UK audio compression technology used in new Samsung Bluetooth stereo headset

Cambridge based CSR has announced that its high fidelity audio compression technology has been selected for use in the new Samsung HS3000 Bluetooth Stereo headset.

The firm's aptX technology uses advanced adaptive differential pulse code modulation (adpcm) principles to use the entire 10 to 22kHz high fidelity audio frequency range within the bandwidth of Bluetooth transmission standards. The firm claims it delivers 'unprecedented' audio reproduction within the 92dB dynamic range.

The aptX audio codec is designed to enable source material to be delivered transparently over the Bluetooth link, whether it is stored uncompressed on the source device or uses an alternative compression format such as mp3, AAC or FLAC.

"The HS3000 is Samsung's first aptX enabled consumer audio product and follows our recently announced partnership," said Anthony Murray, senior vp of CSR's Audio and Consumer business unit. "This is the latest milestone along the road to widespread adoption of aptX technology as major consumer electronics manufacturers around the world embrace it as the must have feature to enable high quality music for their wireless audio products."
