Audacity is a remarkably powerful audio editing program that runs on Windows, Mac and Linux computers. It also happens to be free. Yes, free. It’s part of a movement that’s called Open Source. Not only does it run on all 3 kinds of computers, but it looks and works the same on all 3. So, if you’d like to know more about Audacity, you’ll want to spend a bit of time with this post on the blog of my friend Some Audio Guy.
