CSR will use software from nFore Technology to provide noise and echo cancellation and music enhancements for in-car Bluetooth solutions. nFore participates in CSR’s eXtension Partner Programme, an open DSP developers’ program that channels third-party software enhancements to CSR’s BlueCore5-Multimedia platform.
nFore’s technology includes adaptive acoustic echo cancellation (AEC), active noise cancellation, stereo sound enhancements, omnidirectional microphones, a bass boost solution for headphones, and a solution for avoiding voice clipping during a call.
CSR also has added an echo cancellation feature to RoadRunner Plug-n-Talk, its reference design for low-cost Bluetooth hands-free kits. The echo cancellation feature provides enhanced sound quality in automotive cabins. The reference design is based on CSR’s BlueCore3-Multimedia, which includes an on-chip DSP and CODEC, and it includes CSR’s BlueLab software, a configuration tool that offers full access to the source code.
