Class reference
AudioEffect
Inherits Resource
Base class for audio effect resources.
Description
The base Resource for every audio effect. In the editor, an audio effect can be added to the current bus layout through the Audio panel. At run-time, it is also possible to manipulate audio effects through AudioServer.add_bus_effect(), AudioServer.remove_bus_effect(), and AudioServer.get_bus_effect(). When applied on a bus, an audio effect creates a corresponding AudioEffectInstance. The instance is directly responsible for manipulating the sound, based on the original audio effect's properties.
Methods
AudioEffectInstance _instantiate() virtual required
AudioEffectInstance _instantiate() virtual requiredOverride this method to customize the AudioEffectInstance created when this effect is applied on a bus in the editor's Audio panel, or through AudioServer.add_bus_effect().
extends AudioEffect
@export var strength = 4.0
func _instantiate():
var effect = CustomAudioEffectInstance.new()
effect.base = self
return effect
Note: It is recommended to keep a reference to the original AudioEffect in the new instance. Depending on the implementation this allows the effect instance to listen for changes at run-time and be modified accordingly.
