Functions

Basic functions.

In order to use SpatialAudio, you need to initalize it using Init, and register the listeners that you plan on using with any of the services offered by SpatialAudio, using RegisterListener respectively, after having registered their corresponding game object to the sound engine.

Warning: At the moment, there can be only one Spatial Audio listener registered at any given time.

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::Init (const AkSpatialAudioInitSettings &in_initSettings)

Initialize the SpatialAudio API.
More...

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::RegisterListener (AkGameObjectID in_gameObjectID)

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::UnregisterListener (AkGameObjectID in_gameObjectID)

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::SetGameObjectRadius (AkGameObjectID in_gameObjectID, AkReal32 in_outerRadius, AkReal32 in_innerRadius)

Helper functions for passing game data to the Reflect plug-in.

Use this API for detailed placement of reflection image sources.

Note: These functions are low-level and useful when your game engine already implements a geometrical approach to sound propagation such as an image-source or a ray tracing algorithm. Functions of Geometry are preferred and easier to use with the Reflect plug-in.

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::SetImageSource (AkImageSourceID in_srcID, const AkImageSourceSettings &in_info, const char *in_name, AkUniqueID in_AuxBusID=AK_INVALID_AUX_ID, AkGameObjectID in_gameObjectID=AK_INVALID_GAME_OBJECT)

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::RemoveImageSource (AkImageSourceID in_srcID, AkUniqueID in_AuxBusID=AK_INVALID_AUX_ID, AkGameObjectID in_gameObjectID=AK_INVALID_GAME_OBJECT)

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::ClearImageSources (AkUniqueID in_AuxBusID=AK_INVALID_AUX_ID, AkGameObjectID in_gameObjectID=AK_INVALID_GAME_OBJECT)

Geometry

Geometry API for early reflection processing using Reflect.

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::SetGeometry (AkGeometrySetID in_GeomSetID, const AkGeometryParams &in_params)

AKSOUNDENGINE_API AKRESULT AK::SpatialAudio::RemoveGeometry (AkGeometrySetID in_SetID)
