Acoustic Technologies Extends Availability of SoundClear Full-Duplex Speakerphone Software to StarCore Processor Cores

Acoustic Technologies Joins StarCore Alliance Program

MESA, Ariz.—(BUSINESS WIRE)—Aug. 24, 2004— Acoustic Technologies, a leading developer of high-quality communication solutions for voice telephony, today announced the availability of SoundClear(R) ATS5500 software for the StarCore(TM) SC1000 family of processor cores. The ATS5500 SoundClear speakerphone software integrates echo cancellation, sound enhancement, and noise cancellation to enable natural bi-directional conversation with crisp, clear speakerphone operation. SoundClear software is ideal for applications using SC1000-family processor cores and subsystems such as mobile handsets, mobile conferencing devices, video conferencing equipment, and other hands-free telephony devices. As a StarCore Alliance member, Acoustic Technologies will provide SoundClear software for StarCore licensees to improve voice quality and help get their products to market faster.

"SoundClear software can improve the quality and performance of voice-based applications making StarCore-based chips an even more attractive option for customers designing mobile handsets and other hands-free consumer products. StarCore customers will benefit from the SoundClear software's high level of full-duplex speakerphone performance, enabling natural two-way communication, just like a face-to-face conversation," said Sam Thomasson, Acoustic Technologies' chief executive officer. "With StarCore's tier 1 customer base and outstanding efficiency of their processors, we are excited to join the StarCore Alliance Program, helping bring StarCore-enabled products to market faster."

According to Gartner Dataquest's User Survey for Personal Wireless, dated June 24, 2004, hands-free capability is the highest-ranked new feature that motivates the purchase of a new mobile handset in the next 12 months. Integrated full-duplex speakerphone capability is a key component in next-generation 3G mobile phones to enable simultaneous access to voice and data for videoconferencing and hands-free operation. SoundClear software for cellular handsets offers high-quality full-duplex hands-free operation, noise reduction, and improved speech intelligibility with graphic equalizers, enabling natural conversation flow. The software is optimized to provide high-quality voice with minimal MIPS and memory usage.

"We are very pleased to welcome Acoustic Technologies as a valued member of the StarCore Alliance Program. The combination of the proven ATS5500 SoundClear software and StarCore's superior code density and efficiency provides a compelling hands-free solution to our customers," said Philippe Bettler, manager of strategic alliances at StarCore.

StarCore's SC1000 family is licensable intellectual property that provides system-on-chip (SoC) designers with the right combination of DSP performance and related subsystem capabilities. StarCore products are used in communications systems, wireless phones and other consumer electronics products. SoundClear software is available for StarCore SC1000-family cores.
