Device tests
Check that a keyboard, microphone, webcam or screen works, in a minute and without installing anything. Each test reads the device inside this page, so nothing is recorded or sent.
Tests

- Mic testTest your microphone in the browser: live level meter in dBFS, waveform, device picker, and a 5-second record and playback.
- Webcam testCheck your webcam in the browser: live preview, real resolution, measured frame rate, camera picker, mirror and snapshot.
