An Approach for Heartbeat Sound Transcription

This paper presents a heart sound transcription technique to provide semi-structured musical data. The heart beat samples were captured using stethoscope and recorded in pulse-code modulation (PCM) method into several differing audio file formats. Pitch tracking algorithm were utilized for the heartbeat transcription into MIDI generation. We propose the use of several sound processing techniques to improve the transcription. Several experiments using a collection recorded heartbeats illustrate the feasibility of using this note transcription approach in heart sound.
