Online Mic Test

Press Start mic test and allow microphone access when your browser asks. Speak normally: the meter and the signal history move with your voice, and the verdict tells you if the level is too quiet, good or too loud. Press Record to capture 10 seconds and play it back to hear exactly what others will hear.

No. The test runs entirely in your browser. Nothing is recorded unless you press Record, and that recording stays in your browser's memory for playback. It is never uploaded and disappears when you close the page.

Check that the mic is plugged in and not muted, then allow microphone access for this site in your browser (the icon to the left of the address bar). On Windows, open Settings, Privacy and security, Microphone and allow access for your browser. On a Mac, open System Settings, Privacy and Security, Microphone and turn your browser on. Close other apps that might be using the mic, then press Start again.

When you speak at a normal volume, the meter should sit in the green zone, roughly between -30 and -12 dB. Short peaks can go higher, but the level should never hit 0 dB, because that clips and distorts the sound. If it stays in the grey zone, move closer or raise the input gain.

Browsers clean up microphone audio with echo cancellation, noise suppression and automatic gain. Video calls usually keep them on. Streaming and recording apps often turn them off. Switch it off to hear your raw microphone, or on to hear what a video call would send.

Yes. It works in Safari on iPhone and iPad and in Chrome on Android. Allow microphone access when asked. Recording playback uses your phone's speaker, so use headphones to avoid feedback.
