Real-time Visual Beat Tracking using a Comb Filter Matrix

This paper describes an algorithm for real-time beat tracking with a visual interface. Multiple tempo and phase hypotheses are represented by a comb filter matrix. The user can interact by specifying the tempo and phase to be tracked by the algorithm, which will seek to find a continuous path through the space. We present results from evaluating the algorithm on the Hainsworth database and offer a comparison with another existing real-time beat tracking algorithm and offline algorithms.
