– CSR, a leading global authority in personal wireless communications and Bluetooth technology, today announced the launch of the BC6145, the most advanced Bluetooth audio platform for single-microphone mono headsets, speakerphones, automotive accessories, and popular wireless audio accessories. The BC6145 is the first ROM-based mono device that supports new consumer-centric features including HD (High Definition) voice calling, A2DP music streaming, and enhanced voice clarity.

The BC6145 also supports advanced features such as bidirectional noise cancellation and ultra-low-power wind noise reduction (WNR) that significantly enhance the user experience for affordable Bluetooth mono headsets. In particular, the ready-to-use BC6145 further solidifies CSR's technological superiority and leadership in the popular Bluetooth mono headset market. Major mobile phone and Bluetooth accessory manufacturers are already designing next-generation headsets using the BC6145 audio platform.

Voice Quality Enhancement

As part of the HD voice deployment currently being pursued by mobile carriers, the BC6145 can significantly improve calling quality across wireless accessories. Multiple carriers, including France Telecom, 3UK, and Orange, have already deployed HD voice services. The BC6145 provides manufacturers with the fastest business opportunity to establish themselves in the market as an affordable mono headset that includes the mSBC codec and optimal user experience.

Music Transmission to Mono Headsets

With the widespread adoption of A2DP, which provides music streaming to media players and mobile phones, most consumers can use the BC6145's capability to play music from high-quality A2DP audio sources. This powerful and new feature used in mono headsets is useful for users who want to listen to music in mono mode through headset earpieces or speakerphones. Additionally, the A2DP music streaming feature available even in affordable mono headsets provides manufacturers with very important functional differentiation.

Voice Clarity Enhancement

By providing improved voice clarity, the BC6145 enables headset users to have cleaner and clearer conversations even in noisy environments. This feature reduces listener fatigue that can accumulate during long conversations and enables safe handling of dual tasks such as talking on the phone while driving. Additionally, BC6145-based headsets feature bidirectional noise cancellation that reduces noise in received audio. Compared to typical noise reduction transmission in other silicon products that only provides benefits to the caller, BC6145-based headsets offer the advantage of providing the same user experience to the listener as well.

Furthermore, the ultra-low-power high-performance wind noise reduction (WNR) algorithm provides BC6145-based headset users with the convenience of being able to have as much conversation as possible even in windy conditions without concern. In particular, since the wind noise reduction feature only operates when wind noise is detected, manufacturers can optimize the call
