Check your camera, microphone and speakers before a call or while building a WebRTC app. Live preview, level meter, test tone and full device list. Nothing is recorded or uploaded.
The preview stays on this page only. When you press stop, or close the tab, the camera is released.
Speak normally. A healthy speaking level sits in the good zone. If the bar barely moves, check your input device and system volume.
Left and right buttons play the tone in one channel only, useful for checking stereo wiring and headset orientation.

Whether you are about to join an important video call or you are building a WebRTC application, the first question is always the same: do the camera, microphone and speakers actually work? This tester answers that in seconds. The camera panel shows a live preview with the real resolution and frame rate your browser negotiated. The microphone panel meters your input level in decibels and warns you about clipping. The speaker panel plays a pure test tone into the left channel, right channel or both, which instantly reveals swapped or dead channels on a headset.
For WebRTC developers, the device table lists every videoinput, audioinput and audiooutput device that enumerateDevices exposes, along with the resolution and channel capabilities reported by the browser. It is a quick way to confirm what your own getUserMedia code will see on a given machine.
