Sounds sort of like Saturn's
radio emissions [uiowa.edu]...
Does everything around
Saturn sound the same? Perhaps it's all eminating from a
single source? I dunno, maybe some sort of black rectangular
monolith? |

chipmunks on speed, gnawing away at my
eardrums.
Seriously though... this is interesting
stuff. I mean, if we can simulate physics for the earth, and
its weather patterns... then why couldn't we simulate the
physics of sound?
Sound is, after all, just vibrations
from things hitting/passing each other... One would think that
on a powerful enough computer, you could simulate the liquid
methane flowing down over and crashing into...
whatever.
I mean, I'd for one like to see a game where
the sound wasn't pre-recorded stuff played when two objects
collide their meshes together... Could you imagine having a
game engine advanced enough where depending on what kind of
shoes your wearing--and how fast your walking/running--the
sound would change automatically from click-click on tile to
the soft pad on carpet? All without any
programming?
And then there's the whole car crashes,
and gunshots, and echoes... That stuff's hard to program
normally. And the best thing is, because its all generated at
'runtime' if you will... the sounds never get repetitive. Its
always exactly how its supposed to sound, for exactly where
you are. |

Ok, I know someone already posted a response
similar to this under another topic somewhere
recently, but I don't remember where, so I'm going to
paraphrase and recap.
The reason sound can't be
simulated quickly in a game is the same reason light
can't. Sure, there are games that have dynamic
lighting and so forth, but in terms of actual
raytracing, we're just approaching the possibility of
having a playable real-time raytraced game - and that
would require a behemoth of a machine.
Now, think
about sound. If I drop a penny in a perfectly cubic
room, the penny deforms a bit, as does the floor. The
distortion (and return to normal) causes the sound
wave. This wave then bounces off of all of the
surfaces in the room, including the penny,
overlapping, creating harmonics, etc. Even that would
be tough to simulate. Now, imagine, for instance, a
FPS. Complex, moving, 3D objects, all interacting, all
creating sounds that bounce around. While this
wouldn't be impossible to simulate, I wouldn't expect
it to happen in realtime anytime soon. |

I'm not totally convinced that it's completely accurate.
At the site, they have recordings of their technique applied
to recreate sounds of waterfalls on Earth--i.e., artificial
Earth waterfall sounds. Those artificial sounds bear only a
modest resemblance to actual waterfall sounds (which they have
a recording of also).
The actual terrestial waterfall
sounds seem to have more low-frequency noise than is
reproduced by their technique. The high-frequency noise of an
actual waterfall, moreover, seems to be more complex--it seems
to have a more "springy" or "reverbatory"
quality.
There is a resemblance between the actual
waterfall sounds and their simulated sounds--I don't mean to
suggest they're radically different. It's just that the
artificial earth sounds are different enough from the actual
earth sounds, that I can't tell what to expect the actual
Titan methane sounds to be like.
While I appreciate
them being honest and straightforward about what their
technique is, and what it produces, I'm a little skeptical of
how realistic it is.
I'm also a bit surprised they took
such a deductive, basic-physics approach to doing the
simulation, rather than taking a more inferential,
data-compression approach.
Oh well. Interesting, but
seems to raise as many questions as it answers. |

| Wouldn't the sound of a specific fall greatly depend on
the size and shape of the fall, the volume of material
flowing, what it's flowing over and into, etc...? Otherwise,
all waterfalls on earth should sound the same and I know that
is not the case. |

Either the codec in my wav player is screwy or that is the
gorram scariest liquid noise I have ever heard.

| Either that, or the rocks under the methanefall on Titan
are all made up of hollow tin (or maybe, the sound is close,
Replicators from Stargate SG-1). |

I suspect some very clever people have put many months of
effort into this simulation software to generate those 9
precious seconds of audio.
I would like to believe that they chose to release their 9
second audio clip as a .wav file because
they felt their work was so accurate that to compress the data
in any way would detract from the quality of their fine work.
However, being a “cynical git”, I'm inclined to think we
are downloading a 976KB file as a result of them just not
bothering to encode it as an mp3 :-)
