Everything you need to know about the THX certificationIf you pay special attention to details, you’ll have noticed the distinguishing logotype of the THX certification on a great variety of audiovisual material: DVDs, Blu-ray, VHS tapes, videogames, TVs or car and home audio equipment. Besides, depending on the country where you live, you have probably seen this acronym in your favorite cinemas. A common confusion of the general public is believing that THX is an audio coding format, which is not right. The purpose of this mark is to indicate that the final product that has it complies with a group of standard requirements. During its production the THX certification guarantees a high-fidelity sound.
Quality controlThis quality control has its origin at the beginning of the 80s next to the Star Wars Episode V. That was the time when George Lucas, the owner of Lucas film, the company that would create the THX, noticed that the audio quality of movies in most cinemas didn’t fulfill the movie producer’s expectations in terms of fidelity.
These deficiencies led George Lucas to hire Tomlinson Holman, an audio expert, to perform several studies during the production of Star Wars: Episode VI, determine the ideal acoustic condition for cinemas and supervise the mixing techniques in the postproduction of the movie. The objective was clear: the original soundtrack of the final product had to represent what the director and the composer wanted to transmit faithfully. Both the first cinema room and the first movie with a THX certification, Star Wars: Episode VI (Los Angeles in 1983).
The origin of this acronym is uncertain. It makes reference to George Lucas’ first movie, THX 1138. It is also commonly believed that it stands for Tomlinson Holman experiment.
Animations, THX surround sound demonstration. History and evolution.Those cinemas that have a THX certification often show some kind of THX Demo Trailers HD before the movie. Those are basically short presentations through which you can test the sound systems and the acoustic conditions of the room. Sometimes, these THX Demo Trailers HD tend to reach a very high volume, and it is easy to find testimonials who post comments around the internet to say that this type of THX demonstration caused them fear when they went to the cinema.
The THX intro is another element that has evolved since its first appearance; there was a small introduction titled “Wings”, which was followed by a text explaining how the audio systems in cinemas hadn’t changed much in the last 35 years and that they were about to experience this brand new system. Some years later, several versions of this intro appeared, and each of them finished with the common Deep Note Sound. This was shown even with some popular cinema characters, such as Shrek and Horton the elephant. One of the most relevant ones has been the THX Amazing Life and THX tex, a visual and audio wonder.
