摘要

The MIDI interface is originally designed for electronic musical instruments but we consider this music-note based coding concept can be extended for general acoustic signal description. At first we proposed applying the MIDI technology to coding of bio-medical auscultation sound signals such as heart sounds. Then we have tried to extend our encoding target and improve the coding precision based on Generalized Harmonic Analysis in order to apply it to vocal sounds. Currently, we are trying to separate each tone included in popular songs and encode both vocal sounds and several background instrumental sounds into separate MIDI channels. Using a GM-standard MIDI tone generator, we can playback this multi-channel MIDI encoded data including vocal sounds. In this paper, we present an abstract algorithm of our developed MIDI software encoder tool, being used for producing interactive general audio contents controlled by MIDI.
