CSR Enhances BlueCore5-Multimedia with NXP Software LifeVibes

CSR has announced a new third-party software enhancement for its BlueCore5-Multimedia platform. Continuing to build on the strength of CSR’s eXtension Partner Programme, BlueCore5-Multimedia silicon now offers NXP Software’s speech enhancement technology aimed at Bluetooth headsets, in-car hands-free kits and mobile phones. NXP Software’s LifeVibes(TM) Voice engine, which enhances incoming and outgoing speech and suppresses background noise, addresses the acoustic limitations related to both speakers and microphones. NXP Software’s technology offers full duplex communication, greatly improving the quality of voice communication over a Bluetooth connection, and therefore ensuring that users can hear and be heard in noisy environments.

The LifeVibes(TM) Voice engine offers the latest in Acoustic Echo Cancellation (AEC), noise cancellation and voice clarity improvement. Brought together to improve the performance of Bluetooth mono and stereo headsets, the partnership with CSR specifically covers NXP Software’s solutions for 2-microphone and 1-microphone noise reduction, AEC, intelligibility improvements and far-end noise reduction. Proven in numerous devices, the LifeVibes(TM) Voice engine provides a robust, mature solution, enabling device manufacturers to meet end-user quality expectations. Users can talk and listen comfortably in even the noisiest of environments, such as city streets or train stations. The software is pre-integrated for fast time-to-market and is also highly optimised, with minimal processing and power requirements. Thus, it delivers exceptional performance on the smallest of devices without compromising battery life.

Due to the high-performance on-chip DSP, CSR’s Multimedia platform is the only Bluetooth platform available which can support such third party audio enhancement software. In addition, BlueCore5-Multimedia offers superior sound quality with a best-in-class signal to noise ratio of -95dB. BlueCore5-Multimedia also leads the industry for power consumption and radio design.

Cees Geel, Managing Director, NXP Software, commented, “Consumer demand for Bluetooth headsets is growing rapidly, putting pressure on device manufacturers to design high-quality products. Joining CSR’s eXtension Partner Programme provides these device manufacturers with a ‘one-stop shop’ for proven, best in class audio enhancement software on one of the world’s most widely used Bluetooth ICs.”
