sounds in 3D

Greetings Colleagues, I would like to help me put sounds 3D game engine blender 2.5. My idea is similar to approach a car or out of this.

you can simply add a sound actuator and turn the 3D sound on, then you need to change the values to make the sound more close to what you want, then it ll change its loudness as it goes close or far from the camera.

My problem is I do not know the values ​​that I changed to operate as a 3d sound real.

I need to see an example

Is your sounds a .wav or .ogg? If not then there is your problem…

And here is a link to a .blend… http://www.tutorialsforblender3d.com/Blender_GameEngine/Sound/Sound_6.html

I hope it helps!
