Recording Audio Presentations for Posting Online

You have many options when it comes to recording audio for posting online. You will need software that can record audio to accomplish this. You can use any software you want (such as RecorderPro for Windows or GarageBand for the Mac) as long as the software can make an MP3 file of your final recording. This tutorial covers recording audio using a program called Audacity® — a simple, free program for recording and editing audio.

To begin, you should have a USB headset microphone. A USB connection looks like this:


The Center for Teaching and Learning with Technology only offers technical support for USB headset microphones. Analog microphones and built-in microphones on laptops are not supported.

Because Audacity is a free application, not everything you need is included in a single download. You must first download and install Audacity, and then install a piece of software called LAME that will let Audacity create MP3 files.

Download and view the Guide to Using Audacity from the link below for detailed instructions which includes screenshots and demos all in one document.
