How do I start the microphone test?

The test starts automatically when you load the page. Your browser will then ask for permission to access your microphone. Once you grant permission, you will see a live visualizer of your microphone's input.

Is my audio sent to your servers?

No. For your privacy, all audio processing is done locally within your web browser. Your voice data never leaves your computer.

Why can't the website find my microphone?

This usually happens if microphone permissions are blocked for this site in your browser settings. Make sure you've allowed access. You can also try selecting a different device from the dropdown menu if you have multiple microphones connected.
