Ready for a short test tone.
What this test is best for
This page is a channel-routing test, not another copy of the speaker cleaner. Use it after cleaning to confirm whether audio is balanced, or before troubleshooting Bluetooth and laptop output settings.
Common results
- Left and right are clear: stereo output is working.
- Both sides sound centered: mono audio may be enabled or the device has limited stereo separation.
- One side is missing: check audio balance, Bluetooth routing, or device speaker hardware.
Next steps after testing
If you find one side is quieter, try the speaker cleaner on the affected side. For call audio issues specifically, use the ear speaker cleaner. If you suspect the speaker is fine but volume is low overall, check our volume fix guide.
Foire Aux Questions
Is this a full cinema surround test?
This browser tool focuses on practical left, center, and right channel checks. Most phone and laptop browsers expose stereo output rather than true home-theater surround channels.
Why does left and right sound the same on my phone?
Many phones have tiny speaker spacing, mono accessibility settings, or speaker routing that makes left and right hard to separate. Test with headphones only at low volume.
Can this find Bluetooth speaker problems?
Yes. If the center tone plays but left or right behaves strangely, check Bluetooth mode, audio balance settings, and paired device configuration.
