Acoustic Technologies' SoundClear Software Earns eXpressDSP Compliance from Texas Instruments.Business Editors/High-Tech Writers MESA, Ariz.--(BUSINESS WIRE)--April 23, 2002 Acoustic Technologies, a leading developer of high quality full-duplex communication software for cellular handsets, Tuesday announced that its ATS5000 SoundClear(TM) 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 Reduction 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. . TI's eXpressDSP compliance ensures compatibility of algorithms and ease of integration into customer applications using TI'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 320C54x(TM) family of programmable 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. "By achieving eXpressDSP compliance for SoundClear, it allows customers to be confident that our algorithms are easy to integrate into TI DSP-based applications demanding improved sound quality," said Ed Rocha, general manager, Software Solutions Group at Acoustic Technologies. "Speakerphones are becoming pervasive in advanced communication devices on next generation wireless networks where there is high expectation and tremendous demand for improved performance and sound quality. We are excited to work with Texas Instruments to enable customers a smooth and rapid integration process for new handset designs and retrofit ret·ro·fit v. ret·ro·fit·ted or ret·ro·fit, ret·ro·fit·ting, ret·ro·fits v.tr. 1. To provide (a jet, automobile, computer, or factory, for example) with parts, devices, or equipment not in projects." 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 through a wide selection of value added Value Added The enhancement a company gives its product or service before offering the product to customers. Notes: This can either increase the products price or value. tools in a unified environment, 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 accelerated development efforts for developers who choose to build innovative products and applications around TI DSPs," said Ray Wagstaffe, Worldwide DSP third party manager, TI. "We are excited to add Acoustic to our list of technology partners. Its SoundClear(TM) Integrated Echo Cancellation & Noise Reduction DSP software provides customers with improved sound quality for telephony applications. We look forward to working with Acoustic in the future on new technologies." The SoundClear ATS5000 product is a combination of acoustic echo cancellation, noise reduction, and network echo cancellation with sophisticated full-duplex control, optimized for mobile handsets. High quality sound is achieved through a combination of patented techniques including sophisticated full-duplex control, enhanced non-linear processing, sub-band processing and adaptive filtering An adaptive filter is a filter that self-adjusts its transfer function according to an optimizing algorithm. Because of the complexity of the optimizing algorithms, most adaptive filters are digital filters that perform digital signal processing and adapt their . This integrated solution provides very fast convergence, long echo tail rejection, and dynamic adaptation to changing conditions such as noise, speech levels, or delay. 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 conversation flow, just like a face-to-face conversation.
