There is also some Kalman filtering to smoothen things a bit.\nWhen some reasonable beat duration is inferred, the tempo is shown on the\nscreen. Slow tempos are somewhat tracked, faster tempos not so much :(\n\nThe program does not require any special controls, but you can press key `d`\nto hide the visual tracking information. Pressing `m` toggles a visual\nmetronome that does not work nearly as well as it should; beat phase seems\nto be harder to grasp.\n\n[1]: http://openframeworks.cc\n[2]: https://github.com/kylemcdonald/ofxCv\n[3]: http://opencv.org\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjavidcf%2Fbobblehead","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjavidcf%2Fbobblehead","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjavidcf%2Fbobblehead/lists"}
