WiSA Technologies, Inc. develops wireless audio technology aimed at immersive, multichannel sound for intelligent devices and home entertainment systems. Historically, the company has sold custom semiconductor chips and wireless modules that transmit and receive uncompressed audio directly to speakers, supporting up to eight channels at 24-bit and up to 96 kHz sample rates, with low latency and speaker synchronization suited to video applications. Customers integrate these modules into products such as speakers, TVs, soundbars, set-top boxes, streaming devices and HDMI dongles, and the company names Bang & Olufsen, KEF, LG, Harman International (a division of Samsung), Savant, Skyworth and System Audio among its consumer electronics customers.

In late 2023 it launched WiSA E, a software-based technology that works with standard Wi-Fi chips and third-party IoT Wi-Fi modules. WiSA E is designed to bring immersive audio to entry and mid-level systems, including soundbars and Wi-Fi smart devices, at lower cost and with lower power consumption. Development kits began shipping in late third quarter 2023, and the Discovery module is the first product to integrate the new software.

The company plans to license its proprietary software to other companies for embedding in Wi-Fi enabled devices. Its wholly-owned subsidiary, WiSA, LLC, operates the WiSA Association, an industry group of brands, manufacturers and influencers that sets interoperability specifications, manages testing criteria, certification and logo usage, and certifies WiSA products so that components from different vendors work together. WiSA-certified products must use WiSA modules.

WiSA, LLC also handles IP licensing for WiSA E, and announced a licensing program for display devices such as TVs and projectors in the fourth quarter of 2023, with three manufacturers signing licenses in the first 90 days. The company targets mainstream consumers and audio enthusiasts, and positions its technology against the complexity, cost and wiring of traditional home theater systems and against the latency and channel limits of Bluetooth and standard Wi-Fi audio. It also cites resistance to interference through frequency switching in the 5 GHz band.

Its strategy centers on establishing WiSA as the standard for hi-fidelity wireless multichannel audio by building brand recognition, reducing hardware costs, expanding availability across price points, protecting its intellectual property and working with leading consumer electronics companies.
