Proposals of MIDI coding and its application for audio authoring

We propose applying MIDI technology to coding of physiologic sounds such as heart sounds used in medical diagnosis for constructing medical audio databases. Furthermore, we extend our encoding algorithm in order to apply it to other types of sounds such as bird sounds and human singing. We overview our proposed encoding algorithms, which consist of a real time coding method and a high precision coding method. Then we present several coded examples applied for three typical categories: heart sounds, bird sounds and singing sounds. Finally, as our conclusion and future work, we propose an effective audio authoring application concept utilizing MIDI coding, which will be able to provide for conventional waveform editing, as much flexibility as MIDI editing
