While graphic fidelity goes a long way toward creating realistic, immersive, and compelling experiences in VR, sound also plays an important role. We recently introduced some significant breakthroughs in spatialized audio to the Rift SDK, including Near-Field HRTF and Volumetric Sound Sources. Today, we’re excited to share what these changes mean and introduce you to members of the team that’s making it all possible.
