Audio & Sound

Sony received 3 patents that address different dimensions of spatial audio for gaming. The first tackles the problem of audio clutter during multiplayer sessions by detecting silent gaps in primary chat channels and inserting supplemental audio like local commentary into those pauses, using directional sound placement to prevent conflicts. A second patent describes a positioning system that tracks the location of headsets and controllers by analyzing spread-spectrum audio signals, calculating position through pseudo-distance differences as the device moves rather than requiring synchronized clocks across transmitters. The third patent adapts game audio in real time based on individual hearing characteristics, pulling from audiogram data and biometric sensors like EEG or heart rate monitors to automatically adjust or replace specific sound types such as explosions or shouting without manual configuration.

Roblox received 1 patent for spatialized audio in virtual worlds. The system transforms flat voice chat into 3D audio by combining real-time avatar data like position and movement with the geometry of virtual spaces, applying acoustic physics models that account for occlusions, reverberations, and distance to make voices sound as though they originate from an avatar's actual location in the environment.
