Microphone Test
Confirm your mic is picking up sound with a live volume meter and waveform. Choose an input device and speak — if the bars move, your microphone works. Audio is analysed on your device and never recorded or uploaded.

How to use the microphone test
Press Start microphone and allow microphone access when prompted. Then talk, tap the mic, or play some audio near it. The input level bar should rise and fall with the sound, and the waveform should wiggle in time with your voice. If both stay flat while you're clearly making noise, your mic isn't being captured — check the device dropdown and the troubleshooting list below.
The meter reads a rough loudness (RMS) as a percentage, and the peak field remembers the loudest moment since you started, which is handy for checking that sudden sounds aren't clipping. Device names appear only after you grant permission once, and if you have several inputs (a headset, a webcam mic, a USB interface) you can switch between them from the dropdown.
This test never plays your microphone back through your speakers, so there's no risk of feedback squeal, and it never records — the moment you press Stop or leave the page, capture ends.
Mic not registering?
- Permission denied: click the microphone icon in the address bar, set this site to "Allow", and press Start again.
- Right device selected? Laptops often default to a low-quality built-in mic. Pick your headset or interface from the dropdown.
- Muted at the hardware level: check for a physical mute switch or a muted input in your operating system's sound settings.
- In use elsewhere: close other apps that may be holding the microphone, then retry.
