- Select the entire recording
- Click Effect > Truncate Silence
- The settings Min Duration, Max Duration, and Silence Threshold are used in Audacity are to determine which parts of the recording count as “silence”
- The Silence Compression module determines how much of the silence is removed in your clip. Instead of removing all silence, it simply compresses the audio.
- Finally, click OK.

How to generate sound effects in Audacity
No need to worry if you don’t have any sound effects, as Audacity has plenty of samples for you to use. The generate menu has multiple options but is not too useful on their own.
