New Audio Drivers Support Gravis UltraSound

Major Installed Base of Game Developers Can Now Step Up to UltraSound
Quality With Ease

VANCOUVER, British Columbia -- May 24, 1993 -- Software developers have
three new options that incorporate the high quality audio reproduction of
Gravis UltraSound into their programs, thanks to new audio drivers
developed by Advanced Gravis and Rochester, NY-based FORTE Technologies.

The three audio drivers consist of Audio Interface Libraries (AIL) drivers,
DigPak, and MidPak drivers, which allow developers to integrate sound
capabilities into their programs. These drivers are used by a large
percentage of the computer game industry. Advanced Gravis and FORTE have
designed new AIL routines for UltraSound that make it easy for developers
to integrate and use UltraSound's audio features. The new AIL drivers
allow existing FM synthesis games to play in UltraSound's native mode and
utilize Gravis' MIDI patches and digital sound. They also allow developers
to make their new releases UltraSound compatible, allowing for higher
quality sound tracks and sound effects.

Along with the new AIL drivers, Gravis and FORTE have also developed a
standalone driver that uses a Terminate and Stay Resident (TSR) utility
called UltraMID, which allows users to take advantage of UltraSound's more
advanced features. Developers can use this utility to read the UltraSound
card directly, enable digital playback at 8 or 16-bit up to 44.1 kHz
resolution, and utilize all of the card's 32 voices and more realistic
sounding wave table synthesizer.

"This is a significant step toward migrating the standard of computer audio
to the higher fidelity of wave table synthesis," said David Reid, vice
president of marketing for Advanced Gravis. "These drivers offer another
level of support for game developers, and because the DigPak and MidPak
drivers are used by most of the computer gaming industry, we are
optimistic that UltraSound will become the new standard for the
discriminating gamer.

Developers with current AIL drivers may obtain the UltraSound update
through Advanced Gravis' BBS at 604/431-5927. Developers who do not have
the AIL drivers can contact Audio Solution Inc. at 314/567-0267.

In addition to UltraSound, Gravis' 16-bit CD-quality stereo sound cards
featuring wave table synthesis and recording, Advanced Gravis Computer
Technology Ltd. also designs, manufactures and markets high quality
microcomputer input devices, including the Gravis Analog Pro Joystick and
GamePad for the IBM platform, and the MouseStick II and GamePad for
Macintosh.
