Automatic transcription of piano music - Examples

Back to main demo page

Here are some transcription examples obtained with the system described in the paper Automatic transcription of piano music based on HMM tracking of jointly-estimated pitches, by Valentin Emiya, Roland Badeau and Bertrand David, to be presented and published to EUSIPCO'08.

Original audio is synthesized from MIDI files available at http://www.piano-midi.de/, using high quality piano synthesis softwares. The automatic transcription system takes the original audio files as its inputs and generates MIDI files. Original and transcription MIDI files are compared in terms of F-measure, precision and recall rates and mean overlap ratio. Transcription results can be appreciated as well by listening to and comparing the original audio and the from automatic transcription resynthesized audio.

Note that only pitches, onset and offset times are estimated/transcribed. Intensity of notes are set to a constant, medium value in the resynthesized audio files.
