# PHASECullOption

The actions the engine takes when it culls sound.

## Declaration

Overview Culling refers to the temporary removal of a sound from the audio output. This enumeration determines the actions a sampler node performs after the engine culls its sound or queues it for culling. To indicate a preference, the app sets a sampler node’s cullOption property.
