Good to know

Privacy and browser limits

Most readings come directly from browser APIs and stay on your device. Operating systems, browser permissions, scaling, drivers, and hardware can affect what a page can observe.

For the cleanest result, use an up-to-date browser, keep the tab visible, and close apps that may already be using the device.

FAQ

Questions about the microphone test

Is my test data uploaded?

No. This test runs locally in your browser. RatedTechTools does not receive or store the device data shown by the tool.

Is the level a calibrated decibel reading?

No. It is a relative digital signal level, useful for comparing silence, normal speech, and clipping—not acoustic dB SPL.

How long can I record?

The built-in test stops automatically after 20 seconds to keep the tool lightweight and local.
