The CompactSira development kit from Cambridge Silicon Radio now comes with a sample CD of Rappore's Bluetooth host protocol stack, profiles and My Wirefree Network user interface.
SoftMax's technology is based on its proprietary signal separation platform, which uses sophisticated adaptive statistical techniques to separate voice signals from any background noises without the need for training or comprehensive signature databases.
This is achieved by extracting the individual components from the mixture of audio captured by the user's device making it very effective against all types of noise whether they are stationary, such as road noise, or nonstationary like music or other human voices.
SoftMax's technology also eliminates acoustic echo, a big problem in small audio devices.
CSR's BlueCore5-Multimedia platform includes a powerful 64MIPS 24bit DSP.
eXtension partners are provided with development kits and dedicated software tools.
Thanks to the Extension Programme, the most advanced software features and functionality can be easily added to CSR's product offering, boosting both sales and value of Bluetooth-enabled devices for CSR's customers.
Sheldon Gilbert, VP of Business Development, SoftMax, commented: "SoftMax's signal separation technology, providing powerful performance with a very low processing requirement, is a perfect fit for wireless audio applications".
"By working with the Bluetooth market leader, our technology will be integrated in the most advanced Bluetooth solutions on the market, enabling users to be heard in very noisy environments".
Gemma Paris, Software Marketing Manager, CSR, commented: "The integration of SoftMax's technology has set a new benchmark for Bluetooth voice quality and significantly enhances user experience, increasing mobile phone usage".
Paris continued: "CSR's Extension Programme is set to strengthen CSR's portfolio and offer customers cutting-edge technology that is easily integrated into new and existing product lines".
"CSR will continue to expand this programme by working with the most advanced third-party integrated software on the market".
