About OPSODIS
OPSODIS is a 3D audio reproduction technology jointly developed by Kajima Corporation and the University of Southampton’s Institute of Sound and Vibration Research. The name derives from the acoustic theory term Optimal Source Distribution.
The system combines proprietary signal processing, including crosstalk cancellation, with a symmetrical speaker layout that places high-frequency drivers near the center axis. This configuration delivers a natural and precise three-dimensional sound field. Unlike conventional spatial audio systems that depend on wall or ceiling reflections, OPSODIS projects sound directly to the listener, recreating accurate spatial cues in all directions.
