About 3D sound reproduction system “OPSODIS”
Only the front theater bar system delivers sound in all directions, allowing you to experience the immersive sound as if
you were there.
OPSODIS principle
Humans ears can determine spatial information such as direction and distance just from sound it sensed.
However, in normal stereo playback, this spatial information is hard to get as the sound from left and right speaker get mixed during its travel
from speakers to ears.
OPSODIS with its original algorithm is able to deliver the sound to ears without getting mixed on the way. This allows the spatial information to
be clearly replicated with just front speakers.
<OPSODIS>
OPSODIS can transmit spatial information because it erases the sound waves you do not want to deliver
and delivers only the sound waves you want to deliver.
<stereo>
Sound waves reach each ear from both left and right speakers, making it difficult to convey spatial
information.

OPSODIS is a three-dimensional audio technology jointly developed by Kajima Corporation and the University of Southampton. Kajima
Technical Research Institute has a wealth of experience in architectural acoustics, such as the design of concert halls and music studios. The
Institute of Sound and Vibration Research at the University of Southampton is a world leader in acoustics and conducts cutting edge research
in many areas of the field.
The OPSODIS technology is capable of virtually realising spatial sound and was originally used to study the acoustic performance of
architectural spaces during the design stage. The sound bar home theater system uses the OPSODIS technology to accurately simulate
many three-dimensional audio formats commonly used in TV, cinema and gaming.
