Run a private sound test for left, stereo, and right output, then open guided audio diagnosis if something sounds wrong. Sound Test puts a quick speaker and headphone check in the Chrome toolbar. Choose Left, Stereo, or Right, play a controlled 1 kHz signal, and confirm whether the sound matched the selected output path. If a channel is silent, reversed, or unbalanced, open the relevant guided diagnosis on Online Sound Test for explainable causes and system-specific next steps. Main features: - Left, stereo, and right output checks - Local Web Audio signal generation - Adjustable app attenuation from −36 dB to −6 dB - Clear pass or check results based on what you confirm - Direct access to onlinesoundtest.com for deeper testing - No microphone, browsing-history, page-content, or site-data access - No accounts, extension analytics, advertising, or stored answers The extension verifies the digital signal it generates. You confirm what physically played through your speakers or headphones. It is not a medical hearing test, acoustic calibration, or automatic hardware detector.
