Check left & right stereo
Verify that the left and right channels play correctly. If the sound comes from the wrong side the channels are swapped; if there is no sound at all there is a fault or wiring problem.
Speaker Test
Test your speakers or headphones online in the browser. Play a test tone on the left, right or both channels.
For headphones & speakers
Works for headphones, headsets and speakers alike. The tone is generated in the browser via the Web Audio API — no download and no installation.
Frequently asked questions
How do I check whether the channels are swapped?
Play the left and right test tones separately. If the sound comes from the wrong side, the channels are swapped.
I hear no sound — why?
Check the volume and the selected output device. Some browsers require playback to be started by a click first — which the test-tone button does.
