How to Record Your Audio File In addition to your PowerPoint file, each must also turn in an audio file to accompany its presentation. Because your presentation is for the public and will attempt to influence long-held attitudes and behaviors, it is important that you speak directly to your audience. Only one person from the group should submit the group's audio file as an attachment. Please submit in .wav, .mp3, .ogg, or .wmv format. Please also include a word-for-word transcript of your audio file. When recording, position the microphone to the side of your mouth, not in front of your lips, to avoid "popping" when saying words with a plosive sound (p, b, t, etc.). Make your recording in a quiet, confined place such as a bedroom or large clothes closet away from background noises such as fans or noisy vents. When recording, if you flub a word or sentence, do not stop the recording. Simply pause, say "mark tape" and try that word or sentence again, then continue on. It is not necessary to begin all over again. Later, you may edit out the flubs if you wish, but doing so is not necessary and can be enormously time consuming. Flubs will not be counted in grading. Most computers purchased today come with some type of audio recording software and a built-in microphone (although a USB headset is preferred). If you need recording software for your computer, you can download and install a free copy of Audacity, from SourceForge. Below is an instructional video on how to download, install and use the Audacity recorder. Although the video shows you how to create an .mp3, a .wav file will be easier to export and have better quality for your purposes.
