BeatComber Beat tracker for live input This is described in an ICMC 2011 paper - on beat tracking with a comb filter matrix. There's some interactive functionality. You can restrict the areas it will look in - eg 100 to 140 bpm - by narrowing the graph. You can also choose the current beat by clicking on the graph, and see th current output.
