CSR (LSE: CSR) today announced the launch of TrueWireless Stereo, a new software development kit for high-end Bluetooth stereo headphones and speakers. Based on CSR’s popular BlueCore5-Multimedia platform, TrueWireless Stereo allows manufacturers to quickly bring high quality and innovative Bluetooth products for stereo headsets and speakers to market. CSR will be giving demonstrations of TrueWireless Stereo at CES, Las Vegas from 8-11 January 2009.

The development kit is based on the use of two Bluetooth devices, one as the master and the other as the slave. The call handling and control are supported on the master device which then relays the audio stream to the slave headset. This allows the product to work with any existing A2DP device already on the market. Audio is streamed from the audio source to the master unit and is relayed to the slave using CSR’s proprietary synchronisation protocol, resulting in truly wireless stereo sound to either a headset or speakers.

“The TrueWireless Stereo software development kit (SDK) has already attracted interest from a number of CSR’s tier one customers, and it will allow manufacturers to focus on building unique products in the rapidly growing Bluetooth stereo headset and speaker markets,” said Anthony Murray, Senior Vice President, Audio and Connectivity Strategic Business Unit, CSR. “CSR’s TrueWireless Stereo software development kit also features the company’s proprietary audio enhancement technologies, including Clear Voice Capture (CVC) for improved audio quality through a microphone, and clearer audio through the earpiece through noise cancellation. TrueWireless stereo also supports Bluetooth version 2.1 + EDR along with sub-band coding or MP3 audio file formats.

The TrueWireless Stereo SDK is available now on a BlueCore5-Multimedia platform.
