Frequently asked questions
How do I know if my mic is working?
Start the test and speak normally. If the bar moves and the status changes to sound detected, the browser is receiving audio from your microphone. If the bar stays empty, check the device list, any hardware mute switch and your system input volume.
Why is my microphone not detected?
The most common causes are blocked permission, the wrong input selected, another app holding the device, or a disconnected cable. Allow the microphone from the address bar, close apps like Zoom, Teams or Discord, and make sure the mic is enabled in your system sound settings.
What is a good microphone level?
Normal speech usually lands between about -30 and -12 dBFS on this meter. Around -40 dB or lower sounds quiet, and anything that touches 0 dB can clip and distort, so lower the input gain if your peaks hit the end of the bar.
Is this mic test private?
Yes. The audio is analysed and recorded locally in your browser with the Web Audio and MediaRecorder APIs. Nothing is sent to a server, and the recording disappears when you close or reload the page.
How do I allow microphone access in Chrome?
Click the icon at the left of the address bar, open site settings and set Microphone to Allow, then reload the page. On macOS you may also need to allow the browser under System Settings, Privacy and Security, Microphone.
