In our system, a PC manages the DSP of the PSFC System, and a HP workstation functions as an interface for the PC. However, an application program runs on an SGI (Onyx) workstation, so controlling the PSFC system from the remote host is needed.
We designed a client-server model for communication between the HP and the SGI, including an API for sound spatialization. The server accepts the original ten functions of PSFC System, as well as an additional command, ``distance''.
