Questions people ask
- How do I test my camera and microphone before a video interview?
- Open a browser test page like this one, allow camera and microphone access, and check four things: that your camera delivers at least 720p, that your microphone registers when you speak, that your room is quiet, and that your face is lit from the front rather than from behind. Doing it in a browser matters — the interview itself will run in a browser tab, so testing in your operating system's settings can pass while the tab still fails. Close every other app holding the camera first; a second app with the camera open is the single most common cause of a black preview.
- Why does my webcam look dark or grainy on interview calls?
- Almost always because the brightest thing in the room is behind you. A webcam exposes for the overall frame, so a window or lamp behind your head makes the camera darken everything, and your face becomes a silhouette. The fix takes ten seconds: put the light source behind your screen so it faces you, and close the blinds behind you. Grain rather than darkness usually means the same thing — the camera is compensating for low light by raising its gain.
- My microphone shows as connected but nobody can hear me. Why?
- A connected microphone and a working microphone are different things. Three causes cover most cases: a hardware mute switch on the headset or its cable, a mute key on the keyboard, and the browser using a different input device than you think — a laptop's built-in mic while you speak into a headset, for example. Check the mute switch first, then open the input-device list and select the microphone you are actually speaking into, then test again and watch for a level meter that moves when you talk.
- Do I need to test anything if I already used this laptop for a call last week?
- Yes, and it takes less time than reading this answer. Operating system updates reset default input and output devices, other applications hold the camera open after they are closed, and the light in a room changes completely between morning and evening. The check is worth running in the same room, at the same time of day, and on the same network you will use for the interview itself.
- Is anything uploaded or recorded when I run this check?
- No. Every measurement runs in your browser: the camera frame is drawn to an off-screen canvas and reduced to a brightness number, and the microphone level is measured with the Web Audio API. No image, no audio and no recording is sent to withLyra, written to a server, or stored anywhere. The camera and microphone are released the moment the check finishes.
