# Camera, Mic & Speakers

Camera, microphone and speaker tests confirm that your devices work and that the browser can use them, which is worth checking before a video call or a recording. Common causes of a failed test are a blocked browser permission, another app using the camera or microphone, or the wrong input device selected.

## Tools

- Microphone Test (Coming soon): Check that your microphone picks up sound by watching the input level and playing back a recording.
- Webcam Test (Coming soon): Check that your webcam works and see the resolution and frame rate it delivers.
