CSR announces that its BlueCore3-Multimedia silicon is inside the new MOTOROKR S9, Bluetooth stereo headphones. Due for release in the first half of 2007, the high quality headphones utilise CSR's BlueCore3-Multimedia's integrated DSP and Clear Voice Capture technology. With a tiny 7x7mm form factor, BlueCore3-Multimedia has minimum impact on the overall aesthetics of end-user products and allows for exceptionally compact Bluetooth devices.

Weighing barely an ounce, the MOTOROKR S9 features compact 1.3 cm in-ear speakers and achieves up to six hours of playback from a single charge. Compatible with Bluetooth-enabled stereo music phones and MP3 players, the behind-the-head style headphones offer fingertip control of music and voice calls as well as automatic music muting.

CSR's BlueCore3-Multimedia is a single chip Bluetooth radio and baseband IC with 8Mbits of internal Flash memory as well as an on-chip DSP and stereo CODEC. The embedded Kalimba DSP core is an open platform co-processor that supports enhanced audio applications such as echo and noise cancellation. BlueCore3-Multimedia has been designed to reduce the number of external components required which ensures production costs are minimised while also incorporating auto-calibration and use cases to simplify development, type approval and production tests.
