Tools for video calls: mic, camera, speakers

Open the mic check first and speak at normal volume. You want a moving meter without clipping. If the peak sticks at the top, drop input gain in the OS, not in the meeting app.

Then the camera: lighting from the front beats a window behind you. The preview is the same feed the call will use, so a frozen frame here means a frozen frame there.

Finish with the speaker test: left/right and a tone. Bluetooth headsets often need a second permission prompt. Latency in the mic studio is a hint if you hear yourself delayed.

Before a call, check the mic level while the room is quiet, then while you talk. Headphones stop the speaker test from feeding back into the mic. A camera preview tells you if the lens cap, a virtual camera, or a dark exposure is the problem. This page groups those three checks. Each one still has its own tool page with the steps and the FAQ.
