A Dynamic Programming Approach with Positional Weighting Window to Beat Tracking for Audio Music
نویسندگان
چکیده
Automatic beat tracking is challenging task, especially for audio music with time-varying meters. This study proposes a dynamic programming approach with positional weighting window to handle beat tracking with time-varying meters. In particular, the tempo curve is the reference to obtain correct beat positions. The weighting window is used to adapt bandwidth of tempo which reciprocal represents likelihood of beat position candidates. Combining with the strength of novelty curve, the beat tracking result of dynamic programming surpass those scores of other algorithms for MAZ dataset. The beat tracking algorithm outperforms eight out of ten performance indexes in MIREX2012 contest. Index Terms – Tempo Curve, Novelty Curve, Timevarying meter, Dynamic programming, Weighting Window

A Two-Fold Dynamic Programming Approach to Beat Tracking for Audio Music with Time-Varying Tempo
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 with Dynamic Programming
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 piec...
متن کاملA Multipath Architecture with Arbitrator for Beat Tracker
This study proposed multipath architecture for a dynamic (DP) programming approach to solve the problem of the uncertain starting points in dynamic programming. The starting points of those paths are selected from the local maximum of onset detection function and beginning interval of excerpts. We also utilize the tempi of tempo estimation to give the guidance of the beat tracking. Index Terms ...
