Acoustic Technologies Expands its Full-Duplex Portfolio with the ATH4200 Fully Integrated Speakerphone IC.Business Editors/High-Tech Writers MESA, Ariz.--(BUSINESS WIRE)--Sept. 20, 2002 Accompanying eXcho(TM) Toolkit Shortens Product Development Cycle and Simplifies System Tuning Process Acoustic Technologies, a leading developer of high quality communication solutions for telephony equipment, today introduced the ATH4200 Full-Duplex speakerphone integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for for improved sound quality in telephony applications. The ATH4200 dramatically improves voice clarity in telephony applications and provides full-duplex speakerphone operation with Acoustic Technologies unique SoundClear(TM) technology and integrated analog functions. Acoustic simplifies the development effort by offering a comprehensive evaluation and tuning toolkit complete with the company's eXcho SW package.

"The ATH4200 is a complete integrated solution supporting full-duplex digital voice processing The computerized handling of voice, which includes voice store and forward, voice response, voice recognition and text to speech technologies. with integrated pre-amps, speaker drivers, and CODECs The following is a list of codecs. Audio codecs Non-compression formats
Optimized for improving sound quality, the ATH4200 includes a 5-band Graphic Equalizer graphic equalizer n. An electronic equalizer that allows one to increase or decrease a fixed set of frequency ranges in an audio system. graphic equalizer See under equalizer. for frequencies within the voice band and separate bass and treble gain controls for enriching sound frequencies outside of the voice band. Patented sound enhancement techniques increase audio fullness and presence for richer and clearer speech. Sound enhancement effects in the ATH4200 are tunable to specific applications, casings, and user preferences. Acoustic Technologies SoundClear products combine acoustic 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. , bi-directional noise reduction, sound enhancement, and far-side anomaly reduction with sophisticated monitoring and control techniques to enable full-duplex speech and improved voice clarity. SoundClear optimizes 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 with full-duplex control that adaptively monitors, detects and processes incoming voice, echo, and noise signal power levels. Applications such as desktop speakerphones, SOHO Soho (sōhō`, sə–), district of Westminster, London, England, known for its continental restaurants. Once a fashionable quarter, it became popular among writers and artists in the 19th cent. phones, conference room speakerphones, PBX (Private Branch eXchange) An inhouse telephone switching system that interconnects telephone extensions to each other as well as to the outside telephone network (PSTN). and VoIP phones will benefit from the unique SoundClear advantage included in the Acoustic Technologies family of voice processing products. The ATH4200 is complimented by a comprehensive evaluation and tuning kit allowing users quick setup and evaluation of key performance features in the ATH4200 device. The eXcho tool makes system tuning easy and in-system debug To correct a problem in hardware or software. Debugging software means locating the errors in the source code (the program logic). Debugging hardware means finding errors in the circuit design (logical circuits) or in the physical interconnections of the circuits. simplifies design, prototyping, test, and field analysis. The result is a dramatic improvement in sound quality, full-duplex speakerphone operation, and a reduction in design and development cycle time. The ATH4200 is available for immediate sampling in a 48-pin LQFP See QFP. package. Evaluation and tuning kits for the ATH4200 are also available.
