On-line Music Beat Tracking with Kalman Filtering and Probability Data Association (KF-PDA)
An on-line music beat tracking algorithm with Kalman filtering (KF) and probability data association (PDA) is proposed. The KF-PDA method not only estimates the music tempo and beat pulse positions in real-time but also provides a temporal metrical unit for human-perception-like processing. The superior performance of the proposed KF-PDA beat tracking system is demonstrated using the MIREX beat tracking competition's practice data set.
