Okay with speakers it doesn't sound like there is 3D much, but ... with headphones it does.

The thing is even with 'miles 2D' .. if you put MOH:AA in headphone mode, wear headphones, and in my case put the TB Santa Cruz (not sure if it makes a real difference with SC for headphone vs. 2 speaker) it actually sounds like things are back in of me.

I'm wondering if they used some kind of effect, where instead of using actual 3D algorythmns they managed to change pitch, frequency, sound levels to where if you are facing a sound it 'sounds' different in front of you than in back you - and actually sounds like it's in the back or front.

Is that possible?

This should work for the demo too, if you don't have the full version.

Try putting MOH:AA in headphone mode, and play it using headphones. The sound is actually different depending on your location.

See if it works.

What did it do for you?

Kinda like sorround sound?

Yah but give it a try .. it could be my imagination but I think it does work.. they seem to use some effect to change the way sound is processed when it's front or back of you.. seems...

Try it and listen to things in back or front of you... can you tell if you close your eyes?

Be sure to put it in headphone mode.

This is pure speculation until I find the truth.

The thing is with moh:aa there are no '3d sound drivers'. I am wondering if they simply did it with the sound itself so the designer recorded sounds to give off those sound cues (ricochets from such and such location) gun shots from behind are a different sound file than in front.

If that's the case it does have 3D but not in the typical implementation.

In otherwords the Head-Related Transfer Functions (HRTFs) are recorded in the actual sound files and certain files are played depending on where you are - and their sound levels adjusted accordingly - as opposed to playing a generic sound file and depending on the sound card driver to translate the HRTFs (through Sensaura, EAX, DSD3D) in order to provide 3D positioning.

It would explain why 4 speaker mode wouldn't work because it wouldn't properly translate via all 4 speakers, but 2 speaker would sort of work, and headphones would definetly work.

I'll see if there are different wav files for different sounds (front and back) .. if so it means that's how it was done (which explains why the majority of the game is tons of wav files), but if not, I'm just hearing things. =)

Or the game's sound engine is adjusting HRTFs independently of the sound card drivers - which is more likely.

OMG... You have got to play this game with headphones.. Im not sure if the 3D sound idea that quiet was talking about works, but my god, just playing any level in the game, with headphones, makes it feel so much more real. So much more intense. I just replayed the Omaha level. You acctualy get a sence of what the men that day went through. Especially when you get inside the bunker. If your headphones are any good, and if they are turned up.. it just sounds so real. Freaky at first, since i was playing it at 3 in the mornin. I also tried the first mission on level 4 (Where i currently am in the game http://www.alliedassault.com/ubb/smile.gif ) and wow... i was there.

Point being, you have got to try this game out with a good pair of headphones, with the volume turned up a bunch. It will make you have a whole new respect for the game. http://www.alliedassault.com/ubb/smile.gif

yea i changed the settings to headphones, sounds a little different,
first time i was on snowy multiplayer map i thought the dogs where real and where near my house or something but they are part of the game it turns out.

Anyway i can't tell about the sound, maybe test by being near something that makes a long sound and seeing if the sound changes when you rotate, if it does change, it means the games uses 3d effects generated by the soundcard, if it only changes based on which way you are facing at the start of the sound, it means it plays a seperate wave depending on whether the sound is in front of or behind you. Overall Thumbs up for the sound in this gam
