Full-Duplex VoIP Speakerphone Controller Introduced by Acoustic Technologies.Business Editors/High-Tech Writers MESA, Ariz.--(BUSINESS WIRE)--June 10, 2004 Acoustic Technologies, a leading developer of high-quality communication solutions for telephony equipment, today introduced the ATH3003 VoIP 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 VoIP applications. The ATH3003 provides full-duplex speakerphone operation with Acoustic Technologies' unique SoundClear(R) technology, dramatically improving voice quality in VoIP telephony applications. Signal integrity and superior sound quality are achieved through the SoundClear suite of technology and full-duplex control that dynamically monitors, detects and processes incoming voice, echo, and noise signal power levels. The unique 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. technology is robust to VoIP delay and network imperfections. "The ATH3003 provides audio signal processing Audio signal processing, sometimes referred to as audio processing, is the processing of a representation of auditory signals, or sound. The representation can be digital or analog. between the digital VoIP to analog user interface domains, bringing our unique SoundClear technology for improved voice quality to VoIP applications," said Sam Thomasson, Acoustic Technologies chief executive officer. "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 tier-one VoIP phone See IP phone and softphone. vendors we are working with, the ATH3003 device provides high-quality full-duplex speakerphone performance with seamless interface to popular VoIP controllers." Features of the ATH3003 include 42dB acoustic echo cancellation, 30dB network echo cancellation, up to 12dB noise reduction, graphic equalizers, and sound enhancement. There is an integrated analog CODEC, microphone preamp, and speaker driver for interface to microphone and speaker. Also, the digital PCM (1) See phase change memory. (2) (Plug Compatible Manufacturer) An organization that makes a computer or electronic device that is compatible with an existing machine. interface provides an easy interface to VoIP controllers compatible with Ethernet, Wi-Fi, or USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. , supporting both time-shared and dedicated PCM. To improve the sound quality and simplify phone system design, the device includes dual 10-band Graphic Equalizers, comfort noise, and DTMF (Dual-Tone MultiFrequency) The type of audio signals that are generated when you press the buttons on a touch-tone telephone. See also DMTF. DTMF - Dual Tone Multi Frequency generation. Handset and speakerphone call management and programmable ringer tone generation round out the sophisticated set of features on the ATH3003. The SoundClear-enabled ATH3003 is available for immediate sampling in a 48-pin LQFP See QFP. package. The ATH3003 is tunable to specific VoIP phone casings and user preferences. Acoustic Technologies SoundClear products combine patented acoustic echo cancellation, 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. The full-duplex operation provides rich, clear, enhanced sound with no clipping or distortion. SoundClear optimizes speech intelligibility with full-duplex control that adaptively monitors, detects and processes incoming voice, echo, and noise signal power levels.
