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."

    As funny as that is (and strangely accurate), it just doens't sound quite right on my THX-certified speaker system. That said, I just found a new Windows shutdown noise. Maybe the actual THX one for booting...

    I don't know about Super Mario, but my wife calls the THX sound the "Orgasm sound".

    And you know what, she's right. If any of you slashdotters ever get a girlfrie^H^H wife, check it out!
