Spatial Sound Audio

When objects are out of our line of sight, one of the ways that we can perceive what's going on around us is through sound. Given that are hologram objects made of light and sometimes sound, the sound component helps ground holograms making them more believable and creating a more immersive experience. By analysing how sound reaches both our ears, our brain determines the distance and direction of the object emitting the sound. An HRTF (or Head Related Transfer Function) simulates this interaction by modelling the spectral response that characterises how an ear receives sound from a point in space. The spatial audio engine uses personalised HRTFs to expand the mixed reality experience, and simulate sounds that are coming from various directions and distances.
