Only the measurement and review summary stays in this browser for 7 days for Device Check and JSON reports. No photos, video, audio or screenshots are stored. Denied permission and unfinished tests are not faults. Visual and listening reviews are labeled as user reports.

The meter shows relative digital signal, not decibels or audio quality. Silence alone is not a fault.

Test guide

What this test proves—and what it cannot

The microphone test opens a live audio input and calculates a visual level inside the browser. It helps distinguish permission and input-selection problems from a silent, muted, disconnected, or very low-level source without recording or sending speech.

Signals measured

Whether microphone permission and a browser audio stream are available
Relative live signal level, not calibrated sound pressure
Browser-exposed sample rate, channel count, and device label when available
User-observed response while speaking, tapping, or changing input

How the test works

The stream starts only after a user action and browser permission decision.
Web Audio analyzes short live samples to draw the level meter.
No recorder, speech recognition, transcript, or upload is created.
Audio tracks and analysis are stopped when the user finishes or leaves.

Interpreting the results

SignalWhat it meansNext step

Meter respondsThe selected input reaches this browser with measurable activity.If another app fails, check its device selection, mute, and permission.

Permission not grantedThe browser did not open an input; hardware state remains unknown.Review site and OS privacy permissions before retrying.

Flat or very low meterA stream may be open but carry little usable signal.Check mute, gain, selected input, cable, adapter, and another application.

Measurement limits

The meter is relative and cannot certify studio quality, frequency response, or exact decibels.
Browser noise suppression and automatic gain can change the visible level.
A working input stream does not prove that every calling app uses the same microphone.

Missing or privacy-reduced detail is not scored as a fault by itself.

Questions about this test

Does the test listen to or transcribe what I say?

No. It calculates a numeric signal level locally. There is no speech recognition, recording, storage, or upload.

Why does the meter move when the room is quiet?

Microphone self-noise, fan noise, electrical interference, automatic gain, and ambient sound can create a small baseline.
