How to use the microphone test
- Tap Start microphone test and allow microphone access when your browser asks.
- Speak normally, at the volume you'd use on a call, and watch the meter move.
- If you have more than one microphone, use the dropdown that appears to switch between them.
- Watch for the meter sitting comfortably in the green to amber range; frequent spikes into red mean your input is too hot.
- Tap Stop to end the test and release the microphone.
What this test checks
- Microphone detection: confirms your operating system and browser can see the microphone at all.
- Permission handling: confirms a site or app will be able to request access without hitting a blocked setting.
- Input level: shows whether your normal speaking voice registers clearly without being too quiet or clipping too loud.
- Background noise: a meter that never sits near zero even in a quiet room may point to a noisy or faulty input.
Who this is for
- Before a video callConfirm your mic works and your input level is reasonable before joining a meeting.
- Podcasters and streamersCheck a new microphone or audio interface is actually being picked up correctly.
- Remote job interview candidatesTest audio on an unfamiliar device or borrowed headset ahead of time.
- IT support and helpdesk staffQuickly tell apart a hardware fault from a muted or misconfigured input.
- Voiceover and content recordingSpot-check gain levels before a recording session.
- Buying a used headset or webcam micConfirm the microphone actually works before you commit to the purchase.
Frequently asked questions
Does this tool record or save my audio?
No. Your microphone is analyzed live to drive the meter and nothing else. No audio is recorded, stored, or sent to any server, and the input stops the moment you tap Stop or leave the page.
The meter isn't moving at all. What's wrong?
Start by checking your browser's site permissions to confirm microphone access is allowed for this page. If it is, check that the correct microphone is selected in the dropdown, and that it isn't muted at the hardware level, such as a physical mute switch on a headset.
What's the difference between this and my system's input volume setting?
Your operating system's input volume controls how sensitive the microphone is before any app sees the signal. This meter shows what actually comes through after that setting is applied, which is closer to what a call or recording app will actually receive.
Can I test an external USB microphone or headset?
Yes. Plug it in before starting the test, and it should appear as an option in the microphone dropdown once you grant permission, alongside any built-in microphone.
Does this test cancel or measure background noise separately?
No, it shows raw input level only. To judge background noise, stay silent for a few seconds after starting the test; if the meter still shows meaningful movement with nobody speaking, that's ambient noise your microphone is picking up.
Why does the meter jump around so much even when I'm not talking loudly?
Microphones respond to sudden sounds like keyboard clicks, breathing, or a nearby fan, not just speech, so some movement between words is normal. Consistent spikes into the red zone during normal speech, though, usually mean the input gain is set too high.
