  ADVANCED GRAVIS ADDS THE NEXT DIMENSION TO COMPUTER SOUND WITH
      ULTRASOUND 3D(tm) FEATURING FOCAL POINT(tm) TECHNOLOGY

Advanced Gravis is pleased to announce that it has entered into a
license agreement to produce and sell a software product called
Focal Point 3D Audio for the IBM PC.  Under the license agreement
Gravis has acquired an exclusive license to the product for one
year, subject to the payment by Gravis of minimum royalties, and
non-exclusive license for a further 4 years.

Focal Point 3D audio is the basis for Gravis UltraSound 3D for the
IBM PC, and is the next step in the evolution of the Gravis
UltraSound card.  It places the computer user in the middle of an
audio environment for immersive virtual reality audio.  Gravis
UltraSound 3D will be unveiled today at the Consumer Electronics
Show in Las Vegas, Nevada.

For the first time outside virtual reality labs and at an
affordable consumer pricepoint, sound effects, music, even simple
clicks of a mouse can be placed in an audio space that surrounds
the user like a sphere.  Utilizing Focal Point technology,
UltraSound 3D processes the audio signal through a technique called
convolution, where new right and left binaural audio signals are
generated that create a wraparound sound effect to the human ear. 
The sound signal is actually a stereo signal shaped electronically
to make the listener hear the sound as three-dimensional and in the
correct location -- a psychoacoustic effect that can be manipulated
in real time.

"Game Players - particularly jet fighter enthusiasts - will be the
first to embrace Gravis UltraSound 3D," said Grant Russell,
president of Advanced Gravis.  "As a fighter zooms past, the sound
will follow the jet from behind towards the front.  Sound can even
be placed above or below the player."

"there are many other significant applications," Russle continued. 
"Entertainment multimedia such as the new music CD-ROMs can now
deliver a much more interactive concert environment.  Business
applications can use 3D audio to enhance presentations or even help
visually impaired users navigate complex spreadsheet.

Advanced 'Gravis hopes to begin shipping Gravis UltraSound 3D by
the of the first quarter of 1993 for $249 US complete with 512K of
memory.  Gravis Ultra?Sound 3D will ship with utilities for
creating and manipulating 3D audio.  Independent software
developers will be required to create new sound tracks for their
products to provide UltraSound users with 3D audio.

The Gravis UltraSound card, introduced in October 1992, offers 16-
bit, 32-voice wave table synthesis and CD quality sound
reproduction and recording capability.  UltraSound is compatible
with Sound Blaster(tm) and Ad Lib(r) and supports Microsoft Windows
3.1 Multimedia Extensions.

Advanced Gravis is leading designer and manufacturer of high -
quality entertainment devices for personal computers, including
joysticks, PC GamePads, MouseSticks, and UltraSound.
