The audio engine SceneKit uses for playing scene sounds.
Declaration
var audioEngine: AVAudioEngine { get }Discussion
SceneKit uses this audio engine to play sounds from SCNAudioPlayer objects attached to nodes in the scene. You can use this object directly to add other sound sources not related to scene contents, or to add other sound processing nodes or mixing nodes to the audio engine. To identify the node SceneKit uses for spatializing scene sounds when connecting other nodes, use the audioEnvironmentNode property.
