About Mic and webcam test
Mic and webcam test is a free set of hardware tests that run entirely in your browser. We built it to answer the question "is it my device, my settings, or the app?" in under a minute, with real numbers instead of guesses.
What we do
Each test shows what it measured, explains what that means, and lists what to try next. No accounts, no uploads, nothing to install.
- Media testing: Microphone, webcam and speakers with live waveforms, real levels, FPS and lighting analysis.
- Hardware & input: Keyboard mapping, mouse button tracking and game controller axis and button listeners.
- Mobile & display: Touch grid, multitouch, vibration, sensor telemetry, dead pixel sequences and a calibrated ruler.
- Utility tools: A private dictaphone that records straight to MP3 for up to two hours, all on your device.
Our principles
- Private by design. Audio, video and input are processed on your device and never uploaded.
- Free and instant. No sign-up, no downloads, no paywall.
- Honest results. We show what was measured and say plainly when a result is inconclusive.
