Creating Sound Files with Audacity
Audacity is a free, easy-to-use audio editor and recorder for
Windows, Mac OS X, GNU/Linux, and other operating systems.
You can use Audacity to:
    Record live audio.
    Edit MP3 and WAV sound files.
    Export MP3s with the optional LAME encoder library.
    Edit easily with Cut, Copy, Paste, and Delete.

Marshaʼs enhanced podcast describes how language teachers can import a student recording, record
comments and corrections, export the file as an mp3, and teach listeners to hear one or both tracks. (Itʼs called
an *enhanced* podcast because it integrates photos with audio, all of which can be loaded onto and played on
an iPod. Done in Audacity, GarageBand, and other tools) http://www.ourmedia.org/node/166635
