THX Ltd. announced the release of a rejuvenated 'THX® Deep Note™' composed by its creator, Dr. James 'Andy' Moorer, thirty years after its iconic original debut. The regenerated 'THX Deep Note' will be available to audiences in certified theaters worldwide beginning in April. The iconic sound will also launch the company's highly-anticipated cinema trailer, THX 'Eclipse'. Audiences can get a first glimpse at the THX 'Eclipse' trailer and remastered audio logo online at

Moviegoers are no stranger to the 'THX Deep Note', the familiar sound that introduces a feature film in THX Certified venues and on certified DVD and Blu-ray discs. It was first composed by Dr. Moorer, a Lucasfilm sound engineer, in 1982 and debuted in the THX trailer Wings, screened before the 1983 premiere of Star Wars: Episode VI - Return of the Jedi. Since then, the 'THX Deep Note' has permeated the film industry to become one of the most iconic audio logos in the world.

"When I created the 'THX Deep Note' I wanted a big sound; I had no idea that sound would have such a big impact," says Andy Moorer, now a Principal Scientist at Adobe Systems. "I'm astonished by how widely-recognized the 'THX Deep Note' has become."

With the essence of the piece remaining true to the original, Dr. Moorer resynthesized the 'THX Deep Note' using modern technologies and mixing it in current cinema audio formats at the historic Skywalker Ranch. Due to technology limitations of the time, the original piece is a four-channel recording that has been adapted over the years for various trailers in up to a 5.1 mix. Without the technical hurdles he faced thirty years ago, Andy Moorer has developed variations of the 'THX Deep Note' in three different lengths (30 seconds, 45 seconds, and 60 seconds) all in stereo, 5.1, 7.1 and Atmos mixes. Faithful to the original character, the resulting audio is intensely more complex, taking the audience on an epic sensory journey unlike anything they've experienced before.

"It's more than a logo, it is an essential part of the moviegoing experience," explains Louis Cacciuttolo, THX Executive VP of International Business Development and Brand Strategy. "I am amazed at how Andy was able to preserve the spirit of the original 'THX Deep Note' in his rejuvenation; and the visual complement of the THX 'Eclipse' trailer will further enrich the experience. I have no doubt that the renewed Deep Note will continue to resonate with movie lovers for years to come."


The famous THX crescendo, Deep Note, is like no other audio mark in the world. But where did it come from?

When THX was founded, the company was looking for a truly unique sound effect. A sound that would test the frequency and dynamic range of a theater’s acoustics and surround sound system, while also letting the audience realize that they weren’t in just any typical movie theater.

Working with the artists and engineers at Lucasfilm’s Skywalker Ranch, THX developed an algorithm that produced a beautiful and mysterious electronic sound. This creation continues to wow and impact audiences around the world and sets the stage for a superior entertainment experience.

A THX trailer consists of stunning audio and visual effects, with each trailer taking on its own personality. A few of the artists that have brought these trailers to life include, John Lasseter at Pixar, who conceived the animated character Tex; Gary Rydstrom, the seven-time Academy Award®-winning sound designer whose credits include “Jurassic Park” and “Finding Nemo;” Skywalker Sound’s Gary Rizzo and Steve Boeddeker; veteran composer, Marco d’Ambrosio; and Van Ling, the renowned visual effects supervisor.


Founded by George Lucas 30 years ago and recognized by audiences around the globe, THX is synonymous with the certification of world-class cinemas and recording studios, premium audio systems for home and automotive applications along with high definition and 4K displays. THX develops and licenses new technologies and specifications for audio and video applications.
