The VP-8 is the industry’s first multi-mode audio processor with six built-in processing modes: FM, AM, FM-HD, AM-HD, MP3/AAC>48k, and MP3/AAC<48k. When operating in one of its six modes, special processing algorithms designed by Vorsis condition the audio appropriately for the selected transport medium. Audio is first preprocessed by a phase-linear four band AGC, then by an eight band limiter and final limiter or clipper. The eight band and final limiter operation is different in each of the operating modes due to special conditioning algorithms embedded within it that have been tailored for the particular needs of the operating mode. Changing modes is as simple as selecting a new mode from within the Windows-based Graphical User Interface; no reboot is required.
