ONU English Chapel:

Fake Bells

Electronic horns

problem
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
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
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 implementation playing wave files
Current Implementation:Playing 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.
current implementation time keeping
Current Implementation:Time 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
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.
the verdin agreement
The Verdin Agreement
  • Verdin required a representative to sign on behalf of ONU; unfortunately this led to several months of legal issues
  • Agreement signed in mid April
  • prevents us from independently patenting or marketing our final product.
  • obligated to ensure that Verdin’s sound files are only made available to people specifically associated with the project.
  • The sound files from Verdin have not yet arrived.
