Another extra credit option - audio editing demo

If you know the base-level audio editing programs well (Audacity / Garage Band), here is a chance to earn a few points of extra credit. A peppy, thorough and engaging 5 minute demo on either program is worth 5 extra credit points. First email I get on either claims the opportunity. I would like these to be done by two different people, unless there is only one person interested (and that person wants to do both). These demos will be part of the April 20th class. Any takers?
