The PSFC, or Pioneer Sound Field Control
is a DSP-driven hemispherical 14-loudspeaker array,
installed at the University of Aizu Multimedia Center.
Collocated with a large screen
rear-projection stereographic display,
the PSFC features realtime control of virtual room characteristics
and direction of two separate sound channels,
smoothly steering them around a configurable soundscape.
The PSFC controls an entire sound field,
including sound direction,
and simulated environment (reverb level, room size and liveness)
for each source.
It can also configure a dry (DSP-less) switching matrix
for direct directionalization.
The PSFC speaker dome is about 14 m in diameter,
allowing about twenty users at once to comfortably stand or sit near its
