n a nutshell, PhatBeat is a cross-platform (Linux and Windows) beat counter for use by collectors, producers, DJs, and others interested in beat-oriented music. For now it requires users to tap in the beat during listening, after which it calculates and displays the track's BPM and the size of a measure in seconds. Full details are available in the README file.
PhatBeat was begun in late 2002, and this release (version 1.0) was made in November of 2003. It is written in C++, and the GUI interface uses the SDL and SDL-Image libraries for display. PhatBeat is licensed under the GNU General Public License.
