Noise Gate Tool
Work out noise gate settings — threshold, attack, hold, and release — for a voice recording, without chopping the ends off words.

Suggested settings
Noise floor -52 dB, speech -18 dB: threshold -40 dB, attack 5 ms, hold 120 ms, release 250 ms — enough headroom to pass quiet consonants.
How the Noise Gate Tool works
- Measure the noise floor during silence and the speech level during normal talking.
- Set the threshold above the noise but well below the quietest speech — the gap between them is your working room.
- Lengthen hold and release until word endings stop being clipped, which is the usual complaint after gating.
The method
A gate passes audio above a threshold and attenuates below it. The timing controls decide how quickly it opens and how long it stays open after the signal drops.
threshold sits between the noise floor and the quietest wanted signal; hold and release prevent chatter
With a noise floor at -52 and speech at -18, a threshold near -40 has 12 dB of margin above the noise and 22 dB below the speech.
FAQ
Why does gating cut off the ends of words?
Because release is too short. Trailing consonants and breath tails fall below the threshold before the phrase is really over. Lengthen hold and release rather than lowering the threshold.
What is chatter?
The gate opening and closing rapidly when the signal hovers around the threshold. Hysteresis — a lower close threshold than open threshold — and a longer hold both fix it.
Is a gate better than noise reduction?
They solve different problems. A gate silences the gaps and does nothing during speech; noise reduction removes noise throughout but can introduce artefacts. For a room hum under a voice, doing both gently beats either aggressively.

Noise Gate Tool sets the threshold from your measured noise floor and speech level, which is the step that prevents clipped word endings later.
