❓ Frequently Asked Questions

Is my camera feed or audio recording sent to any remote server?

No. All video rendering, frame-rate calculations, and audio volume analysis run 100% locally inside your web browser using WebRTC and Web Audio API.

Why is the webcam or microphone not working in the test suite?

Please ensure you have granted camera and microphone permissions in your browser's site settings, and that no other application (like Zoom or Teams) is exclusively locking the hardware.

How does the microphone volume meter work?

The VU meter analyzes audio frequencies captured by your microphone in real-time using an AudioContext AnalyserNode and displays a dynamic volume level bar.
