Anthony Murray, CSR, said:

As the only Bluetooth silicon on the market that can port such third-party software onto its platform, CSR's BlueCore5-Multimedia offers the most dynamic solution available today. The addition of VoiceField onto CSR’s platform only serves to underline CSR’s commitment to provide its customers with Bluetooth devices without compromise…

As CSR's BlueCore5-Multimedia is Bluetooth silicon to combine both integrated DSP and memory, it is in the unique position to be able to provide third party enhancements such as Dynamic Hearing's ATLAS with VoiceField.

VoiceField uses two microphones to capture the speech of the headset user before it is lost amongst competing noise sources. ATLAS with VoiceField is optimised for very low power requirements and very low signal latency on the CSR BlueCore Multimedia platform.

Combined with CSR's BlueCore-Multimedia, Dynamic Hearing's VoiceField multi-microphone technology is the latest addition to their ATLAS solution, which also includes acoustic echo suppression, automatic handsfree volume control and programmable equalisation in 33 frequency bands of both the transmitted and received audio signal. This enhanced solution provides industry-leading clear audio for headset applications.

Dr. Elaine Saunders, CEO of Dynamic Hearing added, "The beauty of CSR's BlueCore5-Multimedia is the flexibility that allows us to swiftly upgrade our software for the benefit of customers. ATLAS with VoiceField provides real added value for customers to quickly and easily enrich the experience of headset users."

CSR's BlueCore-Multimedia silicon provides best-in-class signal-to-noise ratio of 95dB and leads the field in power consumption, enabling a battery life of more than 24 hours of music playback. In addition, the radio transmits at +6.5dBm and receives at -90dBm, eliminating interference when listening to music or making a call.
