What is SpeakerSoundTest?
SpeakerSoundTest.com is a collection of free online tools for checking speakers, headphones, earbuds and subwoofers. Every test runs directly in your web browser. There is nothing to install, no account to create and no audio is ever recorded or uploaded.
Our tools
- Speaker Test – check left, right and stereo output, bass and treble.
- Headphone Test – check channels, phase, bass and frequency range of headphones and earbuds.
- Bass Test – play tones from 20 to 200 Hz and run subwoofer sweeps.
- Left Right Audio Test – make sure your stereo channels are correct and balanced.
- Tone Generator – create any frequency from 1 Hz to 20,000 Hz.
How it works
All sounds are generated in real time on your own device with the Web Audio API, a standard feature of modern browsers. Because the sound is created mathematically rather than played from a compressed file, the tones are exact and the tests work the same on phones, tablets, laptops and desktop computers.
Why we built it
Most people only notice an audio problem when something already sounds wrong: dialogue coming from the wrong side, a missing bass line, or a crackle in one ear. We wanted a simple, fast and honest place to find out what is going on, with clear explanations of what each result means and how to fix common problems.
Hearing safety
Test tones can be louder than they seem, especially at very low and very high frequencies. Always start with low volume and increase it slowly. See our terms of use for more details.
