Audio Silence Remover
Automatically cut quiet/silent stretches out of an audio file.
About this tool
Automatically cuts out quiet/silent stretches from an audio file — dead air between sentences, long pauses, background hiss during a break — leaving the spoken/audible parts stitched back together. A small amount of padding is kept around each cut so words aren't clipped. Everything runs locally in your browser; nothing is uploaded anywhere.
Useful for tightening up a podcast recording, voice memo, or interview before publishing, without manually scrubbing through the whole file.
Frequently asked questions
- What do the two sliders control?
- "Silence threshold" is how quiet a moment has to be to count as silence — lower (more negative) is stricter, only counting truly silent audio; higher picks up more of your recording's quiet background noise as "silence" too. "Minimum silence length" is how long a quiet stretch has to last before it gets cut — short natural pauses between words are kept even at a low setting, since only stretches longer than this are removed.
- Will this ever cut off the start or end of a word?
- A small padding window is kept on both sides of every cut specifically to avoid this, but on very abrupt speech or an overly aggressive threshold, an occasional word edge can still get clipped — if that happens, try a lower minimum silence length or a stricter (more negative) threshold.
- Is my audio uploaded anywhere?
- No — decoding, analysis, and encoding all happen entirely on your device.
