Check a phone microphone with a live sound meter and local voice recording and playback.
Allow microphone access when you start. Speak normally and watch the sound meter. Record a short phrase and play it back to check clarity. Disconnect headsets first.
A moving meter proves sound reached the browser, not clear speech or that every microphone works. Playback needs your listening confirmation.
Microphone permission is requested after you start. The test recording stays on this device.
Results are saved only in this browser for up to 24 hours. This single test does not replace a complete used-phone inspection.
