About
SoundTestX is a free browser-based audio testing tool that lets users check whether their headphones or speakers are working correctly. It tests left and right channel output, stereo balance, frequency response from 20 Hz to 20 kHz, and includes tools like a tone generator, bass test, decibel meter, and audio latency test. No downloads or installations are required, and nothing is recorded or uploaded.
Problem
Users need a quick, no-install way to check if their headphones or speakers are working correctly and identify channel imbalance or frequency issues.
For
General consumers wanting to diagnose or verify their headphones or speakers
How it works
The tool runs entirely in the browser using the Web Audio API, playing tones and sweeps through the user's selected audio output to test left/right channels and frequency response.
