Mic Test
Check that your mic works, how loud you are and how much noise it picks up. Then get OBS noise gate settings from your own voice and room. 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 · optional quiet voice and typing · results.
Esc stops the test. Levels are dBFS: 0 is the loudest your mic can record. OBS wants your voice between −20 and −9.
About this mic test
How it works
- Start and allow mic access. Pick your mic if the wrong one came up.
- Say something, stay quiet for five seconds, then read the line at your normal volume.
- Optionally say it quietly and type for a few seconds.
- Read the result, copy the OBS settings, listen to the recording. Re-test after changes.
What it checks
- Works: whether anything reaches the browser, and the likely blocker if not.
- Level: where your loud words peak against OBS's −20 to −9 dBFS band.
- Noise: your background floor and how far your voice sits above it.
- Problems: clipping, 50/60 Hz hum, audio gaps, and narrowband audio from a Bluetooth headset in call mode.
- Settings: OBS Noise Gate thresholds from your own background and quiet voice, or a clear "don't use a gate" when they overlap.
What level should my mic be?
Loud words should peak between −20 and −9 dBFS, the yellow band on OBS's meter. Lower: raise the input level or move closer. Higher: turn the gain down.
Good OBS noise gate settings
OBS defaults to close −32 dB and open −26 dB. The right values depend on your room: close just above your background noise, open just below your quietest speech. This page measures both. If they're too close together, use Noise Suppression instead.
Why does my Bluetooth headset mic sound bad?
When the mic turns on, Bluetooth headsets switch to a call profile with telephone-quality audio. Use another mic for input and keep the headset for listening.
