⚠️ Start at a low volume, especially when using headphones. This test generates a short tone locally in your browser. Your operating system, browser, audio interface or device may affect stereo channel routing.
How to Test Your Speakers
- Lower your device volume before starting.
- Click Test Left Speaker and confirm the sound comes from the left side.
- Click Test Right Speaker and confirm the sound comes from the right side.
- Use Test Both Speakers to play through both channels.
- Adjust the test volume carefully if needed.
Why Is One Speaker Not Working?
If one side is silent, check the device connection, balance settings, output device and cable or Bluetooth connection. Mono audio settings can also make both channels behave differently from a normal stereo setup.
Frequently Asked Questions
Does this tool upload any audio?
No. The test tone is generated locally by your browser using the Web Audio API.
Can I use it with headphones?
Yes. Keep the volume low before testing to avoid unexpectedly loud sound.
Why do I hear both tests from both sides?
Your device may be using mono audio, a non-stereo output, or software that changes channel routing.
