The purpose of this exercise is to give you the opportunity to edit a voice recording in Audacity. The key to editing this recording is to be aware of both the sound AND the silence as you edit.


  1. Download this file into your folder - in the lab, right-click the link and choose Download Linked File As, navigate to your folder and save the file there. Then, double-click the zip file to uncompress it and extract its contents. If you download the above zip file into the Downloads folder, move it to your folder before extracting it.
  2. After extracting the file you should find a file called "count.mp3" in your folder.
  3. Open the file in Audacity and listen to it. You'll hear it's a recording of JM counting from 1 to 10.
  4. Edit the recording, rearranging the numbers (e.g. 1, 6, 4, 2, 7, etc.) while maintaining the rhythm and cadence of the original. (It's very important that you keep the rhythm and cadence the same.)
  5. When done, export MP3 versions of the modified recording in both 128 kbps and 64 kbps bit rates.
    1. Choose Export from the File menu.
    2. Set the format to MP3.
    3. Click the Options buttons and change the bitrate to the desired rate. We will demonstrate how to choose the 64 kbps option in class.
    4. Make sure you export these files to your folder and be careful not to overwrite the first recording when saving the second. (Suggestion: add 128 to the name of the 128 kbps file; 64 to the name of the 64kbps file.)
  6. Email the 64 kbps version to JM at the assignments address listed in the syllabus.
