ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,483,452, issued on Nov. 25, was assigned to Turtle Beach Corp. (San Diego).

"Parametric signal processing systems and methods" was invented by Elwood G. Norris (Poway, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for generating a modulated carrier signal that can be emitted as a parametric wave includes measuring an average amplitude of an audio signal, and adjusting an average amplitude of a carrier signal based on the average amplitude of the audio signal. The carrier signal is then modulated with the audio signal to generate a modulated carrier signal. Various circuits, components and software are also provided for implementing the ...
