## Full description

Every test is synthesised live by the browser's own audio engine, so nothing is pre-recorded or streamed from a server. The site bundles more than 70 checks, including a stereo balance test, a polarity check that plays the same 80 Hz tone in phase and out of phase, a tone generator covering 20 Hz to 20 kHz, and a decibel meter with calibration offset. Microphone checks run locally in the tab, so audio is never uploaded.

A Firefox extension is also available: https://addons.mozilla.org/en-US/firefox/addon/soundschecker/
