Class AudioEffect

Base class for audio effect resources.

Inheritance
AudioEffect
Derived

Remarks

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

_instantiate

Qualifiers: virtual

Override 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.
