The Apple Glass, an AR headset, may offer a few interesting features. To make the whole experience more immersive it could offer an accurate reproduction of sounds on a 3D plane, according to a report from AppleInsider.
Virtual reality in gaming and augmented reality has become increasingly more popular in recent times, and the people behind such technology are constantly trying to make the world you see more believable. The latter in particular has revolved around bringing more to the mundane world around the user. Thus, the added realism from the accurate audio could make digitally created structures seem more genuine.
This could also help improve interactions with said artificially produced objects in the users’ vision. While most stereo headphones offer basic left and right differentiation, a virtual sound system can reproduce audio positioning on a 3D plane by altering the properties of the sound effects to mimic the distortions caused by different factors.

The Apple patent titled “Head related transfer function selection for binaural sound reproduction,” points at such a system. In simpler terms, the Cupertino based giant seeks to improve 3D sound positioning by having Head related transfer function (HRTF), which is basically a pair of acoustic filters for each ear. These help in differentiating the transmission of sounds from various positions in the environment around the user.
Unfortunately, the Apple patent does show the company’s interest in this field. Although, it does not provide any guarantee that the company would work on such a system. Rather, it could be their efforts in covering various bases for future possibilities which are again unlikely.
