Jack Chen, nFore, said:

The flexibility of CSR's BlueCore5-Multimedia silicon means that we are able to bring our speech and audio software to enrich the experience of users in the automotive market…

…nFore's participation in the eXtension Partner Programme allows CSR’s automotive customers a generous set of acoustic technologies

nFore’s adaptive AEC (Acoustic Echo Cancellation) removes echo quickly at the start of a call, as well as a full-duplex solution to avoid voice clipping during the call. Two omni-directional microphone solution and active noise cancellation technology further reduces unwanted noise by more than 90%.

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 utilises unique auditory characteristics to reproduce low frequencies.

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

BlueCore5-Multimedia also leads the industry for power consumption and radio design. The radio transmits at +6.5dBm and receives at -90dBm which eliminates interference when listening to music or taking a call. When used in stereo headset applications, BlueCore5-Multimedia enables industry-leading battery life of more than 24 hours of music playback.
