Audio Silence Remover

Cut dead air, long pauses and silent gaps from any recording — automatically and free.

Detection settings

Anything quieter than this is treated as silence. Lower = stricter.

Pauses shorter than this stay in. Use 0.5 s to keep natural breaths.

About the silence remover

Long silences are the easiest way to lose a listener. This tool scans your audio for any stretch quieter than a threshold you set, and trims it out. It's ideal for voice memos with awkward pauses, raw interview tracks, lecture recordings, or anything where the person on the mic forgot to keep talking.

Adjust the threshold and the minimum silence length to get tight speech without chopping into actual words.

Silence remover FAQ

What threshold should I pick?

Most home recordings sit around -50 to -60 dB when silent and -20 dB when the speaker is talking. -40 dB is a safe middle. If you hear words being cut, raise the threshold; if silences sneak through, lower it.

Will it cut breaths and pauses inside sentences?

Only if they're longer than the minimum silence length you set. A 0.5 s minimum keeps natural breaths in; a 0.2 s minimum makes the result tighter and more energetic.

Is the audio re-encoded?

Yes — silence removal requires re-encoding. The output uses the same format as the input at a sensible quality default.

Does it work on music?

It's tuned for speech. On music it can clip soft passages, so use a low threshold like -55 dB or stick to the trimmer if you only need to crop the start and end.
