Qualcomm brings noise cancelling technology

QualcommSemiconductor giant Qualcomm Technologies announced active noise cancelling (ANC) technology onto its CSR8675 product platform.

The world’s first Bluetooth audio system-on-chip (SoC) to integrate advanced audio solution reduces the complexity and cost of adding active noise cancelling to headphones by eliminating the need for a separate ANC chip. Manufacturers can now quickly deliver premium audio experiences in much smaller form factor designs.

Qualcomm said CSR8675 is an integrated Flash platform with embedded 120Mhz 24-bit DSP and supports Qualcomm aptX and Qualcomm aptX HD audio technologies for consistent, high-quality audio streaming over Bluetooth.

“Users want to enjoy a superb audio experience in any environment, without sacrificing quality when they listen to their music, videos and games,” said Anthony Murray, senior vice president and general manager, IoT, Qualcomm Technologies International.

“We’ve added the CSR8675 with integrated ANC to Active Noise Cancelling Bluetooth headphones to offer a high quality audio experience,” said Tom Li, executive vice president of business development, Fujikon Industrial.

Fujikon Industrial is utilizing the ANC technology integrated onto the CSR8675 device. Its headphone features an extended playtime of approximately 12 hours and noise cancelling performance of up to -23dB.

Qualcomm TrueWireless Stereo Headset Reference Design

Meanwhile, Qualcomm Technologies International has introduced the Qualcomm TrueWireless Stereo Headset Reference Design to meet growing demand in the headset and hearables markets for much smaller form factor.

Qualcomm TrueWireless Stereo technology eliminates the need for wires – not only between the media source and stereo headset, but also between left and right earbuds.

Qualcomm TrueWireless Stereo Headset Reference Design is based on the CSRA63120 audio ROM device which supports stereo Bluetooth headsets to function completely wire free and is ideal for manufacturers who wish to make wireless earbuds, without deploying enormous design, validation and testing resources or acquiring radio frequency design expertise.
