Match the bounce to the beep

Start the animation, then move the offset slider until the impact flash and the short beep feel perfectly simultaneous. The selected offset is your perceived headphone latency.

Understand your results and improve your setup

A good test should not stop at a score. Use these practical checks to understand what the browser measured, what can affect the result, and what to change before your next call, stream or gaming session.

What latency means

Audio latency is the delay between an event and the sound reaching you. Bluetooth codecs, operating-system buffering, browser scheduling and the audio device all contribute.

Interpret with caution

Browser timing is useful for comparisons on the same device but is not a substitute for loopback hardware measurement.

Why CamMicGo goes further

✓ Private by design: tests and recordings are processed locally in your browser whenever possible.
✓ Multilingual by design: the same diagnostics and explanations are available across CamMicGo languages.
✓ Practical diagnostics: CamMicGo focuses on repeatable browser measurements and explains their limits instead of presenting them as laboratory certification.
