FAQ
Common questions and answers about this topic.
Is my camera or microphone uploaded anywhere?
No. The preview and audio level calculation run locally in your browser. The tool does not record, upload, or save any camera or microphone data.
Why do I need to allow browser permission?
Browsers protect camera and microphone access. The test can only show a live preview or read audio levels after you explicitly allow access for this page.
Why is the device list empty or unnamed?
Some browsers hide device labels until permission is granted. If the list is empty, connect the device, close other apps that may use it, then start the test again.
What should I do if the microphone level stays at zero?
Check that the correct microphone is selected, the system input volume is not muted, and another app is not using the microphone. Then speak near the microphone and watch the live meter again.
