How to remove silence from a recording

🎙️

1. Load your audio

Drop in an MP3, WAV, M4A or any audio your browser can play. It decodes locally.

🎚️

2. Tune the detection

Set how quiet counts as silence (threshold) and how long a pause must be before it is cut.

3. Preview & export

Red regions show what will be removed. Preview the result, then export MP3 or WAV.

Long pauses make podcasts and lecture recordings feel slow — trimming them can shorten a recording by 20–40% without losing a word. The remover keeps a little padding around speech so cuts never sound abrupt, and joins every cut with a micro crossfade to avoid clicks. For manual precision cuts use the Audio Cutter, or level the volume afterwards with the Audio Normalizer.

Silence remover FAQ

How does silence detection work?

The tool measures loudness in short windows across the whole file. Stretches quieter than your threshold that last longer than the minimum duration are marked as silence and removed, with padding kept around speech so words are never clipped.

What threshold should I use?

-40 dB works for most voice recordings. If too much is being cut, lower it towards -50 dB; if breaths and room noise survive, raise it towards -30 dB. The waveform shows exactly what will be removed before you commit.

Will the cuts be audible?

No — every join uses a short crossfade, and the padding setting keeps a natural breath of air around each phrase.

Is my audio uploaded?

No. Decoding, detection and export all run inside your browser. Nothing is sent to any server.
