Why it is different
Why this mic test is better
Most microphone testers only wiggle a bar. This one gives you real numbers, lets you hear yourself, and helps you fix problems.
Wave and spectrum views
Watch your voice as a live waveform or frequency spectrum, with your main pitch shown in hertz.
Record and play back
Record a 10-second clip, listen to how you really sound and download it to share with support.
Switch devices and processing
Pick any connected microphone and turn noise suppression, echo cancellation and auto gain on or off.
Left and right speaker test
Play a short tone in each ear to check your headphones or speakers are wired the right way round.
Completely private
Audio is analysed in your browser and never sent anywhere. Recordings stay on your device until you close the page.
How to use
How to test your microphone online
It takes less than a minute.
Start the test
Press the green microphone button and choose Allow when your browser asks for microphone access.
Speak normally
Talk at your usual volume. The meter should move and the badge will say your microphone is working.
Check the level
Aim for peaks between about -20 and -6 dB while speaking. Lower is too quiet, higher may distort.
Record and listen
Record a short clip and play it back to hear your real sound quality, background noise and echo.
Levels
What your microphone level means
The meter shows level in dBFS, where 0 dB is the loudest possible signal. Values are approximate and depend on your device and settings.
| Level | What it means | What to do |
|---|---|---|
| Below -50 dB | Silence or a very quiet room | If you are speaking, the mic may be muted or the wrong device |
| -50 to -30 dB | Quiet voice or distant microphone | Move closer or raise the input volume |
| -30 to -12 dB | Normal speech | Good for calls and meetings |
| -12 to -3 dB | Loud, clear voice | Ideal peak range for recording |
| Above -3 dB | Very loud, close to clipping | Lower the input volume to avoid distortion |

FAQ
Mic test FAQs
How do I know if my microphone is working?
Press the microphone button, allow access and speak. If the level meter moves and the badge says your microphone is working, it is picking up sound. Record a clip to check the quality.
Is this mic test safe and private?
Yes. Your audio is processed only in your browser. Nothing is uploaded or saved on a server, and the microphone turns off as soon as you stop the test or close the page.
Why does the meter not move when I talk?
The wrong microphone may be selected, the mic may be muted, or the browser may not have permission. Choose another device in the list and check the troubleshooting steps above for your system.
What is a good microphone level?
For speech, peaks between about -20 and -6 dB are ideal. Peaks near 0 dB can distort, and levels below -40 dB usually sound too quiet.
Should noise suppression be on or off?
Keep it on for calls in noisy rooms. Turn it off when recording music or when you want to hear the raw sound of your microphone.
Can I test my headset or Bluetooth microphone?
Yes. Connect the headset, press start and pick it from the Microphone list. Bluetooth headsets may switch to a lower-quality call mode while the mic is active, which is normal.
Does the mic test work on phones?
Yes. It works in modern browsers on Android and iPhone. Allow microphone access when asked, and use the speaker test with headphones plugged in.
Why does my recording sound different from the live meter?
The recording includes the processing you chose, such as noise suppression and auto gain. Try turning them off and recording again to compare.
