What are Sound 3D Processors? How do I define them? How do I use them in my audio config?
Sound 3D Processors
In the old audio engine any stereo file that was supposed to be positional in the 3D world (gunshots for example) was downmixed to mono. Using stereo sounds can enhance the soundscape tremendously which is why Sound 3D Processors were introduced. Here is an example configuration.
class cfgSound3DProcessors
{
class default3DProcessingType
{
type = emitter; // emitter or panner, chooses between the available processors
innerRange = 0; // range at which the chosen processor is working at 100%, result depends on processor
range = 50; // range at which the chosen processor starts turning 100% mono into "3D processed stereo sound"
rangeCurve = LinearCurve; // normally the transition between 100% mono and 100% "3D processed" is linear, but you can use curves defined in CfgSoundCurves to change that behavior
radius = 3; // ONLY FOR EMITTER maximum radius between the virtual speakers
};
};
Stereo Emitter
The Stereo Emitter creates two virtual speakers in the 3D world, each speaker is playing back one channel of the stereo file. Only stereo files are supported at the moment. The position of the speakers depends on parameters in the configuration and the distance to the listener. When the listener is beyond the range distance both speakers are sitting on two opposite sides of a circle with the radius of 0 on the sound source. You could say they are in the same position. As the player crosses range the speakers start moving away from sound source as the radius of the circle increases to a maximum which you set with the radius parameter. Maximum radius is reached at innerRange.
The virtual speakers copy the cameras rotation, so if you are infront of the sound source and rotate yourself 90° to the left, your "ingame ears" and speakers will all line up. A small visual comparison: You might know particle effects in video games that seem to always look at you and rotate with you. The stereo emitter has the same behavior.
