You slave over trying to match the 3D visuals of the Oculus Rift with its audio equivalent, and then what do you do for a promotional image? Someone in an Oculus rift and earphones, and a pair of rendered speakers. Job done. Fortunately, Divemachine is making good progress with its immersive audio system. While VR headsets continue to get better at movement detection and the whole visual-realization-of-a-3D-space thing, audio's not had so much attention lavished on it. Genetec's Divemachine platform involves collaboration with environmental sound designers, and connects Oculus Rift headset movements to audio, creating what it's calling full 3D sound.
