CSR Integrates CVC and Raises the Bar for Voice Quality in Bluetooth Headsets.CAMBRIDGE, England -- CSR plc (LSE LSE - Language Sensitive Editor :CSR (1) (Customer Service Representative) A person who handles a customer's request regarding a bill, account changes or service or merchandise ordered.

By using BlueLab 3.2, software engineers can now easily design a mono or stereo headset or a car handsfree kit containing CVC, which enhances voice quality when making calls. CSR acquired CVC technology via its purchase of Clarity Technologies in March 2005. CVC technology features a noise suppression algorithm which extracts the user's voice from the extraneous noise of the environment. The advanced echo suppression system also removes all unwanted echoes so that headset designers can position the microphone close to a speaker (even a powerful one) in order to satisfy consumer demand for compact and attractive products. A microphone can now also be reliably integrated into a stereo headset earpiece and be able to offer high voice quality while giving no outward indication of its presence. CSR has addressed the cost and current consumption issues linked to the implementation of echo and noise suppression technologies through both its Bluecore3-Multimedia (BC3-MM) silicon and CVC. The efficient, in-built 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 removes the need for designers to purchase an expensive external processor for audio analysis. Compared to a general purpose RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. based processor, the DSP is also more efficient in audio processing. This reduces the power consumption to a level similar to today's generation of headsets without integrated echo and noise suppression. Jim Wargnier, technical manager, CSR Detroit commented "The DSP architecture in BC3-MM allows us to implement CVC, the world's leading voice enhancement software for Bluetooth devices, in the most efficient way." Wargnier continued, "The power consumption is half that of a RISC based processor and integrating the DSP also greatly reduces costs". Luke D'Arcy, product marketing manager, CSR added, "Mainstream consumers are demanding better voice quality from Bluetooth headsets. BlueLab 3.2 allows designers to respond by including world class echo and noise suppression. Thanks to the integrated DSP in BlueCore3-Multimedia, this no longer means increasing cost or power consumption excessively. D'Arcy continued, "CVC will enable a whole new generation of high performance Bluetooth headsets, expanding the market to the most discerning users. CSR intends to incorporate CVC into future solutions for mono and stereo headset, allowing designers to achieve world class quality as standard." About CSR CSR plc is the leading global provider of Bluetooth technology and has developed expertise in other single-chip wireless communication standards such as Wi-Fi (IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.11). CSR offers developed hardware/software solutions for Bluetooth based around BlueCore, a fully integrated 2.4 GHz radio, baseband and microcontroller. CSR is now producing its fourth generation BlueCore devices. BlueCore4 supports the Enhanced Data Rate (EDR (Enhanced Data Rate) An acronym occasionally used to reflect an advancement in transmission or transfer speed. For example, Bluetooth 2.0 + EDR provides a dramatic increase in speed over the previous version. See Bluetooth. ) standard which was ratified at the end of 2004. BlueCore4 remains the only EDR silicon to be shipping in volume today. In November 2004 CSR launched UniFi, the first single chip 802.11a/b/g embedded solution specifically targeting the mobile phone and consumer electronics markets. BlueCore features in over 50 per cent of all Bluetooth devices shipped and over 60 per cent of all qualified Bluetooth enabled products and modules listed on the Bluetooth website with industry leaders including Nokia, Dell, Panasonic, Sharp, Motorola, IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) , Apple, NEC (NEC Corporation, Tokyo, www.nec.com, www.necus.com) An electronics conglomerate known in the U.S. for its monitors. In Japan, it had the lion's share of the PC market until the late 1990s (see PC 98). NEC was founded in Tokyo in 1899 as Nippon Electric Company, Ltd. , Toshiba, RIM and Sony using BlueCore devices in their range of Bluetooth products. In March 2005, CSR acquired Clarity Technologies Inc., for its Clear Voice Capture (CVC) technology that enhances the audio performance of any voice-based product or system. Applications for CVC include wireless headsets, handsets and automotive hands free systems. CSR has its headquarters in Cambridge, UK, and offices in Japan, Korea, Taiwan, Denmark, Sweden and both Texas and Detroit in the USA.
