Remove silence. Not the words.

Cut the dead air out of an interview, a lecture or a voice note. You decide how quiet and how long a gap has to be. Nothing is guessed, and the same settings always give the same result.

Common questions

Is this AI?+

No, and that is the point. It measures the actual signal level and removes stretches quieter than the threshold you choose. It is deterministic: the same file and the same settings give the same result every time, with no outside service involved and no model guessing at your audio.

Will it cut the ends off words?+

Only if you tell it to. Start at Normal. Aggressive treats quiet breaths as silence, which is useful for a very clean recording and too eager for a soft speaker. Short gaps are never cut: you set the minimum length, so the rhythm of speech survives.

Why does it leave a small pause?+

Because cutting silence to nothing makes sentences run into each other and sounds worse than the original. By default a short pause is left where each gap was. You can turn that off if you want everything closed up.

Can I use it on a video?+

No, and we refuse rather than doing it badly. Removing the quiet stretches from a video's soundtrack without removing the same stretches from the picture pulls the two out of sync, and it gets worse the further into the file you go. Trim a video with the Trim tool instead.

What happens to my file?+

It is uploaded over TLS to our private storage (Supabase, named in our privacy policy), processed on our own engine, never by an outside service, and both the upload and the result are deleted after 1 hour.

Is there a limit?+

Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB. No signup, no watermark.
