Mic Test
Check your microphone with a live waveform, level meter and instant playback.
Everything runs locally in your browser. Nothing you do here — audio, video or input — ever leaves your device.
Click the button below and your browser will ask permission to use the microphone. The audio is analyzed locally on this page — nothing is recorded on a server or uploaded anywhere.

How it works
When you start the test, the page requests microphone access through your browser's standard permission prompt — audio only flows after you approve, and it flows only into this page. The stream feeds a Web Audio analyser that draws the live waveform and computes your input level in decibels. Speak normally: a healthy setup shows a clearly moving waveform and peaks around −12dB. A flat line means the wrong device is selected or the input level is muted in your OS.
The record-and-playback loop captures five seconds into your browser's memory and plays it straight back, so you can judge clarity, noise and echo exactly as others would hear you on a call. The clip is held in memory only — closing the page destroys it. Use the device picker to test every microphone connected to your machine, and check the reported sample rate matches what your recording software expects. If your mic doesn't appear at all, our mic troubleshooting checklist covers Windows 11 and macOS privacy settings step by step.
Troubleshooting
› The browser says microphone access is blocked
Click the camera/mic icon in the address bar and allow access, then reload. On Windows also check Settings → Privacy → Microphone; on macOS check System Settings → Privacy & Security → Microphone.
› The meter barely moves when I speak
Select the right device in the input picker — many laptops expose several inputs. Then raise the input level in your OS sound settings and make sure the mic isn’t hardware-muted.
› I hear an echo during playback
Playback replays the clip you just recorded, so hearing yourself is expected. Echo during live monitoring means your speakers are feeding back into the mic — use headphones.
Frequently asked questions
› Is my voice recorded or uploaded?
Never. Audio is analyzed live in your browser; the optional playback clip lives only in memory and is gone when you leave the page.
› Why does the site ask for microphone permission?
Browsers require your explicit consent before any page can access a microphone. The prompt comes from your browser and applies only to this test.
› What does the dB level mean?
It shows your peak input level. Around -12dB while speaking normally is healthy; constantly hitting 0dB means clipping (too loud), and below -40dB is too quiet.
› Can I test multiple microphones?
Yes — use the device picker to switch between any connected inputs without reloading.
