# Arma 3: Sound: Global Sound Parameters

Definition of default sound properties, which are applied on every sound if not overridden by custom definition within [SoundSet](../topics/Sound~3A_SoundSet.md).

Configured in the base class **CfgSoundGlobals**.

| Parameter | Unit/Values | Default | Description |
|---|---|---|---|
| `defaultDistanceFilter` | class name | N/A | global [Distance filter](../topics/Sound~3A_Filters.md), used on every sound unless specified differently in the soundSet (meaning vehicles which do not yet have soundSet configuration always are filtered by the defaultDistanceFilter) |
| `defaultSound3DProcessingType` | class name | N/A | global [Sound Processing Type](../topics/Sound~3A_Processing_Types.md) |
| `defaultVolumeCurve` | class name | N/A | global amplitude [attenuation curve](../topics/Sound~3A_Sound_Curves.md) |
| `defaultWeaponVolumeCurve` | class name | N/A | global amplitude [attenuation curve](../topics/Sound~3A_Sound_Curves.md) for weapons shooting |
| `defaultLFEVolumeCurve` | class name | N/A | global LFE (subwoofer) amplitude [attenuation curve](../topics/Sound~3A_Sound_Curves.md) |
| `OldConfigurationVolumeFactor` | float (0..n) or [dBFS] | db0 | volume attenuation of sounds which are configured using the old way (not [SoundSets](../topics/Sound~3A_SoundSet.md)) |
| `defaultSpatialityRange` | [m] | 0 | [innerRadius](https://msdn.microsoft.com/en-us/library/windows/desktop/microsoft.directx_sdk.x3daudio.x3daudio_emitter(v=vs.85).aspx) value - distance, where signal starts bleeding into "opposite" channels |
| `defaultSpatialityRangeAngle` | [radians] (0..pi/4) | 0.785 (pi/4) | [innerRadiusAngle](https://msdn.microsoft.com/en-us/library/windows/desktop/microsoft.directx_sdk.x3daudio.x3daudio_emitter(v=vs.85).aspx) |

```cpp
class CfgSoundGlobals
{
    defaultDistanceFilter = "defaultDistanceFreqAttenuationFilter";
    defaultVolumeCurve = "defaultAmpAttenuationCurve";
    defaultWeaponVolumeCurve = "defaultWeaponAmpAttenuationCurve";
    defaultLFEVolumeCurve = "defaultLFECurve";
    defaultSound3DProcessingType = "default3DProcessingType";
    defaultSpatialityRange = 0.005;
    defaultSpatialityRangeAngle = 0.785; // pi/4
    OldConfigurationVolumeFactor = db-4;
};
```
