Introduction
Audacity is a free digital audio editor and recording application that runs on Mac or PC. For this workshop, we will be using version 2.0.4 for Mac which can be downloaded here: http://audacity.sourceforge.net/
Set Sample and Bit Rates
1) Click on Audacity in the upper lefthand corner, then select Preferences.
2) In the dropdown menu, go to Quality.
3) Here you can select your “Sample Rate” (measured in Hz) and your “Sample Bit Format” (resolution). In addition to quality and resolution, these settings also affect file size.
If you are going to stream your audio as a podcast or burn to CD, use these settings:
- Sample Rate: 44100 Hz
- Sample Format: 16-bit
If you plan to import your audio into a video project, use these settings:
- Sample Rate: 48000 Hz
- Sample Format: 32-bit
Importing Audio Files
Formats that can be imported: WAV, AIFF, AU, MP2/MP3 or OGG Vorbis
1) When you open the application, it will immediately open a new project screen.
2) Select “Save Project As” to name your project and save a copy to the desktop. Audacity will save it as an “.aup” file (we will export to other formats later).
3) To import the sample audio files, go to File > Import Audio
4) Select the “Audacity Sample Files” folder from your desktop. You can select all four (4) files at once by holding down the COMMAND key.
5) When they are finished importing, you should have a project screen that looks like this:
6) You can listen to each individual track by clicking the Solo button, then hitting Play.
7) If one track is too loud or soft, you can adjust its master volume by sliding the fader.

Envelope Tool
The envelope tool is useful for ramping audio levels. Selecting the tool will add blue volume bars onto the timeline.
1) Activate the library music track “Lib_ICMRS” by hitting solo.
2) Select the Envelope tool; you should see the blue lines appear.
3) Click around :06 to make your first point, then another around :08. You can control these levels by sliding the points up and down. Audacity will create a path between these points to make a smooth volume adjustment, or in this case, a fade out.
4) If you accidentally add too many control points, click on the point you want to delete, drag it outside of the track, then let it go.
Fade Effects
1) For fading in and out of tracks, you can also use effects.
