WiSA Technologies, Inc. ( WISA ) shares are skyrocketing on Tuesday.

The company’s unit WiSA Association has executed its fourth 5-year WiSA E licensing agreement with a fourth major HDTV/PTV (Projection TV) brand.

The WiSA E license allows the brand to integrate WiSA E software into its products, thereby offering consumers wireless immersive audio options, including interoperability with any of the WiSA E-enabled speakers offered by the many WiSA Association speaker brands.

WiSA E entails a suite of audio features that define how audio should be experienced across HDTVs, PTVs, soundbars, mobile devices, set top boxes, and speakers. 

“We are very pleased that yet another major HDTV brand recognizes the value of our WiSA E technology, as well as our licensing model for market deployment,” said Tony Ostrom, president of the WiSA Association.

WiSA E can be implemented across four HDTV SoC providers, including Realtek, Amlogic, Mediatek, and Novatek, and can be designed to be fully interoperable with WiSA-E enabled speakers.

Price Action: WISA ( WISA ) shares are trading higher by 83% to $3.21 on the last check Tuesday.
