OBS Noise Gate Settings From Your Real Mic
Measures your background noise, your quiet voice and your keyboard, then gives you OBS Noise Gate close and open values in OBS's own units. If a gate won't work for your setup, it says so. About 25 seconds. Nothing is uploaded.
Your browser will ask for mic access. Browser processing (auto gain, echo cancellation, noise suppression) is turned off for the test, so it can't change your system mic volume.
Say something · 5 s quiet · read a line · quiet voice · typing · your settings.
Esc stops the test. Levels are dBFS: 0 is the loudest your mic can record. OBS wants your voice between −20 and −9.
About these settings
How it works
- Start and allow mic access. Use the mic and input level you use in OBS.
- Stay quiet, read the line at streaming volume, then say it quietly. The quiet step sets the open threshold.
- Type for a few seconds if your keyboard is a problem.
- In OBS: right-click the mic source → Filters → + → Noise Gate. Put it first in the list and paste the values.
What the numbers mean
- Close threshold: 3 dB above the peaks of your background noise. Below it, the gate shuts.
- Open threshold: 3 dB below the peaks of your quiet speech, so soft words get through.
- Attack, hold, release: OBS defaults (25, 200, 150 ms). Lengthen the hold if the gate chatters between words.
- No numbers: your quiet voice is less than 5 dB above the noise, or your keyboard is as loud as your quiet voice. Use OBS's Noise Suppression filter or push-to-talk instead.
Why the values match OBS
OBS's Noise Gate compares the sample peak of your mic source in dBFS against its thresholds. This page measures the same signal with browser processing off, so the units match. A Gain filter above the gate shifts both thresholds by the same amount.
