Stereo Imaging
Speaker tools generate test tones locally with the Web Audio API. Start at a comfortable volume.
Stereo Imaging Test: Soundstage, Center Image, Left Right Placement, And Headphone Spatial Check
Test stereo imaging, panning, and speaker placement with moving tones.
What this test checks
- Browser audio output
- Channel direction or tone response
- Frequency, bass, or stereo imaging behavior
- Check Left Right Width And Separation
How to read the result
Stereo Imaging uses browser audio playback. Keep volume comfortable, test left/right balance, and compare sweep, bass, and imaging pages if you hear distortion, swapped channels, weak lows, or unstable stereo placement.
Play A Stereo Placement Pattern
The test uses left, center, and right audio cues so users can hear whether the soundstage is balanced and properly centered.
Listen For A Stable Center Image
A centered sound should appear between the speakers or in the middle of headphones. If it pulls to one side, balance, placement, or channel routing may be wrong.
Check Left Right Width And Separation
Good stereo imaging makes positions feel distinct without collapsing into mono. This is useful for music, gaming footsteps, video editing, and speaker setup.
Compare Headphones And Speakers
Users can replay the imaging test across different audio devices. Comparing results helps identify whether the issue comes from headphones, speakers, room placement, or software settings.

What does Stereo Imaging measure?
Test stereo imaging, panning, and speaker placement with moving tones.
Do I need to install anything for Stereo Imaging?
No. Stereo Imaging runs directly in a modern browser. Some checks may ask for permission when they need camera, microphone, gamepad, pointer lock, touch, or audio output access.
Are results uploaded?
The test runs in your browser and uses local input events or browser hardware APIs for the visible diagnostics.
Why should I run related tests too?
Related tools help separate hardware issues from browser timing, display behavior, input device settings, or permission problems, which makes the final diagnosis more useful.
Detailed Testing Guide
Audio-output symptom
This speaker page checks one output behavior: channel direction, sweep response, bass, or stereo image.
Start with a baseline run before changing device settings. Record any repeated symptom so the next comparison is useful.
Listening evidence
Listen for direction, audibility, distortion, rattling, low-frequency response, and center image placement.
Watch Browser audio output, Channel direction or tone response, Frequency, bass, or stereo imaging behavior, Check Left Right Width And Separation. These observations come from the browser; they do not reveal hidden firmware or factory calibration data.
Playback method
Start at low volume and confirm the operating-system output device before playing tones.
Keep the test conditions stable. Changing browser, cable, port, lighting, surface, volume, grip, or selected device all at once makes the result harder to trust.
Result reading
Small speakers, Bluetooth routing, room reflections, and unsafe volume can mislead the result.
A repeated pattern matters more than a single spike. When something looks wrong, confirm it with another pass and compare a related tool before deciding the device itself is defective.
Limits and next checks
Use left/right, frequency sweep, bass, and stereo imaging pages together.
