VVTetraVST

VVTetraVST is a VST plugin that converts the raw signals from a TetraMic, known as A-Format, and converts them to B-Format. This processing is performed using the individual calibration files for each TetraMic. The resulting signal can be processed in various ways, like rotation or zooming, and then converted the stereo, 5.1 or other formats with a decoder like VVMicVST
