How to use this test
Check left, center and right channels, then listen to stereo, bass and treble sweeps. Start with low system volume. Phase comparison is available in technical details.
What the results mean
Channel sounds should come from the selected side; sweeps let you compare movement and tonal balance.
Troubleshooting
Check mono audio, spatial effects and channel balance if the sides sound identical or reversed.
Browser limitation
Audibility depends on your hearing, age, equipment and system processing. The theoretical frequency range is not a hearing diagnosis or a guarantee of output. Mono audio, spatial effects or channel swapping can change the result; check these settings and stop if uncomfortable.
