How The THX Noise Was Created

devilsbrigade writes "The blog MusicThing is running an interesting interview with Andy Moorer. Mr. Moorer is the man who created the sound called Deep Note, now heard in every THX-enabled movie theatre. The interview is originally from last year, but the tech-heavy discussion is still a timeless analysis of a great sound." From the article: "The score consists of a C program of about 20,000 lines of code. The output of this program is not the sound itself, but is the sequence of parameters that drives the oscillators on the ASP. That 20,000 lines of code produce about 250,000 lines of statements of the form "set frequency of oscillator X to Y Hertz. The oscillators were not simple - they had 1-pole smoothers on both amplitude and frequency. At the beginning, they form a cluster from 200 to 400 Hz. I randomly assigned and poked the frequencies so they drifted up and down in that range."

Now the art is

[Too many errors, bai]

to turn that sound into an onomatopoeia. Any takers? "Bhhwuhhhhhhhhhhoooooh"

pfft ... 20k lines of C

[Anonymous Coward]

could've done it in 5 lines of perl

I always thought it was

You know, a slowed down version of the sound of what happens after George Lucas unzips his fly.

They created it by

recording the sound inside my head when my former wife talks.

I like the THX signature sound so much...

[E-Lad]

That depending on the movie that follows it, that sound is the best part of the sitting.

Their stated goal was to demonstrate the clarity or depth or somesuch without being overpowering...

But there actual goal was to get everybody in the theater to SHUT THE FUCK UP and listen to the movie, which requires a burst of sound so loud that nobody can talk over it.

Probably the THX logo.

Ug Make Fire! Story next on RockDot.org

Here's how it *really* went down

[popo]

George Lucas: How'd you make that sound Andy?

Andy Moorer: We electrocuted a sperm whale.

George Lucas: God damn that sounds great.

Andy Moorer: [Giggles} I *know*

George Lucas: Thing is... we need a story that's not going to bring those Greenpeace punks down on top of us.

Andy Moorer: I coded the sound with 20,000 lines of C?

George Lucas: Nice. Let's go with that.

My date was mortified; still got laid, though.

Do you know for sure that she got laid? She might only have told you she did out of spite ;)
