Deep Note

The Deep Note is THX's audio trademark, being a distinctive synthesized crescendo that glissandos from a low rumble to a high pitch. It was created by Dr. James A. Moorer, a former employee of Lucasfilm's Computer Division in late 1982. The sound is used on trailers for THX-certified movie theaters, home video, video games, and car infotainment systems. The Deep Note debuted at the premiere of Return of the Jedi in Los Angeles. Since then, it has gone on to be a pop culture icon both in meme and cult nature, and had been redesigned and rerecorded for the 2015 "Eclipse" trailer.
