Microphone clipping test
Observe repeated peaks near digital full scale while you speak.
Diagnostic visuals retain their original colors and remain visible. Presentation filters and high contrast apply outside this workspace; device-level filters may still affect your observation.
Start the microphone and speak at your normal and louder levels for at least three seconds.

How to run this check
Start the microphone and speak at your normal and louder levels for at least three seconds.
Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
Three sampled windows with a peak at or above 0.99 indicate possible clipping. Unsampled peaks can be missed; processing changes the signal.
If something seems wrong
Reduce input gain, increase microphone distance slightly and repeat at the same speaking level.

Is anything uploaded?
Raw diagnostic input and media are processed locally. Standalone results remain in page memory. Guided checks offer optional coarse session recovery for 24 hours; it excludes media and detailed measurements. Hosting and Google Analytics requests still leave your browser. Analytics receives only broad test-usage categories, never these diagnostic contents. See the privacy policy.
Does a pass guarantee my hardware is healthy?
No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
