What is the Microphone Test?
A microphone that seems fine can still be too quiet, too loud or picking up the wrong device. This microphone test shows your voice as a live waveform and a decibel level meter with a peak-hold marker, so you can see instantly whether the mic is working and how strong the signal is.
Switch between microphones, turn echo cancellation, noise suppression and automatic gain on or off to hear how they change the sound, and record a five-second clip that plays back immediately. Audio is analysed in your browser only — nothing is uploaded — and the microphone stops as soon as you press Stop or leave the page.

Questions people ask
Why is my microphone not working?
Usually the browser permission is blocked, the wrong input device is selected, or the mic is muted in system settings. The messages on this page point to the cause.
What is a good microphone level?
Speech should peak between about −18 dB and −6 dB. Constant 0 dB means clipping; below −40 dB is too quiet.
Is my voice recorded or sent anywhere?
No. Analysis and the 5-second test recording happen in your browser and are discarded when you leave.
What do echo cancellation and noise suppression do?
Echo cancellation removes speaker sound picked up by the mic; noise suppression reduces background noise. Both help calls but can colour music and singing.
Does it work with Bluetooth headsets?
Yes, but Bluetooth headsets often drop to a lower-quality microphone mode when the mic is active.
