Microphone test
Check your microphone is working before a meeting.
Click Start to request microphone access. Speak normally — the bar should move with your voice. If it stays flat, check the OS mute / input source.
About this tool
Nothing kills a meeting faster than a microphone you didn't realise was muted. This test asks your browser for microphone access and shows a live input-level bar — if the bar moves when you speak, your mic is working. No audio is recorded, nothing is uploaded, and the stream closes the instant you click Stop or leave the page. If you see no signal at all, the error messages distinguish between "permission denied" and "no device found" so you know where to look next.
Frequently asked questions
Is my voice being recorded?
No. The microphone stream stays on your device and is used only to compute the real-time level shown on the bar. It's released the instant you click Stop or leave the page. No audio is uploaded anywhere.
Why does the browser ask for permission every time?
Some browsers (and some privacy settings) treat microphone access as one-session-only, so permission resets each visit. You can usually grant it permanently via the lock icon in the address bar.
The bar doesn't move even though I'm speaking. What's wrong?
Usually one of three things: the OS-level microphone is muted, a different input device (e.g. HDMI) is selected as default, or another app is holding the mic exclusively. Check your operating system's sound settings.
