What Mic test does
Mic test is a browser-based utility that captures audio input from a user's device to verify microphone functionality. By requesting permission to access the hardware, the tool records ambient sound and renders a real-time oscillating waveform, allowing users to visually confirm that the equipment is working and assess basic audio quality. The process requires no software installation, functioning entirely within the web page.
