Short description of SchoolBell 5.0: SchoolBell plays sounds at specified times. It can be used to control the sound system of a school or factory break bells. Supported sound file formats are WAV, MP3 and MID. Different sounds can be defined for special events. Sounds can be faded out after a specific time, so standard music files can be used! Different tables allow non-standard schedules on some days (for instance on friday).
