Human beings experience sound in all directions—like when a fire truck zooms by, or when an airplane is overhead. Starting today, the Cardboard SDKs for Unity and Android support spatial audio, so you can create equally immersive audio experiences in your virtual reality (VR) apps. All your users need is their smartphone, a regular pair of headphones, and a Google Cardboard viewer.
Many apps create simple versions of spatial audio—by playing sounds from the left and right in separate speakers. But with today’s SDK updates, your app can produce sound the same way humans actually hear it. For example:
We built today’s updates with performance in mind, so adding spatial audio to your app has minimal impact on the primary CPU (where your app does most of its work). We achieve these results in a couple of ways:
It’s really easy to get started with the SDK’s new audio features. Unity developers will find a comprehensive set of components for creating soundscapes on Android, iOS, Windows and OS X. And native Android developers will now have a simple Java API for simulating virtual sounds and environments.
Check out our Android sample app (for developer reference only), browse the documentation on the Cardboard developers site, and start experimenting with spatial audio today. We’re excited to see (and hear) the new experiences you’ll create!
