[Are we ready then? Right here goes] Audacity is a very useful program for working with sound. With it, you can record, edit and mix sound to produce a professional sounding recording. [Oh no...Can someone get that phone please!] It's very easy to use, and the basics can be learned in a few minutes. There are some sophisticated features for people who want to [er...where am I ] do more advanced work. [Second sentence repeated] Typical uses for Audacity might be to record a narration for a PowerPoint presentation to mix music files so they seamlessly blend into one other, or to correct problems with existing recordings by using the editing and processing tools. [There's a few problems in this one that'll need sorting out!] The best thing about Audacity is that it's Open Source software. This means it can be downloaded and installed on any computer for free. There are versions for Windows, Mac OS and Linux. The software is available to download at sourceforge.audacity.net. An extra piece of software called LAME [LAME? Are you sure about that?!] is required if you want to work with MP3 files. So what are you waiting for? Download it now!
