From the site: "Audacity® is free, open source software for
recording and editing sounds. It is available for Mac OS X, Microsoft
Windows, GNU/Linux, and other operating systems." I highly
recommend Audacity for learning about how sound recording and
editing works. It is basic enough for anyone to use, and with the
many plug-ins available, powerful enough for more challenging
projects.
