Help & troubleshooting
CheckMyMic's webcam and mic test checks your camera and microphone together in one pass: press Start check, allow camera and microphone access, and you get a live camera preview with resolution and FPS readouts sitting right next to a live mic level meter and an instant verdict. A brief loud mic peak is a warning; use the full microphone test to make and play back a recording after you adjust gain. Sustained clipping remains a clipping result. No download, no signup, and nothing leaves your device.
How the webcam and mic test works
We request both devices in a single getUserMedia call. Your browser controls
how many permission prompts appear. Once access is allowed, the video track drives the
live preview while the audio track feeds the same Web Audio analysis the standalone mic
test uses — measuring peak level many times a second and turning it into a plain
verdict for both devices at once. A brief loud peak is kept as an amber warning rather
than being presented as sustained clipping; use the full microphone test
to make and play back a recording after you adjust gain.
Video and audio never leave your browser. Both streams stay in memory on your device. The check stops after 10 seconds and turns both devices off. Choose Keep testing to continue until you press Stop. Switching tabs or leaving also stops capture.
When to run this check
Use it a few minutes before a Zoom, Teams or Google Meet call to confirm your setup works end to end, or right after plugging in a new headset and webcam to make sure both halves are talking to your computer. If you need a deeper look at just one device, the full microphone test adds noise and clipping detail, and the full webcam test adds camera switching and a snapshot — or run the interview-ready check to add speakers too.
Webcam & mic test FAQ
How do I test my webcam and microphone together?
Press Start check and allow camera and microphone access. The 10-second check begins once a camera frame arrives and audio processing starts. It stops both devices and retains your results, including a brief loud-peak warning when one occurs. Choose Keep testing if you need more time.
Why does the browser only ask permission once?
We request camera and microphone access in a single getUserMedia call,
but the browser controls the number and appearance of permission prompts.
Is this private?
Yes. The video preview and the mic analysis both run locally in your browser. Nothing is uploaded, recorded remotely or stored — both devices are released the moment you press Stop or leave the page.
Why is my mic bar not moving?
Check you picked the right microphone in the dropdown, that it isn't muted at the OS level, and that no other app (Zoom, Teams, Discord) is already holding it. Speak normally — the bar reacts to your voice level in real time.
Can I use this to test for Zoom or Teams?
Yes — it's a great way to confirm your camera and mic both work with your current headset and browser before you join a call. A brief loud peak is a warning, while sustained clipping is reported separately; use the full microphone test to make and play back a recording after you adjust gain. Meeting apps can use different devices and permissions, so verify their settings too; a browser result is not a guarantee.
