SoundClear ATS5500 provides clearer sound for 3G speakerphones

April 22, 2004

Acoustic Technologies, a developer of high quality communication solutions for voice telephony, announced the immediate availability of its next generation SoundClear ATS5500 software for cellular speakerphones. Based on the success of the first generation SoundClear product for mobile handsets, this enhanced software improves voice clarity, full-duplex operation and speaker volume. The ATS5500 SoundClear cellphone software utilizes the DSP already embedded in the cellular handset to provide crisp, clear speakerphone operation for mobile conferencing, 3G video calling and hands-free operation.

As PDA and Internet functions merge into the cellular handset, integrated speakerphones are essential for simultaneously talking on the phone and accessing data or viewing video. Mobile users and network operators are demanding products that solve the problem of poor speakerphone sound quality in mobile handsets caused by echoes and harsh noise environments. SoundClear software enables natural conversation and simultaneous access to voice, data and video. SoundClear optimizes speech intelligibility in cellular applications with full-duplex control that adaptively monitors, detects and processes incoming voice, echo and noise signal power levels.

"SoundClear ATS5500 software is a highly integrated voice processing system, designed to deliver full-duplex speakerphone performance for cellular phones merging voice, data and video. SoundClear enables natural-flowing speakerphone operation that will help proliferate mobile conferencing into the business environment and will create greater demand for 3G services being offered by operators," said Sam Thomasson, Acoustic Technologies CEO.

The SoundClear ATS5500 software is much more than just an acoustic echo canceller. The system integrates acoustic echo cancellation, noise cancellation, sound enhancement and full-duplex control that work together to provide the SoundClear advantage. Dramatic improvements in sound quality are achieved through a combination of patented techniques.

Optimized for full-duplex operation and improved sound quality in harsh noise environments where handsets are commonly used, key features of the SoundClear software include more than 42dB total echo rejection, no distortion or speech clipping, and dynamic adaptation to changing conditions such as noise, speech levels and delay. The ATS5500 software provides fast convergence to changing conditions, even in the presence of background noise. SoundClear software is configurable for various audio performance demands and system constraints.

The ATS5500 is available for Texas Instrument's C54x and C55x families. The solution is optimized for high voice clarity with efficient use of MIPS and memory. The software is written as fixed-point DSP code and is portable to other commercial or proprietary DSP architectures.
