THX

THX is a suite of high fidelity audiovisual reproduction standards for movie theaters, screening rooms, home theaters, computer speakers, video game consoles, car audio systems, and video games. The famous THX trailer that precedes movies is based on the Deep Note, with a distinctive glissando up from a rumbling low pitch.

THX was developed by Tomlinson Holman at George Lucas's company Lucasfilm in 1983 to ensure that the soundtrack for the third Star Wars film, Return of the Jedi, would be accurately reproduced in the best venues. THX was named after Holman's initials, with the "X" standing for "crossover" or "experiment". The name is also an homage to Lucas's first film, THX 1138 (1971). Deep Note was created by Holman's co-worker James A. Moorer. THX Ltd. was founded on May 20, 1983 by Lucas and Holman, and headquartered in San Francisco, California.

Cars was made with the help of THX.
