TrueWireless Stereo

CSR has unveiled the TrueWireless Stereo, a new software development kit (SDK) for high-end Bluetooth stereo headphones and speakers. Based on CSR's BlueCore5-Multimedia platform, TrueWireless Stereo allows manufacturers to quickly bring high quality and innovative Bluetooth products for stereo headsets and speakers to market.

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 synchronization protocol, resulting in truly wireless stereo sound to either a headset or speakers.

"CSR's TrueWireless Stereo software development kit also features the company's proprietary audio enhancement technologies, including Clear Voice Capture 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," said Anthony Murray, senior VP, audio and connectivity strategic business unit, CSR.

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