Sound Modeling

Recommended Posts

Speed of sound? This has always bugged me a bit with CMX1 - You'd see an explosion and hear it at the same time, even if you were kilometres away.

Attenuation/echoing with distance?

Perhaps if you select a unit, you hear what they'd hear, regardless of where the view point was.

Hmm, one for the poll thread, methinks.

NOW that would be ground breaking

Speed of sound modeled in the game?

You see the BANG far away and depending on where the camera is and the distance from the "BANG" you would hear (in the computer speakers) the sound of the BANG sometime later...

now just how hard would that be?

Unladen flight speed modelling optional.

If by some unlikelyhood the new game is set in North America, I fully expect Steve to fly over and record European bird song just to annoy us. :D

On the speed of sound thing: Eeewwww, no thanks! Is it realistic? Yes! But I still hold the view that it isn't CMx1 (or Hollywood) who's portrayal of sound is wrong rather I hold the view that the laws of physics themselves stuffed up and should be changed. :D It would be increasingly hard to follow what was going on and who was doing what to whom. Besides, I would think the computational power needed to keep track would be prohibitive.

It would make it trickier, but it would be great fun. You'd get the rounds of a high-velocity gun goingpast before you hear the report of the gun. That would also require tracers as light sources, so you can see them.

CMX1 already lowers the volume depending on where your view point is relative to the source. Adding a corresponding delay shouldn't be too hard*. It wouldn't have to be too accurate, just so long that at about a kilometre it's about a second would suit me fine.

Really I just want to see a hill light up under artillery fire in silence, then hear the thunder. It's not groundbreaking - it's been modelled in at least one other game (it might be Operation Flashpoint, but I could be wrong). It's certainly not usual.

*I might be entirely wrong on this, as my programming skills are somewhat limited. Nonetheless it's a function that depends on an existing variable.

... and if you change the unit selected, you might either never hear the round fired (the soundwave hasn't reached the old unit, but has already passed the new unit when you select it), or hear it twice (the new unit is further away from the source than the old one). Now, that would be confusing as hell.

And on a noisy battlefield you'd have no way of telling which sounds you'd missed altogether, ad which you'd heard twice.

Im with flamingknives. The sound that traveled at the speed of light bugged me. I would love to see the modeling of the speed of sound. Now I know immersion is not as big a part of this type of game, but when I first played the demo of CMBO and the artillery dropped, the screen shake from "concussion waves" made me like it that much more. I think speed of sound will add that again. Its always the little things like that, that get me.

Speed of sound has bugged me too. (But it also bugs me when those numbskulls in Hollywood keep syncing the lightening and thunder sounds.)

The issue with selecting units and losing sound would only occur during playback. This is still going to be a WEGO system? Hmm, I wonder what would happen if during playback I spun the map around frantically while there was gunfire and explosions?

I think that it will add to immersion. I also like attenuation and/or echoing with distance, but that might take a bit of programming time/processing power.

Cheers,

Gabe

Well, duh. There isn't an awful lot of firing going on during the orders phase, now is there :rolleyes:;)

Speaking of sound, I think an interesting issue would be to try to reproduce the way sounds transform with distance. For example, if you are listening to a fire fight from a distance, gun shots do not sounds as crisp as up close on the firing range.

Also, I don't know if it's possible, (but I'm pretty sure it ain't easy ;) ...) but some sort of doppler effect would be quite impressive too. Arty shells roaring over head or bullet buzzing past your ear... I know there are limitations on this count (basically the number and position of speakers) but I'd be willing to go surround if the game uses it....

My 0,02 $ CAD. Cheers.

Details, details.

Wouldn't that be a part of the "crunching"? So it is already factored in while you are viewing the action. Right?

It can't be, as you can move your viewpoint around after the 'crunching' has taken place.

How about a slider for ambient sounds?

I was one that whined about the volume of the wind and "storm" sounds and felt it was just distracting and/or too loud relative to other sounds. I like them both and think they add to the immersion, but the all-or-nothing setting just caused me to stop using them.

Infantry voices: some a quite good, a few are very silly, or innapropriate. The only "problem" I have with them is that I hate it when contact has not yet been made Gomer Pyle yells out "OKAAAY SAAARGE!!". Especially at night. :mad: :D I know it doesn't affect the game itself, but I cringe every time and it hurts the immersion.

I guess my overall approach would be to focus on general "noise of battle" sounds---"I need ammo!", "Put some fire on that house!", "Medic!", that kind of thing---over the rest of it.

Don't mean to sound too negative on that stuff, as most of it is quite good as it is.

Vehicle sounds: I'd like more realism and variation in those, especially AFVs. Not unique ones for every vehicle by any means, just engines gunning when movement starts, when AFVs are turning, etc. Having a few different sounds in differnt terrain would be cool---on pavement, in trees, mud, and whatnot.

Weapon/gun/explosion sounds: they are largely fine the way they are (and there are some excellent mods, of course) so I don't see any huge need for drastic change there.

Though I think modelling the speed of sound would be cool, it'd be purely window dressing to me. Payoff would not be worth the coding effort/additional engine stress.

I hope the Aussi voices say nothing but "G'day mate!", and "Look at that croc"!. Paul Hogan would love to be a part of this project I'm sure.
