Stereo output bench
Ready for a stereo listening test
Play left, right, and both at a low system volume. MeterSee generates the tone locally and asks you to verify the physical output.
Start at low system volume. Each tone stops automatically after three seconds. This test confirms audible routing and stereo separation; it does not measure speaker frequency response or distortion.
Isolate routing before replacing a speaker.
Compare channels at a low, identical volume. A missing channel can come from balance settings, a cable, an interface, or the speaker itself.
Check physical outputs first, then the operating-system balance and channel map.
Play both, reseat the connection, and test headphones on the same output.
Lower both system and test volume; compare another browser and output device.
Speaker channels
How this test works
The browser generates a defined tone for the selected channel. Your listening confirmation establishes whether the intended output is audible.
What this cannot establish
The site cannot hear your speakers or measure their acoustic quality. Start at low volume; if one side is silent, check output selection, system balance, and cables before repeating.
Recheck before replacing hardware
Change one variable at a time, repeat under the same conditions, and compare with the operating system or the affected application. An unavailable reading is not a pass.

- Google Meet has no sound: identify the missing audio path firstNo sound can mean that you cannot hear a meeting, nobody can hear you, or a shared video is silent. Those are separate audio paths and should not be repaired with the same checklist.
- Bluetooth audio delay: find which part of the listening path is lateA late sound can come from Bluetooth buffering, a video player's synchronization, a game's processing, or the return path of a call. A controlled comparison is more useful than a universal latency fix.
