Technology Allows for Affordable and Complete Presentation of Interactive Sound |
| Fremont, CA – October 7, 1998
– (AURL: OTC Bulletin Board) Aureal™ Semiconductor Inc. today announced the
issuance of U.S. Patent Number 5,802,180 for a "Method and Apparatus for Efficient
Presentation of High-Quality, Three-Dimensional Audio, Including Ambient Effects." Aureal’s technical innovations have now earned 19 patents for the company. With more than 39 additional audio patent applications on file, Aureal is committed to its position of industry leadership in providing users with a complete 3D audio experience. The company’s collection of interactive audio patents now covers the measurement of HRTFs (Head Related Transfer Functions), the rendering of HRTFs, and advanced architectures for the implementation of HRTF capabilities. "This patent represents another milestone in Aureal’s effort to develop an efficient low-cost technology to present interactive immersive audio without compromising quality," said Scott Foster, Chief Technical Officer at Aureal. "Essentially, the passive effects of the virtual environment being presented have been rolled into the HRTF rendering itself, rather than being computed separately as is usually done. The result is a first class complete presentation with very little additional cost to environment effects such as partial reflections, occlusions and atmospheric absorption." Aureal’s portfolio of audio technology now provides end-to-end solutions for 3D audio, including measurement, rendering, and future advancement of 3D audio through Aureal’s A3D technology. A3D was initially developed for NASA and is backed by over a decade of psycho-acoustic research and development. About Aureal Aureal builds advanced audio semiconductor and software solutions that increase functionality and features for personal computers and consumer electronics devices. Aureal develops audio processing semiconductor chips and audio boards and also licenses technology designed to define and improve advanced audio standards in the marketplace. For information on Aureal, its products, and its industry leading A3D audio technologies, please call Corporate Communications at 510-252-4582 or visit our Website at www.aureal.com Forward-looking statements in this release are made pursuant to the safe harbor provisions of the Private Securities Litigation Act of 1995.
