Harpex is a signal processing algorithm designed to extract the maximum amount of spatial information from sound field recordings. With the Harpex plug-ins, content creators use this technology to transform sound field recordings in A-format, B-format or AmbiX into the standard surround and 3D surround formats used in film and television, coincident, non-coincident and binaural stereo, or higher-order AmbiX for VR and AR applications.
