Sinusoidal synthesis of music with extraction of information about music performances from music signals including a harsh noise

摘要

There are many rare recorded performances by famous artists, and most of their sound quality is very poor. The method extracting musical information (for example pitch, velocity, and so on) is useful to regenarate those musical performances. However, it has been very difficult to extract musical information from those music signals, becouse of some kinds of noise. In this paper, we propose the following method - expect a time the sound is performed using score information, and sarch out the sound. This method makes extraction of musical information from the music signals including noise possible.
