CSR and nFore enhance in-car Bluetooth audio

CSR has added NFore's noise cancellation and other software enhancements to its BlueCore5-Multimedia silicon.

nFore's adaptive AEC (Acoustic Echo Cancellation) technology removes echo quickly at the start of a call and its full-duplex solution avoids voice clipping during the call.

In addition, by using two omni-directional microphones and active noise cancellation technology, nFore's software reduces unwanted noise by more than 90%, providing the user with cleaner music or speech.

nFore brings a number of audio enhancements for improved stereo sound including virtual reality sound and virtual stereo sound to bring sound to life. Also included is PowBass, a bass-boost solution for headphones which utilizes unique auditory characteristics to reproduce low frequencies.

“The flexibility of CSR's BlueCore5-Multimedia silicon means that we are able to use our speech and audio software to enrich the experience of users in the automotive market,” added Jack Chen, Vice President, nFore. “nFore's participation in the eXtension Partner Program allows CSR's automotive customers a generous set of acoustic technologies.”

The software was acquired through CSR's eXtension Partner Programme, an open DSP developers' program for third-party software enhancements to the BlueCore5-Multimedia platform.

Due to a high-performance 24-bit 64 MIPS on-chip DSP, CSR's BlueCore5-Multimedia platform can support a variety of third-party audio enhancement algorithms. BlueCore5-Multimedia provides superior sound quality with a best-in-class -95dB signal-to-noise ratio.
