Harpex Audio GmbH develops Harpex, a sound-field processing plug-in and related software for ambisonic and surround audio production. Its products are used by content creators working with sound-field recordings for film, television, VR and AR, and for headphone, stereo and multichannel surround playback; third-party documentation also describes the Harpex algorithm as a way to synthesize higher-order ambisonics from recorded sound fields. The company’s own materials and a public demo identify Harpex Audio GmbH as the organization behind the Harpex-B processor and the spcmic high-resolution 3D audio capture system, which uses 84 calibrated MEMS microphones and software-configurable beamforming. Publicly available sources also show Harpex Audio GmbH as the developer of the Harpex plug-in line, but they do not consistently provide verified founder names, current executives, funding details, or a reliable headquarters city across primary sources, so those details are omitted.
