Personalized Spatial Audio uses your iPhone's camera to scan your ears and create a custom sound profile just for you. It sounds weird, but it actually makes a noticeable difference in how immersive music and movies sound.
The app will have you slowly turn your head left and right while it captures your ear shape in 3D. Takes about 30 seconds total.
Your iPhone is mapping the unique curves and shapes of your ears. This matters because Spatial Audio simulates 3D sound, and everyone's ears filter sound differently. With your personal profile, the virtual speakers are "placed" more accurately for your specific head.
