Microphone Test
Test your microphone online with a live level meter, waveform and spectrum view, peak dB readout, noise-suppression toggles and a 5-second record-and-playback check.

This microphone test gives you instant visual feedback: a level meter shows the average loudness (RMS) of your voice, a red marker holds the highest peak, and a live waveform or frequency spectrum shows the signal itself. Levels are shown in dBFS, where 0 dB is the loudest possible digital level. Normal speech should peak somewhere between about -18 dB and -6 dB; if the peak hits 0 dB, the sound is clipping and will be distorted.
The spectrum view is useful for spotting hum at 50 or 60 Hz, hiss across the high frequencies or a muffled microphone that lacks treble. To hear the result, record a five-second sample and play it back. You can switch between several microphones — for example a headset, a webcam mic and a USB microphone — and compare them in seconds.
Noise suppression, echo cancellation and auto gain
Browsers include the same audio processing used by video-call apps. They are switched off by default here so you hear the raw microphone. Turn on noise suppression to remove fan and keyboard noise, echo cancellation to stop your speakers leaking back into the mic, or auto gain control to level out your volume. The input panel confirms which filters the browser actually applied. Nothing is uploaded: analysis and recording happen entirely in your browser.
Troubleshooting microphone problems
If access is blocked, click the lock or microphone icon in the address bar and allow the microphone for this site. On Windows and macOS, also check the privacy settings that control which apps may use the mic. If the meter stays flat, select another input, check for a mute button on your headset and make sure the input volume in your system sound settings is not at zero. A message that the mic cannot be started usually means another application is using it exclusively.
