We propose a perceptually-based approach to creating immersive soundscapes for VR applications. We leverage stereophonic content obtained from XY microphones as a basic building block that can be easily recorded, edited, and combined to provide a more compelling experience than can be obtained from recording at a single location. Central to our approach is a novel up-conversion algorithm that derives a nearly full-spherical parametric soundfield, including height information, from an XY recording. This approach enables a simpler, improved capture, when compared to alternative soundfield recording techniques. It can also take advantage of new object-based delivery formats for flexible delivery and playback.
