Mic Test
Test your microphone in seconds: live input level, waveform, record-and-playback, device and sample-rate details, plus fixes if it isn't working. Nothing is recorded or uploaded.
How it works
- 1
Start the test
Press Start and allow microphone access when your browser asks.
- 2
Speak and watch the meter
The level meter and waveform react as you talk, and the status turns green when sound comes through.
- 3
Record a playback
Record a few seconds and listen back to hear what others hear on a call.
- 4
Fix any issues
If nothing registers, switch the input device or follow the troubleshooting tips shown.
Common uses
- Check your microphone before a Zoom, Teams or Google Meet call.
- Compare two headsets or USB mics by recording and playing back a clip.
- Work out whether a 'no sound' problem is the mic, the browser or the call app.
About the Mic Test
Test your microphone in seconds: live input level, waveform, record-and-playback, device and sample-rate details, plus fixes if it isn't working. Nothing is recorded or uploaded.
The meter measures your signal in real time with the Web Audio API and shows it in decibels relative to full scale (dBFS), so you can see whether you're too quiet, clipping or silent. The stream never leaves the page, and recordings exist only in memory until you close the tab.
Mic Test is part of a free, privacy-first toolkit. It uses your browser's built-in device APIs, so it starts instantly with nothing to install — and nothing you type, say or show ever leaves your device.
Because mic test works without any sign-up or installation, you can use it as often as you like and it's always available — on desktop or mobile, and even offline.

Mic Test — FAQ
Start the test and speak. If the level meter moves and the status turns green, your microphone is picking up sound. Record a short clip and play it back to check it sounds clear.
