Living Worlds predicted how real rooms sound in arrangements and positions nobody had measured, and how daylight falls on office desks on days nobody had read: met for a room never seen (20 of 20), four rooms never seen (4 of 4), sound beyond what was measured and daylight at the desk; not met in a second room.

Spatial audio got a full international standard in 2025, wave-based simulation reached open datasets, and learned acoustic fields now predict how a room sounds from a handful of measurements. The open question is how far those predictions hold beyond what was measured, and how to show it.
