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.

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.
