Toujours l'audace, et encore l'audace!

I've been playing around 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.
  
• Convert tapes and records into digital recordings or CDs.
  
• Edit Ogg Vorbis, MP3, and WAV sound files.
  
• Cut, copy, splice, and mix sounds together.
  
• Change the speed or pitch of a recording.
  
• And more! See the complete list of features.
  

Here's an excellent tutorial on Audacity from the public radio site Transom.org.
