Beat 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...
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 کاملGreedy can also beat pure dynamic programming
Many dynamic programming algorithms are “pure” in that they only use min or max and addition operations in their recursion equations. The well known greedy algorithm of Kruskal solves the minimum weight spanning tree problem on n-vertex graphs using only O(n logn) operations. We prove that any pure DP algorithm for this problem must perform 2 operations. Since the greedy algorithm can also badl...
متن کاملOptimal radial contour tracking by dynamic programming
A common problem in most active contour methods is that the recursive searching scheme can only return a local optimal solution. Furthermore, the internal energy of the snake is not strong enough to control the shape of the contour. To overcome these difficulties, in this paper, we develop a causal internal energy term based on a radial contour representation to encode the smooth constraint of ...
متن کاملA Dynamic Programming Approach with Positional Weighting Window to Beat Tracking for Audio Music
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 represent...
