CSR adds embedded DSP virtual surround sound technology to BlueCore5-multimedia

CSR has expanded its portfolio of third-party software for its BlueCore5-Multimedia
platform. Phitek's V3D and LFX technologies allow wireless headset manufacturers to combine leading Bluetooth technology with high quality virtual surround sound and psychoacoustic bass enhancement. CSR's choice to port Phitek's advanced software to BlueCore5-Multimedia provides CSR's customers with access to optimum performance for wireless headset applications, enabling manufacturers to develop quality Bluetooth headsets.

Phitek's V3D technology represents the advanced, configurable and complete set of virtual surround sound algorithms. V3D employs patented reverberation techniques coupled with an HRTF processing engine yielding a powerful configuration. Capable of generating a virtual surround sound experience, V3D not only creates the illusion of multi-speakers through headphones, but also synthesizes additional virtual surround sound channels. Phitek's LFX solution creates the psychoacoustic perception of missing fundamentals for the listener, which improves the apparent bass response of any speaker system.

Anthony Murray, senior vice president of CSR's wireless audio strategic business unit, said, "CSR is committed to providing its customers with the very latest and most advanced technologies on the market. The BlueCore5-Multimedia platform enables CSR to work with the world's leading third-party software vendors in order to bring to market the most complete wireless solutions. Headset manufacturers are assured that when using CSR and Phitek technology that their devices will achieve one of the highest levels of usability and sound quality."

Mark Donaldson, CEO, Phitek, stated, "Consumers now demand high quality voice communication, which forces wireless headset manufacturers to implement the best technology on the market. Through comprehensive understanding of modern control theory and acoustics, Phitek has been able to bring two leading solutions to market. Partnering those with CSR's industry leading Bluetooth silicon provides headset manufacturers with the most optimized and sophisticated solution on the market."
