Speaker Test – Left, Right and Center Audio
Check whether your speakers or headphones are working properly in seconds. Test the left, right and center audio channels, verify the stereo balance and quickly detect missing, reversed or unbalanced sound.
How to test your speakers or headphones
First, select the audio channel you want to test. The left, center and right channel options allow you to check whether both sides of your speakers or headphones are working correctly. Once the sound starts playing, listen to the channel balance to quickly identify audio loss, imbalance, reversed channels or connection problems.
1. Select a channel
Start the test by selecting the left, center or right audio channel.
2. Play the sound
Check whether the test sound is coming from the correct side.
3. Verify the balance
Determine whether there are any problems with the stereo balance.
Frequently Asked Questions
What does the speaker test do?
The speaker test helps you check whether the audio output is working properly and whether there are any issues with the balance between the left and right channels.
What can I check with the headphone test?
You can check whether sound is coming from both sides, whether the channels are routed correctly and whether the stereo balance is working properly.
Why are the left and right channels tested separately?
In some cases, sound may only come from one side or the channels may be reversed. Testing each channel separately helps you detect these issues quickly.
Does this test work on mobile devices?
Yes, it can be used in supported mobile browsers. However, checking individual audio channels is generally easier on a desktop or laptop.
How do you verify a suspicious result?
Start at low volume. Confirm that the left channel plays on the left and the right channel on the right, then listen to both together. If one side is silent, check operating-system balance, the headphone plug and the Bluetooth connection separately.
If both sides play the same sound
The mono-audio accessibility setting can combine both channels. Some built-in speaker arrangements also make left and right difficult to distinguish physically. Compare stereo headphones and report the side you hear, not just the button you selected.
The tool does not automatically measure your speakers with a microphone. Its summary uses selected channels and your feedback; it is not a frequency-response or professional audio-quality report.
