Audio Noise Gate

Silence the background hiss between words. Adjustable threshold for speech, vocals and instruments.

Anything quieter than this is muted. -45 dB is safe for most voice recordings; lower if hiss still bleeds through.

How aggressively material below threshold is reduced. 9:1 is firm; 20:1 is essentially a hard mute.

About this noise gate

A noise gate mutes the audio whenever it falls below a threshold you set — leaving the loud parts untouched. The result is clean silence between phrases instead of a constant fan / room / hiss bed.

Different from the silence remover, which deletes the silent sections entirely. A gate keeps the timing intact and only mutes — useful when you want the gaps to stay but the noise floor to disappear.

  • Useful for podcasts, voice-overs, instrument tracks and live recordings

Noise gate FAQ

Gate vs silence remover — what's the difference?

A gate mutes the quiet sections; a silence remover deletes them. Use a gate when timing matters (talking-head video sync); use silence remover to tighten a long monologue.

What's a good threshold?

Most home recordings sit around -50 to -55 dB when silent and around -25 to -15 dB when the speaker is talking. -45 dB is safe; -40 dB is more aggressive.

Will it cut into words?

Only if the threshold is too high. If the start of words gets clipped, lower the threshold by a few dB.

Will the audio be re-encoded?

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