Original Kurzfassung:
In this paper, we present a Hidden Markov Model (HMM)
based beat tracking system that simultaneously extracts
downbeats, beat times, tempo, meter and rhythmic patterns.
Our model builds upon the basic structure proposed
by Whiteley et. al [9], which we further modified by introducing
a new observation model: rhythmic patterns are
learned directly from data, which makes the model adaptable
to the rhythmical structure of any kind of music. The
MIREX beat tracking evaluation - 30 results using ten measures
and three datasets - placed our algorithm among the
top three performing algorithms thirteen times and always
inside the top ten.
