Sound-Tester
Check your speakers, headphones, and microphone in the browser without installing anything.
About
Sound Tester runs audio checks online for free. You can test speakers, headphones, and microphone input, plus stereo sound, bass, frequency, and audio latency. No download is required.
How to use
Open sound-tester.com in your browser. There is nothing to download and nothing to install, so the checks run on the page itself.
Pick the check you need. You can test speakers and headphones, check microphone input, and run tests for stereo sound, bass, frequency, and audio latency. If you are setting up a new headset before a call, the speaker and microphone checks are the usual starting point. If you are troubleshooting sound that seems off rather than missing, the stereo, bass, and frequency tests give you something concrete to listen for.
What you get out of the Sound-Tester utilities app is a quick answer about whether your audio hardware is doing what you expect, without committing to a software install. The results tell you what you hear, so you can decide whether the problem is the device, the cable, or a setting elsewhere on your system.
Before a microphone check, make sure your browser has permission to use the microphone, since browsers ask for that separately from the page itself.
