Acoustic Technologies SoundClear Software Extends eXpressDSP Compliance from Texas Instruments with the TMS320C55x DSP Generation.Business Editors/High-Tech Writers MESA, Ariz.--(BUSINESS WIRE)--May 19, 2004 Acoustic Technologies, a leading developer of high-quality full-duplex communication software for cellular handsets, announces that its SoundClear(R) Integrated Echo Cancellation The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. & Noise Cancellation (1) The elimination of unwanted signals in an electronic circuit. See noise and dynamic noise reduction. (2) The elimination of unwanted noise in the environment using noise cancelling headphones. DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive software has been certified eXpressDSP(TM) compliant by Texas Instruments See TI. (company) Texas Instruments - (TI) A US electronics company. A TI engineer, Jack Kilby invented the integrated circuit in 1958. Three TI employees left the company in 1982 to start Compaq. for the C55x(TM) DSP generation. TI's eXpressDSP compliance ensures compatibility of algorithms and ease of integration into customer applications using TI's C55x DSPs and chipsets for mobile devices. SoundClear enables natural bi-directional conversation with dramatically improved sound quality for wireless telephony telephony without wires, usually employing electric waves of high frequency emitted from an oscillator or generator, as in wireless telegraphy. A telephone transmitter causes fluctuations in these waves, it being the fluctuations only which affect the receiver. See also: Wireless applications. Texas Instrument's TMS TMS Transcranial Magnetic Stimulation (alternative medicine for depression) TMS Test Match Special (sports - cricket) TMS Texas Motor Speedway TMS Transportation Management System TMS Toyota Motor Sales 320C5000(TM) DSP platform, consisting of TMS320C54x(TM) and C55x DSPs, is ideal for consumer electronics applications such as mobile phones. SoundClear software was previously certified with C54x DSP eXpressDSP compliance. This announcement extends compliance to the C55x DSP. This compliance is especially helpful for applications such as 3G mobile phones that use TI's OMAP OMAP Office of Medical Assistance Programs (Oregon Department of Human Services) OMAP Open Multimedia Applications Platform (Texas Instruments semiconductor operating system) (TM) processors, which integrate a C55x DSP core with an ARM(TM) processor onto a single chip. "Extending SoundClear software's eXpressDSP compliance to all TMS320C5000 platform members gives our customers confidence that our algorithms are easy to integrate into TI DSP-based applications that demand improved sound quality," said Greg Eslinger Greg Eslinger (born April 23, 1983) is a center for the Denver Broncos. He played college football for the Minnesota Golden Gophers and was a four-year starter. As a senior, he was awarded the Outland Trophy, which is given to college football's best interior lineman, as well as , general manager, Software Solutions Group at Acoustic Technologies. "Integrated speakerphone capability is a key component in next-generation mobile phones, and there is tremendous demand for improvements in both performance and sound quality. SoundClear software is essential for enabling high-quality 3G video conferencing See videoconferencing. (communications) video conferencing - A discussion between two or more groups of people who are in different places but can see and hear each other using electronic communications. . We are excited to work with Texas Instruments to enable customers a smooth and rapid integration process for their handset designs." The eXpressDSP compliance program ensures algorithms are written according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the TMS320 DSP Algorithm Standard(TM), a set of coding conventions Coding conventions are rules that computer programmers follow to ensure that their source code is easy to read and maintain. Software source code is plain ASCII text. Coding conventions are important only to the human maintainers and peer reviewers of a software project. and application programming interfaces (APIs). This allows algorithm creators to "wrap" the code for system-ready use allowing for interoperability between algorithms. Instead of re-engineering algorithms for each different system, algorithms are written once and easily reused by integrators. Customers who use eXpressDSP compliant algorithms gain accelerated time to market, improved ease of use, minimal algorithm configuration time, and an additional level of comfort knowing that the product has passed compliance testing for interoperability. "The TI Third Party Program is designed to offer time-to-market advantages, lower development costs and accelerate development efforts for developers who build innovative products and applications on TI DSPs," said Marc Wallace, worldwide DSP third party manager, TI. "We are excited to extend the SoundClear eXpressDSP compliance offering to the C55x DSPs. Acoustic's SoundClear Integrated Echo Cancellation & Noise Reduction DSP software provides customers with improved sound quality for telephony applications. We look forward to continuing working with Acoustic in the future on upcoming technologies." The SoundClear software product is a combination of acoustic echo cancellation, noise reduction, and sound enhancement with sophisticated full-duplex control, optimized for mobile handsets. High-quality voice is achieved through a combination of patented techniques including sophisticated full-duplex control, enhanced nonlinear processing, sub-band processing and adaptive filtering. Annoying echoes are cancelled, background noise is reduced, and speech intelligibility Noun 1. speech intelligibility - the intelligibility of speech (usually measured in the presence of noise or distortion) intelligibility - the quality of language that is comprehensible is enhanced. The SoundClear system adapts quickly to changing environments and enables natural communication flow, just like a face-to-face conversation.
