Test Your Microphone Instantly — No Download Needed
Check whether your microphone works before a call, game, stream, or recording. Choose the input you actually want, watch the live level respond, then record a six-second sample and play it back in your browser. The meter confirms that a signal is arriving; playback helps you hear noise, muffling, distortion, or the wrong microphone. Nothing is uploaded, and you do not need an account or download.
Microphone Not Working? Check These Four Things
First check the browser permission, then make sure this page is using the input you want. If the meter barely moves, unmute the mic, move closer, or raise the input level in your system settings. If the peak stays near 0 dBFS, lower the input level. If the sample sounds right here but not in Discord, Zoom, or Teams, choose the same input inside that app and run its own microphone test.
