Stumbled on this by chance:

At http://www.giveawayoftheday.com/, you can, for the next 12 hours, get a pretty good audio editing program.
It MUST be both downloaded, and installed and registered withing the time limit.

If you decide to get it, read the instruction carefully, including part about filling in all blanks in form and using the provided registration key.
