How to use the Microphone Test
- Click Test my microphone and choose Allow when your browser asks.
- Speak or clap. The level meter and waveform should move. Green means a good level, red means too loud.
- If you have more than one microphone, pick it from the list.
- Click Record 5 seconds and play it back to hear the quality.
Microphone not working?
- Permission blocked: click the lock or camera icon in the address bar and allow the microphone, then reload.
- Wrong device: choose the right microphone in the list above, and in your system sound settings.
- Muted: check for a mute switch on the headset or cable, and the input volume in Windows Sound settings or macOS System Settings → Sound → Input.
- In use elsewhere: close Zoom, Teams, Discord or other apps that might be holding the mic.
- Privacy settings: on Windows, go to Settings → Privacy & security → Microphone and allow desktop apps and your browser.
What's a good level?
Normal speech should land around -30 to -10 dB on the meter, in the green. Below -45 dB is very quiet: move closer or raise the input volume. Above -6 dB risks clipping, where loud sounds get cut off and distorted.
Your privacy
The sound is analysed in your browser to draw the meter. Nothing is recorded unless you press Record, and that clip stays in your browser's memory only until you leave the page. Nothing is ever uploaded.
Frequently asked questions
Is it safe to allow microphone access?
Yes. The page only listens while the test is running and processes audio on your device. Click <b>Stop</b> to release the mic, or close the tab.
Why do I hear an echo or my voice sounds different?
Turn <b>Echo cancellation & noise suppression</b> on to hear the processed sound most video-call apps use, or off to hear the raw microphone.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and Firefox. The page must be allowed to use the microphone.
Why does the meter not move at all?
The mic may be muted, the wrong device may be selected, or another app is using it. See the checklist above.
