- Open up Audacity. Load your audio clip.
- 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.
- Look at the bottom of Audacity. You will see how long that silence period is.
- Now select all your audio clip by clicking Control + A.
- Now go to the Analyze menu.
- Choose Silence Finder
- 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.
- Click OK
- 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.
- Now that all your silence spots are marked to break up the clips, go to File and choose Export Multiple.
- Choose the format (wav, mp3), where to save it, how to name it, and choose Split based on labels.
- Click OK.

Note: If you need to delete a label, click on the label and backspace until all the letters or numbers are erased, then click enter (while the label is still selected).
