Yes, it's completely free to use with no registration or login required. All features are available with no usage limits.
No. This tool runs entirely in your browser locally. All audio data stays on your device and is never uploaded to any server.
The tool needs access to your microphone to test it. Your browser will show a permission prompt β simply click Allow. If you accidentally denied it, change the permission in your browser's site settings.
When you speak, the volume level bar should jump above 50%. If the bar doesn't move at all, your microphone may not be working properly. Green means normal levels, red means the audio might be too loud.
Possible reasons: 1) The mic is being used by another app (Zoom, Skype, etc.); 2) Browser permission was denied; 3) Hardware issue or the mic is muted; 4) Wrong audio input device selected in your system sound settings.
