Silence remover
Long pauses wear listeners out and make files longer than they need to be. The tool finds the gaps below the threshold you set, marks them on the waveform, and removes them when you confirm.

How to use
- Choose the recordingDrop your lecture, podcast, interview or meeting recording.
- Check the settingsThe parts to be removed are hatched on the waveform. As you change the threshold, minimum silence and padding, the marks update instantly.
- Remove and downloadPress "Remove silences", listen to the shorter recording and download it.
What the settings do
| Setting | Meaning | Suggested start |
|---|---|---|
| Silence threshold | Sound below this level counts as silence. | -40 dB; -35 dB for recordings with hum |
| Minimum silence | Pauses shorter than this are left alone, so speech keeps its natural rhythm. | 0.5 s; 0.8 s for presentations |
| Padding to keep | A short silence left on both sides of each cut, so words don't run together. | 0.1 s |
Where it helps
- Lectures and training recordings: Drop the gaps while writing on the board or changing slides.
- Podcasts and interviews: Shorten the thinking pauses so the recording flows better.
- Before transcription: A shorter recording is quicker to listen to and check against the text.
- Voice messages and notes: Tighten recordings full of long pauses.
If there's constant hum, music or air conditioning in the background, the "silent" parts may stay above the threshold. Try noise reduction first, or raise the threshold.
Privacy: your recording never leaves your device
Everything happens in your browser. Your file is not sent to Voiser's servers or stored anywhere, and it's cleared from memory when you close the tab. That's also why the tool stays fast on a slow connection.
Common questions
Will part of the speech be removed too?
No, every sound above the threshold is kept. If someone speaks very quietly and falls below the threshold, lower it (for example to -50 dB); you see the parts to be removed on the waveform beforehand.
I don't want the pauses gone completely. What should I do?
Increase "Padding to keep" (for example to 0.25 s). Long silences are removed, but a short, natural breath is left at each cut.
How much time will I save?
The tool tells you before processing: the number of silent parts, the time saved and the new duration appear under the waveform.
Can I use it on music?
It's designed for speech. Quiet passages in music are part of the composition; to trim silence at the start and end of a track, the MP3 cutter is a better fit.
