What mictest.wiki is

mictest.wiki is a single-purpose tool: confirm whether your microphone works, in your browser, in a few seconds. No account, no install, no upload.

The test runs entirely on the standard getUserMedia and Web Audio API built into every modern browser. Volume, frequency, and the waveform you see are computed locally on your device — nothing is sent to a server, and the optional 5-second recording never leaves your browser tab.

The guides section exists because a mic test alone doesn't fix anything — it tells you something is wrong. The guides are written from actual troubleshooting order of likelihood, not padded to hit a word count.

The site was rebuilt in 2026 as a static application with no database and no admin panel exposed to the internet, prioritizing speed and security over anything else.
