Business Wire, Feb 15, 1995

BASKING RIDGE, N.J.--(BUSINESS WIRE)--Feb. 15, 1995--AT&T Wednesday introduced innovative new software that brings superior audio quality to multimedia personal computers, television set-top boxes, audio/video conferencing terminals, electronic game devices and other devices that offer hands-free communication.

Called QuiteQuiet(TM) Acoustic Echo Cancellation software, this unique line of high-quality, low-cost software products is platform and standard independent. By loading QuiteQuiet software into their terminals and devices, manufacturers can enhance their products with excellent audio quality previously available only with expensive dedicated audio-video systems.

"The QuiteQuiet technology is quite innovative," said Dick Grote, director of Engineering for the Digital Sight and Sound Division of Silicon Graphics Inc., a leader in visual collaborative computing. "It will be very useful in the improvement of future collaborative work environments."

AT&T Custom Electronic Systems, a strategic business unit, offers a complete line of real-time speech processing software products that can be optimally integrated with a variety of speech coding algorithms and automated voice recognition products. In addition to Acoustic Echo Cancellation software, this AT&T business unit offers QuiteQuiet software that removes ambient background noise from both the transmitted and received voice signals in public and wireless terminals. "With the computing power now available in communication terminals it is possible to complement, in a very significant way, the enhancements to voice quality already being delivered by computers in the network," said Ed Harper, president of AT&T Custom Electronic Services.
