 CAMBRIDGE, UK: CSR today announced that it is now able to offer multi-microphone configuration for Bluetooth headsets via its partnership with Dynamic Hearing. Available on CSR's BlueCore-Multimedia platform, Dynamic Hearing’s ATLAS software library suite has been expanded to incorporate a multi-microphone option, called VoiceField, bringing an extremely clean transmit signal in headset environments.


As CSR's BlueCore5-Multimedia is the only 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.

Anthony Murray, Senior Vice President of CSR's Wireless Audio Strategic Business Unit 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."

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."
