Google today updated the SDK for Google Cardboard and added support for spatial audio. Until today, Cardboard apps were limited to stereo sound.
The addition of spatial audio will allow developers to create more immersive sound environments to match their VR experiences. Google says the SDK lets developers specify the size and material of their virtual environment, which impacts how sound moves around objects and to the listener’s ears. Adding spatial audio will have minimal impact on CPU performance needs, so it shouldn’t affect battery life.
The Unity version of the SDK can be used to bring spatial auto to Android, iOS, Windows, and OS X devices, while the native Android SDK will require only a simple Java API. Developers can download the updated SDK directly from Google.
