Description of Project Goals

• Develop software to improve choral groups
• Goals
• Develop a program that can aid vocalists in
  producing a stronger overtone
• Build a simple but useful software interface
• Design the program to run in real-time
• Write the program using robust, efficient code
• Software Modular design
• Document the program

4
Alternate Designs

• CakeWalk
• Problems with Cakewalk, it didnt run in
  real-time
• Microsoft Windows wave mapper
• Would not support four channels

5
Final Design

• DirectX API
• Wide range of compatible hardware
• Supported in future Windows versions

6
Final Design (contd.)

• Windows GDI
• Hardware independent
• Simple implementation

7
Final Design (contd.)

• Visual C 6.0
• Performance
• Modular implementation
