We have developed a beat tracking system, called BTS , that processes acoustic signals of music and recognizes temporal positions of beats in real time. Beat tracking is an important initial step in computer emulation of human music understanding, since beats are fundamental to the perception of music. BTS deals with popular music, particularly rock and pop music in which drums maintain the beat. Because our system examines multiple hypotheses in parallel, it can follow beats without losing track of them, even if some hypotheses become wrong. BTS has been implemented on a parallel computer, the Fujitsu AP1000, to handle this computationally intensive task in real time.
