Problem

• The ONU chapel operated an electronic carillon
  for several years.
• This system failed two years ago
• Rev. Vernon LaSala commissioned our Senior Design
  team to create a new PC based carillon system

Specifications

• Chapel carillon was expected to have
• Ability to add/remove sound files from the daily
  schedule.
• Default schedule to be played each day unless
  changes are made manually.
• Ability to save/load specific schedules.
• Option for disabling the system during certain
  hours.
• Display daily schedule in both text and graphical
  format.

Current Implementation Sound Files

• Bell Buddy supports only Wave (.wav) files in our
  system because they are uncompressed files and
  provide higher sound quality
• The Chaplin has purchased a PC specifically for
  our system, so the size of wave files is not a
  problem.

Current ImplementationPlaying Wave Files

• We discovered winmm.dll, which is a DLL file that
  handles low level joystick and sound functions.
• We used this this file from our code as opposed
  to writing our own media player software.

7
Current ImplementationTime Keeping

• The nature of our project necessitates that our
  system keep very precise time.
• We contacted the ONU IT department and confirmed
  that the correct time is sent to all machines on
  the campus network at regular intervals.

Melody Assistant

• Showcase program that allows users to enter a
  musical score, and convert it into a desired
  audio format.
• Supports the ability to import and define new
  instruments.
• We intend to create a carillon instrument
  within Melody Assistant.

  marketing our final product.

  only made available to people specifically
