are mostly octave errors, which are common in the MPE problem. In addition, these errors do not affect the quality of the re-synthesize audios severely. Compared with the original midi file, the transcribed results are rather good.
