It's a simple metronome, for understanding bpm of a song by manual tap. It's not written well, it works but it's only a "programming toy", I'm not a real developer and I'm still learning c++/ Qt and I wanted to know how sourceforge work, seeing "from the other side of the screen" :) . Program uses Qtimers, Qtime, many signal mapping objects, a simple system bell...and a bunch of other ui controls. So...play with it :) Turn system volume down, no volume control is enabled in this release!...
