CSR today announced CSR Harmony, an intelligent connectivity software framework, that enables a seamless wireless experience for Windows®-based PCs, integrating Bluetooth v4.0 + High Speed, Wi-Fi and GPS functionality. With CSR Harmony, users now have unparalleled wireless connectivity options including health and fitness, high-end audio and ultra-low power accessories. Users can synchronise data between their PC and mobile devices in a fraction of the time using the new Bluetooth High Speed protocol. Bluetooth v4.0 (also known as Bluetooth low energy) extends the battery life of Bluetooth accessories such as mice and keyboards from months to years.

Combined with CSR's market-leading Bluetooth audio platforms, CSR Harmony provides a premium audio experience, supporting wide-band mono audio and also the new apt-X lossless stereo codec. The apt-X codec delivers CD-quality audio over the Bluetooth link with virtually no latency. Lip-sync issues common with normal Bluetooth stereo headsets are a thing of the past. In addition to high-end audio, CSR Harmony enables the Bluetooth and Bluetooth low energy ecosphere of devices including a new range of wireless connected low energy health and fitness products such as heart rate monitors and pedometers.

?PC users now expect a broad range of wireless functionality to be integrated in the PC as standard,? commented Eric Neilson, Senior Product Marketing Manager for PCs in CSR's Audio and Consumer Business Unit. ?I'm very excited to say the CSR Harmony-enabled wireless platform provides a wireless solution that enables the user to easily and intelligently manage their ever-growing collection of Bluetooth, Wi-Fi and GPS devices through their PC. As PCs begin to interact with the low energy devices, sensors, and alternate radios that proliferate around the home, office and around the world, CSR Harmony will open up a vast range of new possibilities offered by Bluetooth low energy and Bluetooth High Speed that is limited only by the creativity of consumer electronics designers. CSR Harmony also provides an excellent route through our audio enhancements,? continued Neilson, ?for users to enjoy games and music on their PCs the way they were meant to be heard, but without the need for wires.?

Anthony Murray, the Senior Vice President of CSR's Audio and Consumer Business Unit also commented on the importance of providing the best wireless connectivity for PC users, ?The launch of our CSR Harmony software platform is an important milestone in CSR's PC strategy and will improve the user experience for the growing number of wireless and location aware use cases around the PC.?

CSR Harmony enables PC Bluetooth profiles, and the new Bluetooth low energy profiles designed for health and fitness, mice and keyboards, and other PC accessories.
