Sound: Sound Curves – Arma 3

Sound Curves

Sound curve is a simple set of points on 2D graph, which define the relationship between two variables (usually distance and volume).

All sound curves have to be configured in the base class CfgSoundCurves (or directly in curve parameter)

ⓘ

• In array of points {x, value}, x values must be ascending.
• x values are rescaled to range (which means: using 0..1 values represent relative definition, while using meters represents absolute definition, but be sure that the highest x value is the same as range and the lowest x value is 0)

class CfgSoundCurves
{
	class InverseSquare1Curve
	{
		points[] =
		{
			{ 0.0, 0.9751 },
			{ 0.1, 0.6332 },
			{ 0.2, 0.4307 },
			{ 0.3, 0.3009 },
			{ 0.4, 0.2128 },
			{ 0.5, 0.1503 },
			{ 0.6, 0.1043 },
			{ 0.7, 0.0695 },
			{ 0.8, 0.0426 },
			{ 0.9, 0.0213 },
			{ 1.0, 0.0041 }
		};
	};
};

Example of configuration using curve class

class CfgSoundSets
{
	// volumeCurve parameter using curve class
	class Rifle_Shot1_SoundSet
	{
		soundShaders[] = 
		{
			MX_closeShot_SoundShader
		};
		volumeCurve = InverseSquare1Curve;
	};
};

Example of configuration using direct curve definition

class CfgSoundSets
{
	//volumeCurve direct definition
	class Rifle_Shot1_SoundSet
	{
		soundShaders[] = 
		{
			MX_closeShot_SoundShader
		};
		volumeCurve[] =
		{
			{ 0.0, 0.9751 },
			{ 0.1, 0.6332 },
			{ 0.2, 0.4307 },
			{ 0.3, 0.3009 },
			{ 0.4, 0.2128 },
			{ 0.5, 0.1503 },
			{ 0.6, 0.1043 },
			{ 0.7, 0.0695 },
			{ 0.8, 0.0426 },
			{ 0.9, 0.0213 },
			{ 1.0, 0.0041 }
		};
	};
