Immersive audio is particularly important in an era where games are mainstream and virtual reality is quickly catching on, but there isn't a common framework for it. What works on your PC may be useless on your phone. Google wants to fix that: it's launching Resonance Audio, an open source developer toolkit that brings spatial audio to games, VR, AR and 360-degree video across many devices and platforms: Android, iOS, macOS, Linux and Windows are all covered. The technology borrows from Google's VR Audio kit to spatialize "hundreds" of 3D sound sources in real time, even on low-powered hardware like your smartphone. And depending on where it's running, it can even produce clever effects with a relatively low performance hit.
