Why test your microphone before a call?
A muted mic is the single most common reason people lose the first two minutes of a meeting. A quick test takes five seconds and saves the awkward "you're on mute" moment. It also catches the trickier problems: a Bluetooth headset that paired but did not switch its microphone, a USB mic stuck on the wrong sample rate, or a browser that quietly defaults to a different input.
What the input meter actually shows
The bars react to the loudness of what your mic is picking up right now, measured as a root mean square value. Talking at a normal volume should push the meter into the green and orange range. If your voice never moves the meter, the browser is not getting audio. If even silence pushes the meter near the top, your input gain is too high and you should lower it in your system sound settings to avoid clipping during the call.
The microphone access is handled by the browser's getUserMedia API, a web standard maintained by the W3C. The audio is analysed entirely in your tab using the Web Audio API.
Common problems and what fixes them
"The meter never moves"
Open your operating system sound settings and confirm the right device is set as the default input. On Windows, check Settings, System, Sound. On macOS, open System Settings, Sound, Input. Then refresh this page so the browser picks up the new default.
"Permission was blocked"
Click the lock or camera icon in your browser's address bar, change microphone access to Allow, and reload. In Chrome you can also go to Settings, Privacy and security, Site settings, Microphone.
"My Bluetooth headset sounds awful"
Most Bluetooth headsets drop to a low quality call profile (HFP or HSP) the moment any app opens the microphone. Music sounds great, the mic sounds tinny. For important calls a wired headset or a USB mic gives a much cleaner result.
"People say I echo"
Echo happens when your speakers play the other person's voice and your mic picks it up. Wear headphones, lower the speaker volume, or move the mic further from the speakers.
Privacy first, by design
We do not record or store anything. The audio stream is analysed in your browser and discarded frame by frame. There is no server upload because there is no server in this loop. You can read more in our privacy policy. This approach follows the principle of data minimisation laid out by the GDPR.
Frequently asked questions
How does this microphone test work?
Your browser asks for permission to use the mic, then we read the audio stream with the Web Audio API and show the loudness as a live meter. The audio never leaves your device.
Why is the meter flat when I speak?
The browser may be using a different input device, your system mic may be muted, or another app like Zoom or Teams is holding the mic. Close other apps, pick the right input in system settings, and retry.
Does this work on iPhone and Android?
Yes. Open this page in Safari on iOS or Chrome on Android and allow microphone access when prompted.
Can I test a USB or Bluetooth mic?
Yes. Connect it first, set it as the default input in your operating system, then refresh this page and click Test Microphone.
Your audio never leaves your device
Stop the test whenever you want. The mic indicator in your browser disappears the moment you release the device.
