Beat Tracking with Dynamic Programming
نویسنده
چکیده
There are many applications for which we would like to be able to track the ‘beat’ of a piece of recorded music – analogous to a listener’s foot-tapping. This paper describes our beat-tracking system, which operates by first estimating a global tempo (via autocorrelation of an ‘onset strength’ signal), then using dynamic programming to find the best sequence of beat times through the whole piece that both places beats on moments of high ‘onset strength’, as well as maintaining a spacing between beats that agrees with the global tempo. This system has been submitted to the 2006 MIREX Audio Tempo Extraction and Audio Beat Tracking competitions.

Automatic beat tracking and tempo estimation are challenging tasks, especially for audio music with timevarying tempo. This paper proposes a two-fold dynamic programming (DP) approach to deal with beat tracking with time-varying tempo. In particular, the first DP computes the tempo curve from the tempogram. The second DP identifies the optimum beat positions from the novelty and tempo curves. E...

متن کاملBeat Tracking by Dynamic Programming
Beat tracking – i.e. deriving from a music audio signal a sequence of beat instants that might correspond to when a human listener would tap his foot – involves satisfying two constraints: On the one hand, the selected instants should generally correspond to moments in the audio where a beat is indicated, for instance by the onset of a note played by one of the instruments. On the other hand, t...

This study proposed a weighting function for a dynamic (DP) programming approach as the cost function to handle beat tracking. The function is utilized to adapt bandwidth of tempo deviation which reciprocal represents likelihood of relative beat position.
