WiSA Partners with Realtek to Develop and Launch a 5GHz Multichannel Immersive Audio Module

WiSA’s High-performance Spatial Audio Software to be Integrated into Realtek’s 5GHz IoT Audio Platform

WiSA, LLC, a wholly-owned subsidiary of Summit Wireless Technologies, Inc. (Nasdaq: WISA), a leading provider of immersive, wireless sound technology for smart devices, will integrate WiSA’s multichannel spatial audio capabilities into Realtek’s 5GHz IoT chip feature set. The partnership will culminate in a cost-effective IoT module capable of delivering uncompressed, high-definition spatial audio streams for an unparalled immersive audio experience.

President of Realtek K.Y. Yen said, “Realtek looks for strong industry partners to bring increased functionality to our line of IoT audio and video chips. Spatial audio is a new and exciting market and we are happy to partner with WiSA and the engineers at Summit to bring this new immersive audio experience to our customers’ products.”

Chairman of WiSA, LLC and CEO of Summit Wireless Technologies Brett Moyer said, “In order to bring our 10 years’ of experience in immersive audio solutions to the mainstream markets, we needed an established semiconductor partner whose IoT Wi-Fi chip roadmap aligned with our strategic plan. Realtek fit the bill. With their strong lineup of audio and video chips, and their long list of tier one consumer electronics customers, there is no better partner to bring WiSA’s spatial audio capabilities to the masses.”

WiSA and Realtek expect samples to be available in 2022.
