Splash, Splatter, Sploosh, and Bloop!

Posted by samzenpus on from the wouold-you-like-some-ottamottapia-with-that dept.

Acoustic Bubble writes "Researchers at Cornell University have developed the first algorithm for synthesizing familiar bubble-based fluid sounds automatically from 3D fluid simulations, e.g, for future virtual environments. The research (entitled 'Harmonic Fluids') will appear at ACM SIGGRAPH 2009 in New Orleans in August 2009. Check out some videos of falling, pouring, splashing and babbling water simulations (computed on a Linux cluster)."

    This is a simulation physicist's wet dream, and I'm sure it'll be somewhere in a graphical adventure soon.

    My bet is that the FPS genre will like this too.

      From TFA, three single drops of water took one and a half hours to simulate. The babbling water simulation took over 12 hours.

      I'm assuming that the simulation can then be used to add distortions. Say, water trickling down a creek, and ducks splashing. The two sounds would be distorted by both the direction they are coming from and the interaction of the two sounds. The idea would be to make the sounds more realistic without having to record every possible case.

      Mind you, I haven't yet read the article (or summary) and I am not a sound engineer of any sort.

  4. In other news... by youn · · Score: 4, Funny

    In other news from the overpriced useless ressearch dept... the research has found an unexpected application... generating fart sounds from facial expressions... thus giving speech to farts. a student called in for volunteer testing of the system said, "amazing! it actually sounds like me... I was always embarassed because my farts didnt make any sound... now I know wether it is a pzzzt or a plrrrrt or a puffff.... Thank you"

    Privacy right groups caution against wide use of the system, "We got to preserve the right to privacy while farting... imagine if these devices were everywhere? our privacy would be gone like the wind"

  5. The simulation sounded muffled. by Ungrounded+Lightning · · Score: 3, Interesting

    The simulation sounded somewhat muffled, like the high frequency components weren't right or weren't of sufficient amplitude.

    Can some of the rest of you listen and tell me if it sounds muffled to you too? (I want to be sure it's not my machine or earphones.)

    Might be the CODEC used with flash rather than the original simulation itself...

      The effect reminds me strongly of the water sounds in Myst. I think it's an artefact of recording flowing water in isolation: without an environment to reflect the sounds, the frequency mix isn't right.

      Yeah, I agree. In all honesty the sounds are about as good as the animations. Recognizable, but clearly not real. I think they would have done better if they had just gotten a microphone and sampled some real water.

      On the other hand, maybe someone with a good ear can come along and adjust the algorithms until they really DO sound good. Much like computer visual art isn't all that great unless someone with artistic talent is deploying it.

    I'm pretty stodgy. All I could think of was the Brownian motion poem:

    Big whorls have little whorls
    Which feed on their velocity.
    And little whorls have lesser whorls,
    And so on to viscosity...

    I don't think you understand the word simulation. It's all computer-modelled; you can't take a picture of some plasma and expect the computer to simulate it.
