Frequently asked questions
How do I test my microphone online?
Click Start Mic Test, allow access, and speak. The meter and status badge react live. Use Record 5 Seconds to hear a playback.
Is my audio recorded or uploaded anywhere?
No. Audio is processed in your browser with the Web Audio API. The 5-second recording stays in browser memory until you close or refresh the page.
Why is my microphone not working?
Usually permission is blocked, the wrong device is selected, the mic is muted in system settings, or another app is using it. See the quick fixes above.
What does PERFECT mean?
Your voice is loud enough to be clear but not distorted. TOO SILENT means turn up your input or move closer; TOO LOUD means turn it down or move back.
Does MicTest work on phones?
Yes, on modern mobile browsers over HTTPS. Allow microphone access when prompted.
