ARCADE spatial audio codec

ARCADE is a patented spatial audio codec that allows encoding scene-based 3D audio over stereo with no additional metadata required. It allows encoding sources with height in a fully spherical manner. Its decoder is able to decode to virtually any 3D or 2D audio format, for example first-order or higher-order spherical harmonics (
FOA, HOA), VBAP, Surround, Binaural with or without head-tracking etc. The decoder also works as an upmixer for any stereo content, to any of the formats it can decode to.
