Test Haut-parleurs

Test Haut-parleurs

Play left/right tones and sweeps to check stereo speakers or headphones.

Tons gauche/droite et balayage de fréquence.

What this test checks

This test plays left, right, stereo, fixed-tone, and frequency-sweep signals so you can check channel assignment, audibility, obvious distortion, and interruptions.

How to interpret results

Left and right controls should sound from the matching side. A clean tone or sweep without rattling, dropouts, or unexpected channel mixing suggests the current browser output path is working.

Limitations

This is a subjective listening check, not calibrated acoustic analysis. Hearing range, room acoustics, volume processing, wireless codecs, and speaker design affect what you hear.

Troubleshooting

Start at low volume, select the intended output in system settings, disable spatial or enhancement effects, reconnect headphones or speakers, test each channel, and compare another audio source.
