Brief overview on new audio tech for terrain objects (CfgEnvSpatialSounds)

[.kju 3240]

Pretext: Thanks to Pennyworth for the assistance.

 

 

1. one can define **one** or **more** named selections in memory LOD of a model
2. probably works for any terrain object - so not limited to vegetation (trees, bushes); one can do with this things like rain, animals (insects, birds), wind related sounds, snow related sounds, water spring, church, clock, radio, buzzing, etc
3. the way it works the game looks for the name in CfgEnvSpatialSounds (subclass to EnvSounds in cfgWorlds terrain class - so can be/is terrain specific; or otherwise in cfgEnvSounds - a root base class)

 

class CfgWorlds
{
    class DefaultWorld
    {
        class EnvSounds;
    };
    class CAWorld: DefaultWorld
    {
    };
    class Tanoa: CAWorld
    {
        class EnvSounds: EnvSounds
        {
            class CfgEnvSpatialSounds
            {
                class sound_shrub_smallleaves_1
                {
                    memPoint = "sound_shrub_smallleaves_1";
                    soundSets[] = {"Rain_PlantA_Light_SoundSet","Rain_PlantA_Medium_SoundSet","Rain_PlantA_Heavy_SoundSet","Insect_Day_SoundSet","Insect_Night_SoundSet"};
                };

 

4. one assign multiple soundSets to the memory point placed in the model

 

class sound_shrub_smallleaves_1
{
    memPoint = "sound_shrub_smallleaves_1";
    soundSets[] = {"Rain_PlantA_Light_SoundSet","Rain_PlantA_Medium_SoundSet","Rain_PlantA_Heavy_SoundSet","Insect_Day_SoundSet","Insect_Night_SoundSet"};
};

 

5. the soundSet is assigns soundShaders (and various advanced sound parameters)

 

class Rain_PlantA_Medium_SoundSet
{
    soundShaders[] = {"Rain_PlantA_Medium_SoundShader"};
    volumeFactor = 1;
    frequencyFactor = 0.6;
    spatial = 1;
    doppler = 0;
    loop = 1;
    volumeCurve = "InverseSquare1Curve";
    sound3DProcessingType = "PLant3DProcessingType";
};

 

6. finally the soundShader has parameters to define under what conditions the sound is to be played (range + volume parameters)

 

class Rain_PlantA_Medium_SoundShader
{
    samples[] = {{"A3\Sounds_F_Exp\environment\elements\rains\rain_plantA_medium_001",1},{"A3\Sounds_F_Exp\environment\elements\rains\rain_plantA_medium_002",1},{"A3\Sounds_F_Exp\environment\elements\rains\rain_plantA_medium_003",1}};
    volume = "raindrops * raindrops * (rain factor[0.4,0.6])*(rain factor[0.9,0.7]) * 1.5";
    range = 12;
};

(see image at the top for sample)

 

In regards to memory point positioning: 
It does not have to be at the model center or at the base of the object.

Multiple memory points are fine too.

Thanks for the info kju

Thank you man!

Thank you for the info, it will help me greatly improve my upcoming terrain.

I could be wrong here, but after some testing it appears multiple memory points in the same memory LOD selection do NOT create more sound positions.  It makes sense that they created separate CfgEnvSpatialSounds classes with the same soundSets, so that you could have multiple sound sources in the same .p3d

memPoint = "sound_rain_straw_1"; for straw huts also

great thread!
