**被繼承：** :ref:`AudioEffectAmplify<class_AudioEffectAmplify>`, :ref:`AudioEffectCapture<class_AudioEffectCapture>`, :ref:`AudioEffectChorus<class_AudioEffectChorus>`, :ref:`AudioEffectCompressor<class_AudioEffectCompressor>`, :ref:`AudioEffectDelay<class_AudioEffectDelay>`, :ref:`AudioEffectDistortion<class_AudioEffectDistortion>`, :ref:`AudioEffectEQ<class_AudioEffectEQ>`, :ref:`AudioEffectFilter<class_AudioEffectFilter>`, :ref:`AudioEffectHardLimiter<class_AudioEffectHardLimiter>`, :ref:`AudioEffectLimiter<class_AudioEffectLimiter>`, :ref:`AudioEffectPanner<class_AudioEffectPanner>`, :ref:`AudioEffectPhaser<class_AudioEffectPhaser>`, :ref:`AudioEffectPitchShift<class_AudioEffectPitchShift>`, :ref:`AudioEffectRecord<class_AudioEffectRecord>`, :ref:`AudioEffectReverb<class_AudioEffectReverb>`, :ref:`AudioEffectSpectrumAnalyzer<class_AudioEffectSpectrumAnalyzer>`, :ref:`AudioEffectStereoEnhance<class_AudioEffectStereoEnhance>`

音訊效果資源的基底類別。

|
說明
|
|
----
|
|
|
|
所有音訊效果皆繼承自此 :ref:`Resource<class_Resource>`\ 。在編輯器中，可於「音訊」面板將效果加入目前匯流排配置；執行時亦可透過 :ref:`AudioServer.add_bus_effect()<class_AudioServer_method_add_bus_effect>`\ 、\ :ref:`AudioServer.remove_bus_effect()<class_AudioServer_method_remove_bus_effect>` 與 :ref:`AudioServer.get_bus_effect()<class_AudioServer_method_get_bus_effect>` 動態操作。
|
|
|
|
當效果被套用至匯流排時，會建立一個對應的 :ref:`AudioEffectInstance<class_AudioEffectInstance>`\ ，該實例會依據原效果的屬性直接處理聲音。

覆寫此方法，可自訂在編輯器「音訊」面板或 :ref:`AudioServer.add_bus_effect()<class_AudioServer_method_add_bus_effect>` 套用效果時所建立的 :ref:`AudioEffectInstance<class_AudioEffectInstance>`\ 。

|
|
|
|
@export var strength = 4.0
|
|
|
|
func _instantiate():
|
|
var effect = CustomAudioEffectInstance.new()
|
|
effect.base = self
|
|
|
|
return effect
|
|
|
|
\ **注意：** 建議在新實例中保留對原 **AudioEffect** 的參考，以便於執行時偵測屬性變化並相應調整。
