About this tool
Cut the dead air out of a recording and keep the pauses that belong. Free and unlimited, and nothing is uploaded: it all runs in your own browser. Everything is analysed and produced on your own device — nothing is uploaded anywhere, and you can verify it: the tools keep working even offline.
Privacy & limitations
Multi-hundred-megabyte recordings can exhaust the browser's memory — everything runs on your machine, so your machine is the limit. Aggressive thresholds clip soft speech along with the silence; listen to the result before sending it anywhere.

Frequently asked questions
Will it cut into my speech?
Two settings decide that. The threshold sets how quiet counts as silence, and the minimum length stops it touching anything shorter, so natural pauses between words survive. If it is clipping soft speech, use a lower threshold such as -60dB.
What threshold should I use?
Start at -50dB, which is about a quiet room. A noisier recording, with a fan or traffic behind it, needs -40dB or higher before the noise floor counts as silence at all.
Does it work on video?
Video files are accepted and the silent stretches are removed, though be aware the picture is cut along with the sound, so anything happening on screen during a silence goes too.
Can I get the gaps back?
Not from the output. Keep the original if the recording matters; this writes a new file and leaves yours alone, so the safe move is simply not to delete it.
