HSINCHU, Taiwan – December 15, 2023 – Realtek Semiconductor Corporation (Taiwan Stock Exchange: 2379.TW), a world leading network and multimedia IC provider, today announced that its ALC5575 Automotive AI Audio DSP with Embedded Neural Processing Unit (NPU) has received an Innovative Product Award 2023 from the Hsinchu Science Park Administration in Taiwan.

Realtek ALC5575 Final

Realtek’s Automotive AI Audio DSP brings advanced AI audio technology into the In-Vehicle-Infotainment (IVI) as well as In-Car Communication (ICC) systems, providing driver and passengers with a high-fidelity audio experience and the best in-vehicle communication between occupants. Realtek’s in-house NPU leads the AI field with significant breakthroughs in AI bidirectional noise suppression technology and audio quality.

The ALC5575 provides excellent IVI system voice quality for call mode and multiple sound effects in music mode, as well as an ICC system whereby a driver can chat with passengers in the car while keeping his or her eyes on the road. The enhanced computing power brings more audio features to the IVI and ICC systems through Over-the-Air (OTA) channels.

Realtek’s patented technology, along with many years of accumulated audio product development and experience, has resulted in an ideal combination of hardware and AI audio algorithms that can be applied to automotive audio. It can also be extended for applications in commercial products such as audio video conference systems, high-end audio systems, and other fields.

Yee-Wei Huang, Realtek's Vice President and Spokesman said, “Our Automotive AI Audio DSP provides driver and passengers with the best audio quality in call and music,enabling IVI systems to enter the AI era. The bidirectional noise reduction feature brings a relaxing user experience for both drivers and passengers."
