About SoundsChecker

Most online sound tests are cluttered, slow or vague about what they measure. We wanted one place where anyone can check speakers, headphones and microphones in seconds and get honest, practical next steps.

Every tool generates its signals with the Web Audio API at your device's native sample rate, so nothing is pre-recorded or compressed. Before each release we check every tool in a current desktop browser for errors and correct behaviour, and we are expanding our testing to more browsers, operating systems and audio devices. Where a browser or device can't do something, such as discrete surround on a stereo-only output, the page says so plainly. If a tool misbehaves on your setup, please tell us.

• Private: audio never leaves your device.
• Fast: lightweight static pages, no heavy frameworks.
• Honest: we explain limits and never present estimates as lab measurements.
• Accessible: keyboard-operable controls, good contrast, dark mode.
