We need a software program for recording sounds. Let's download the software program Audacity. It is a free open source program for recording and editing sounds.
If you already have Audacity installed (some teachers might have it installed on their school computers), then you can skip the first two steps.
1. Go to the website http://audacity.sourceforge.net/.
2. If you are running Windows, click on the Download Audacity link. This will have numbers next to it for the latest version; at the time of writing (March 2012) this was version 2.0. If you have a Mac, click on Other downloads.
3. Follow the instructions on the next screen; the download will start automatically.
4. When the download has finished, go back to the website, http://audacity.sourceforge.net/download/windows.
5. Click on the Lame MP3 encoder link, and follow the instructions on the next screen.
