Audio Shifting Adjustable
Summary in Plain English
Audio that pans or shifts between channels to simulate movement must be something a user can pause or switch off. It does not apply when the shifting comes from the operating system or the browser rather than from the content.
Why It Matters
Simulated motion in sound can provoke nausea, disorientation or vestibular symptoms, and it makes speech harder to follow for people who process audio with one ear or with a hearing aid.
