Introduction

• Why did we choose an audio editor as our project?
• Why did we choose to use Linux for development
  purposes?
• Why did we choose GTK as our windowing toolkit?

Overview (What is LAMP?)

• A program used to edit audio files of various
  formats
• Features the ability to dynamically load filters
  and sound generation libraries
• Intuitive, graphical user interface
• Open source

Utility Module

• Provides the GUI with an abstract interface to
  the lower-level modules
• File management

Project Difficulties

• Interaction of the different modules
• Learning the APIs for the different libraries we
  used
• Efficient management of audio data
• Graphical interaction with audio file data
• Personal conflicts
