Mac's Garageband
Garageband is a great resource for student created musical compositions, as well as podcasting (more info about podcasting to follow).

Video Tutorials can be found on the Apple Website at http://help.apple.com/garageband/interface/index.html#button-1


Alternative to Garageband:
Aviary (www.Aviary.com) has an audio creation/editing tool called Myna that is free and looks like a solid alternative with most of the same functionality as Garageband. http://www.aviary.com/tools/audio-editor There is a demo video on the site as well.

At the bottom of their FAQs (www.aviary.com/faq), they mention a beta-test of "a special program for students and educators that lets them use Aviary in a completely private setting apart from the rest of the community." There is a link to contact them with your intended usage to seeing if you qualify.

This is a new website I am checking out for a variety of their media tools. If you have any experiences or successes, please share. :)
