====== ArmA 3 Terrain Tanoa Sounds ======

**Tanoa Environmental Sounds** by kju

Brief overview on new audio tech for terrain objects (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)

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)

4. one assign multiple soundSets to the memory
<code cpp>
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"
	};
};
</code>


5. the soundSet is assigns soundShaders (and various advanced sound parameters)
<code cpp>
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";
};
</code>

6. finally the soundShader has parameters to define under what conditions the sound is to be played (range + volume parameters)
<code cpp>
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;
};
</code>

All related [[http://paste.ubuntu.com/23881843/|soundSets]] and [[http://paste.ubuntu.com/23881866/|soundShaders]].

One can do with this things like rain, animals (insects, birds), wind related sounds, snow related sounds, water spring, church, clock, radio, buzzing, etc.
