How to Use Audacity to Break Audio Clips Up and Export as Separate Files

Audacity-logo-r_50pct.jpg

Did you ever have a long audio clip that you wanted to break up into
smaller files based off of pauses or silence breaks in your audio? Sure
you can do it manually with a program like Audacity, but Audacity also
has a Silence Analyzer that will insert labels in places where there is
silence in the clip and from those tags you can export the audio into
smaller chunks all in one step. Here’s how to do that.

  1. Open up Audacity. Load your audio clip.
  2. Now use the cursor to scroll over the shortest silence period in
    your clip. This is where a label will be inserted to show a break in
    audio parts. You are measuring the time.
  3. Look at the bottom of Audacity. You will see how long that silence period is.
  4. Now select all your audio clip by clicking Control  + A.
  5. Now go to the Analyze menu.
  6. Choose  Silence Finder
  7. In the minimum silence duration text box, type in the number you
    saw at the bottom of Audacity when you measured the shortest silence
    period in the clip.
  8. Click OK
  9. Now you will see a series of labels with a S. You can also manually
    enter labels (if the analyzer missed any spots) by clicking on the
    silence spot and pressing Control + B.
  10. Now that all your silence spots are marked to break up the clips, go to File  and choose Export Multiple.
  11. Choose the format (wav, mp3), where to save it, how to name it, and choose Split based on labels.
  12. Click OK.
