Audio Effects presentations.

   * About 10 mins
   * Explain
   * Demonstrate

Each group will research a short list of audio effects. Each group will give a presentaion to the class about their research. The presentation should explain how each effect works, what aspects of the audio signal it is affecting ( time, frequency, amplitude ) and show examples of the effect in action. The best way to learn about the effect is to play with it. Start with the presets and then try to make some of your own settings. All of the effects on each list are related in some way. The presentations should be about 10 min in length.
