How to remove silence from an audio file
- Choose an MP3, WAV, M4A, AAC or FLAC file, or drop it on the waveform.
- Check the shaded gaps. Raise if quiet room noise is left in, lower it if soft words are cut.
- Play the result and listen to the joins.
- Download the WAV and use it in your editor or podcast host.
Settings that suit common recordings
- Podcast or interview: shortest pause 600 ms, keep 150 ms around speech. Conversation keeps its rhythm.
- Voice memo or lecture: shortest pause 400 ms, keep 100 ms. Long thinking pauses go, sentences stay intact.
- Tight voice-over: shortest pause 250 ms, keep 60 ms. Every gap closes.
Silence at the start and end
Dead air before the first word and after the last is cut with the rest. If you only want those trimmed, raise to 2,000 ms so pauses inside the recording stay.
Why nothing is uploaded
Your browser decodes the file and the page measures its loudness every 10 milliseconds. The cut and the WAV are built in this tab, so a private recording stays private.
