Abstract(in English) | A concert is a live performance which consists of some performers. In a concert, each human performer can play the musical performance correspond to the other one, even if the performance includes uncertainty such as tempo fluctuation and mistakes. In this paper, we propose an automatic accompaniment system as an attempt to realize human-computer concerts, which follows the human performance and play the accompaniment correspond to the performance automatically. The capability of following a human performance is a problem to recognize and anticipate the score position in real-time by computer. It is called score following in the literature. In our study, we present a robust on-line algorithm for real-time audio-to-score alignment based on a delayed decision and anticipation framework by modeling human performances which include uncertainty such as tempo fluctuation and mistakes and developed an automatic accompaniment system which is capable of polyphonic music signal. |
