Real-time Visual Beat Tracking using a Comb Filter Matrix.
Andrew Robertson, AM Stark, Mark D. Plumbley · Surrey Research Insight Open Access (The University of Surrey) · 2011
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.
