Sony Develops 3D Sound Middleware "S-FORCE 3D Sound Library" for
Reproduction of Three Dimensional Sound through 2-Channel Speakers
(Tokyo, Japan) - Sony Corporation today announced the development of
middleware for PlayStation®2 titles named "S-FORCE 3D Sound Library"
that can reproduce the dynamic sound by simply connecting the L/R 2-channel
audio AV output on PlayStation 2 to a stereo television or stereo active
In recent years, improvements in 3D (CG) processing technologies for
characters, objects, etc. have enabled computer game images to become
more vivid and three-dimensional. Along with the improvements in picture
quality, the demand for more realistic sound production has also grown.
Virtual sound technologies*2 realized by Sony
through developments of various audio devices are adapted into the "S-FORCE
3D Sound Library" middleware. By simply playing back a game title with
this middleware on a PlayStation 2, three-dimensional sound image movement
and positions that vividly portrait the movements of a character can
be reproduced through 2-channel front speakers such as stereo televisions.
With capability of reproducing the three-dimensional sound as if the
speaker was just beside or behind, this middleware generates a potential
for new game entertainment with more realistic representation and dynamic
story development in unification of sound and graphics.
Sony plans to supply the 3D sound middleware "S-FORCE
3D Sound Library" to game developers/publishers*3
from April 2001.
In autumn 2001, KONAMI CORPORATION plans to release the PlayStation
2 title, "Silent Hill 2" produced by KCE Tokyo, Inc., featuring
this middleware for the first time. They are currently planning to showcase
this new title at the Tokyo Game Show 2001 Spring starting from March
