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.

I hope this helps. It worked well for me.
