About This Launch
SoundsChecker is a free site with over 70 browser audio tools, including speaker, microphone, bass, tone generator and surround tests. Play tones from 20 Hz to 20 kHz and switch the signal left, right or both to check stereo balance. No sign-up needed.
Why I Built This
I kept needing a fast way to check speakers and stereo balance without hunting for test pages, so I built one site with the tests in one place.
