Apply a Noise Gate to Audio
A noise gate mutes the recording whenever the speaker isn't talking, removing room tone and bleed in the gaps. It's the classic first step for a clean, punchy voice track.
How it works
We track the short-time level of the audio and compare it to an adaptive threshold. When the level falls below it — between phrases — the gate attenuates the signal; when speech returns, it opens smoothly.

Frequently asked questions
A gate removes noise only in the silences between speech; a denoiser removes noise underneath the speech too. For the best result, denoise first, then gate the gaps.
The threshold adapts to your recording and the open/close is smoothed, so natural word tails pass. Very quiet speech may need a lower threshold.
No — it processes the whole file offline with smoothed transitions, so there's no live-monitoring latency and no chattering.
Yes. The threshold adapts by default, and you can set it manually if your noise floor is unusually high or low.
Yes. Gating is standard on drums and amps to cut bleed in the gaps, and the same level-based gate applies to any source.
No. A noise gate is a lightweight DSP operation that runs instantly without a GPU.
No. It reacts to signal level rather than words, so it works on speech in any language and on non-speech audio alike.
