SchoolBell plays sounds at specified times. It can be used
to control the sound system of a school or business.
Supported sound file formats are Wave, MP3 and MIDI.
Different sounds can be defined for special events. Sounds
can be faded out after a specific time, so normal music
files can be used! Different tables allow non-standard
schedules on some days (for instance on friday). The system
time can be synchronized via internet. SchoolBell can start
automatically and run minimized, so the computer can be
used for other tasks!
