Google’s Cardboard division, the group in charge of the development of the company’s Virtual Reality Platform recently announced that they’re updating the SDK of the platform to allow for spatial audio to be added into developers’ apps. Spatial audio—or 3D or binaural audio—is designed to allow sound to shift between channels when you move the position of your head to create an immersive audio experience. The new SDK for Cardboard doesn’t just allow developers to determine the relative position of sound, they can also emulate the material and size, even with having to work on a smartphone CPU. So, the next time you use an app with Cardboard, you might even be able to hear things like planes flying by.
