CSR will be presenting its TrueWireless Stereo software development kit, which relies on CSR’s BlueCore5 Multimedia Platform, at CES 2009. The kit, which will be announced at CES 2009, employs two Bluetooth devices, one as the master and the other as the slave. The master supports all handling and control functions, which then relays the audio stream to the slave headset. This allows the product to work with any existing A2DP device.
Audio streams from the audio source to the master unit, which relays them to the slave using the company’s proprietary synchronization protocol. Other features include proprietary audio enhancement technologies including Clear Voice Capture for better audio quality through a microphone and clearer audio through the earpiece via noise cancellation. TrueWireless stereo also supports Bluetooth version 2.1 + EDR and Sub-band coding or MP3 audio file formats.
