About Online Mic Test
Online Mic Test is a browser-based tool for checking whether a microphone is working and properly configured. Users click play, allow browser microphone access, and watch a line move when the microphone detects sound. The site says its tests run on the client side and that it does not and cannot record voice or other information. It provides troubleshooting steps and links to operating-system and program-specific microphone settings guides. If the microphone works on the site but not in another program, it directs users to that program's support.
