Superb audio quality that will drive upgrades - with CVC v5.0

CVC® or Clear Voice Capture, is CSR's own DSP software technology for enhancing audio quality on wireless products. A modular suite of algorithms includes acoustic echo cancellation and noise suppression that can be applied in a granular fashion and tuned to suit the application. CSR has been shipping noise and echo suppressing versions of CVC for many years with ROM-based headset designs. An enhanced fifth-generation algorithm is provided for BC5 Multimedia, BC6140 and BC6150:

• BC6140 provides single-microphone audio enhancement algorithm offering up to 18dB of stationary noise reduction.

• BC6150 provides a dual-microphone audio enhancement algorithm offering more than 30dB of dynamic noise reduction.

Applications

CSR offers CVC as integrated elements of development tools and ready-to-use solutions for common Bluetooth applications. Examples include:

The BC6100 range provides a mid-level headset product range and two solutions that introduce active audio quality enhancement.	Groundbreaking BlueTunes ROM slashes the cost of building advanced Bluetooth® stereo wireless headphones for music and audio applications.	RoadRunner Plug'n'Talk is a ready to apply Bluetooth design for automotive applications - with echo cancellation and noise suppression algorithms optimised for the automobile cabin.
