AudioTestHQ is a free collection of audio tests that run entirely in your web browser: speakers, left and right channels, headphones, bass, surround sound, microphone, polarity and latency. It is built and maintained by Sri Murugan Systems, an independent software developer.
Why it exists
Most sound-test pages play a beep and leave you to guess. When something is wrong you need to know what: which side, which speaker, how much noise, how much delay. So each test here asks you a simple question or takes a real measurement, and ends with a result card you can keep or send to whoever is helping you.
Principles
- The test is the page. The first thing you see is a working test.
- Honest limits. A browser cannot measure everything. When it can't, we say so.
- Safe by default. Tests start at 20% volume and every sound passes through a limiter.
- Private. Nothing you play or record leaves your device.
