What this mic test measures
Peak shows the highest instant level. RMS is the average loudness over time. Aim for strong RMS without constant 100% peaks. If peaks hit 100% and the sound distorts, lower sensitivity or move the mic farther from your mouth.
Privacy & permissions
Audio stays on your device and is processed in your browser. Nothing is uploaded or stored. To revoke access, open your browser’s site settings and remove the microphone permission.
Keep troubleshooting
- For a minor splash affecting only the loudspeaker, see our water-eject guidance after the device is safe to use. Speaker tones do not dry microphone internals.
- Run the speaker test to check for distortion, rattles, or imbalance.
- Try a quiet room and move cables/adapters—ground loops and loose jacks can cause hum or buzz.
- On Windows or macOS, open system sound settings and ensure the correct input is selected and not muted.
Microphone, browser permission, or call problem?
Use this live meter in a quiet room, then compare it with your phone's built-in voice recorder and a call or video recording when safe. This page displays live sound levels; it does not save recordings.
- Meter not moving only here: Check browser microphone permission and the selected input device.
- Voice recorder also sounds muffled: Remove the case, inspect the external microphone opening on a dry phone and test again.
- Recording clear but calls are bad: Check mobile signal, Bluetooth headset routing and app settings.
- Phone recently soaked or malfunctioning: Stop testing, avoid charging and seek device-specific guidance or service.
A browser cannot select or diagnose every microphone on a multi-microphone phone, and a moving audio meter cannot rule out liquid damage.
