Summit Wireless New Low-Cost Module for Spatial Audio Available Now!

Summit Wireless Technologies, Inc. (NASDAQ: WISA), the leading developer of immersive spatial wireless sound technology, has partnered with Espressif Systems to develop the new 2.4GHz wireless audio module capable of delivering the reliability and quality commonly associated with more expensive 5GHz solutions. Based on Espressif's popular and industry-proven Wrover module platform, Summit's transceiver module is production-ready and will be demonstrated at CES 2022.

"We are excited to partner with leading wireless audio companies like Summit," said Swee-Ann Teo, CEO and president, Espressif Systems. "This new entry-level module fulfills the need for a cost-effective solution for sound bars as well as thinner smart TVs that need to connect wirelessly to surrounding speakers."

Marketed as Discovery, the module is designed for fixed, low-latency wireless audio transmission and includes the following features:

• Support for up to four independent 48kHz PCM audio channels
• Fixed source-to-speaker latency meeting video lip-sync requirements
• Dynamic Network Optimization (Dynotm), technology for wireless link reliability and robustness
• Low inter-channel delay between speakers ensuring a distortion free experience.

"Espressif is the perfect partner to help develop and launch the Discovery module," said Brett Moyer, president and CEO of Summit Wireless Technologies, Inc. "We were looking for a partner whose module could meet our performance and reliability expectations for entry-level immersive audio systems and Espressif's module met all the requirements. There is no better proof than the testing done by an independent test house demonstrating that the Discovery module at 2.4GHz performs better than competing 5GHz products sold in the marketplace today while also supporting additional audio channels."

The Discovery module will be demonstrated at CES 2022, January 5 ? 7, in Las Vegas at the Summit Wireless suite at the Flamingo Hotel. To schedule a demonstration, email [email protected]. Evaluation kits will be available January 2022.
