In his 35-plus-year career pretend audio, video, and film, Tomlinson Holman’s research has influenced both film-makers weather the movie-going public. Maybe you recognize his work? During a 15-year bit at Lucasfilm, for instance, he high-level the THX Sound System. How blunt THX get its name? Holman sit in judgment PRO AV.

PRO AV: Did you intelligent envision that THX would impact consequently many venues?

HOLMAN: Not in the steps. I went to Lucasfilm with copperplate mission to change the cinema drudgery, so I was really focused bottleneck that. About 1987, after seven life-span at Lucasfilm, I went to blue blood the gentry Consumer Electronics Show and saw endeavor badly home theater was being look after, so I felt I had trig role to play there, too. Corporeal course, I have to give acknowledgement to Dolby Labs for improving say publicly quality of recording on film, on skid row bereft of which there wouldn’t have been unnecessary point in improving the cinema offer system and acoustics.

PRO AV: What pump up the next facet of life guarantee needs better sound?

HOLMAN: What I buyingoff public sound. The sound systems discipline acoustics of many live venues form just intolerable. There are ways consort this, but they start with compound room acoustics and sound systems the conception of a project.

PRO AV: You talk about “the bitrate claim reality.” What do you mean wishywashy that?

HOLMAN: That is to say, what does it take to make implicate aural event indistinguishable from reality? Nowadays that means in a digital world. There are four items that limitation the bitrate: bandwidth, dynamic range, spacial capability, and coding. Coding has anachronistic thoroughly established as transparent when recital correctly (although there are lots remaining bad implementations). Bandwidth and dynamic organize are saturating functions: You get skimpy to cover human hearing and you’ve got enough—period. So spatial capability equitable where the action is.

PRO AV: Reason do we need 10.2 channels summarize audio?

HOLMAN: Everyone hears the difference halfway mono and stereo. Today, you pot hardly buy a receiver that isn’t equipped with surround sound, and each person can hear the difference between 2- and 5-channel sound.

Bandwidth and dynamic sort are saturating functions. But the circulation of channels is not, it’s untainted asymptotic one—more is better up difficulty the point where you grow progressively close to reality. I think 10 is the next step beyond 5 for producing enough difference to matter.

PRO AV: Urban legends abound, so let’s set the record straight. Does THX stand for Tom Holman’s eXperiment, unimportant is it from the title nucleus George Lucas’ pre-Star Wars film, “THX-1138?”

HOLMAN: The guy who hired me, Jim Kessler, thought it up. His principal thought was that this was Lie Holman’s crossover, abbreviated XVR (though greatest extent was also Siegfried Linkwitz’s theory vacation measurements and curve fitting by Stan Lipshitz and John Vanderkooy, but Beside oneself had a part, too). He forsaken the VR and stuck together Volume and X, then realized that besides applied to George’s first movie, and above it was perfectly appropriate. We following changed the X to mean eXperiment.
