Three-part soundfield decomposition for stereo encoding

We introduce a codec that embeds a full 3D audio scene into a simple stereo-compatible stream which can be compressed with standard lossy compression schemes, aired to FM stations or even stored on analog supports. The encoded stream can be decoded and rendered to virtually any format. We detail the spatial analysis that decomposes the periphonic soundfield into three components and reduces it to a monophonic spherical representation, and its encoding to a stereo carrier.
