An online mic test is a browser-based tool that uses the Web Audio API to access your device's microphone and measure its input signal in real time. Unlike system settings checks, an online microphone tester gives you visual confirmation: waveform, decibel levels, and live feedback: that your mic is actually working.
Common causes include: browser permissions blocked, wrong input device selected, outdated audio drivers, a muted mic in OS settings, faulty USB or 3.5mm connection, or hardware failure.
Before any video call, verify your microphone is picking up audio at the right volume (ideally -12dB to -6dB peak).
