CSR wireless audio platform chosen by LG Electronics for ultra-slim headset and new car speakerphone design

BlueCore and CVC 5.0 provide market-leading wireless audio to enhance the end-user experience

Cambridge, UK - May 20, 2010 - CSR (LSE: CSR) today announced that LG Electronics's new HBM585 ultra-thin Bluetooth mono headset and HFB320 hands-free car kit  both utilise CSR's audio platform incorporating Bluetooth wireless connectivity and fifth-generation CVC noise and echo reduction.

"The HBM585 and HFB320 demonstrate the high level of innovation people have come to expect from LG," commented Harris Ahn, General Manager of LG Mobile Application Products Group. "Our close collaboration with CSR has allowed us to achieve outstanding audio performance and important user features for each product. CSR's support and flexibility has helped us bring the latest features and enhancements in these products to market quickly."

CSR's audio platform is a versatile, single-chip solution comprising an on-chip DSP core, stereo CODEC, audio algorithms and BlueCore Bluetooth functionality. CVC is a manufacturer tuneable suite of low power audio algorithms that run on CSR's power efficient DSP to deliver superb audio performance. It provides far-end and near-end noise suppression, echo cancellation, speech intelligibility enhancements, automatic volume control and concealment of packet loss and bit errors.

LG's HBM585 and HFB320 products offer the latest user-friendly features launched into the audio and connectivity sector by CSR. These include proximity pairing for the easiest possible Bluetooth pairing experience, audio prompts to guide the user with natural language audio updates, and advanced multipoint to support connection to two handsets. The near-end noise suppression in CVC 5.0 filters out noise received from the caller at the other end of the link, and allows the user to receive clearer-quality speech, even if the caller at the other end does not have CSR's noise reduction technology in their own device.

"CSR continues to lead with wireless audio solutions for headsets and hands-free kits that deliver a compelling combination of high performance CVC audio enhancements, best-in-class RF, low power and the latest user-friendly features. All of these features support innovative companies such as LG in realising the best possible headset products." said Anthony Murray, Senior Vice President of CSR's Audio and Consumer Business Unit. "We value the opportunity to work closely with LG to bring our very best wireless audio solutions to market in compelling products for the benefit of end users."

At just 3.8mm the groundbreaking and elegant HBM585 is an ultra-thin headset. Achieving a high quality audio link in such a small profile design is made possible through a combination of CSR's high performance RF and the latest DSP-based CVC audio enhancements, which deliver superb audio performance at very low power.

The LG HFB320 is a Bluetooth car speakerphone which benefits from the very latest hands-free echo cancellation upgrade to CSR's fifth generation CVC. With this upgrade CSR's product addresses "residual" echo due to speaker distortion. This allows higher audio volumes to be used without perceptible echo in car speakerphones. CSR worked closely with LG throughout the HFB320's design to achieve this new level of cost and performance.
