I used to have an MP3 DJ'in program which could (somewhat decently)detect the BPM of a track, and attempt to match two songs' BPMs in order to create a smooth transition.
But I haven't found a Windows app which could determine the BPM of a track to the accuracy needed to create steps. Anyone seen a decent app for that?
