Mic Test
Watch a live input level meter to check your microphone volume and clarity before a call — audio never leaves your device.

Before a call, it’s easier to trust a meter than to trust “can you hear me?” This page reads your microphone’s input level in real time so you can see — not guess — whether you’re too quiet, too loud, or clipping, all without sending a single sample anywhere.
How to use it
- Allow microphone access when prompted.
- Pick an input device if you have more than one.
- Talk normally and watch the VU meter — it should sit comfortably in the mid-range, not pinned to the top.
- Use the playback button to hear a short local recording of yourself.
Tips & edge cases
- If the meter barely moves, check your OS input volume first — most 'broken mic' reports are a volume slider at zero, not a hardware fault.
- A meter that's constantly pinned red means you're clipping; step back from the mic or lower the input gain in your OS settings.
- Bluetooth headsets often switch to a lower-quality call profile the moment a mic is active — if voice quality drops when you unmute, that's why.
FAQ
- Is my voice recorded or uploaded?
- No audio leaves your device. Levels are read directly from the Web Audio API in your browser, and the optional playback clip stays in local memory until you close the tab.
- Why does the meter jump even when I'm not talking?
- Fans, keyboard clicks, and room echo all register. If the noise floor is high, try a wired headset or move away from fans and vents.
- Can I test two microphones at once?
- Switch the source dropdown to compare devices one at a time — browsers only expose one active input stream per test.
