**繼承：** :ref:`AudioEffect<class_AudioEffect>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
|
||
|
||
**被繼承：** :ref:`AudioEffectEQ10<class_AudioEffectEQ10>`, :ref:`AudioEffectEQ21<class_AudioEffectEQ21>`, :ref:`AudioEffectEQ6<class_AudioEffectEQ6>`
|
||
|
||
等化器基底類別，可用於控制不同頻率。
|
||
|
||
若 :ref:`AudioEffectEQ6<class_AudioEffectEQ6>`\ 、\ :ref:`AudioEffectEQ10<class_AudioEffectEQ10>` 或 :ref:`AudioEffectEQ21<class_AudioEffectEQ21>` 不符需求，可繼承本類自製等化器。

||
----
|
||
|
||
AudioEffectEQ 能精確控制各頻段，用於補償音訊缺陷。在 Master 匯流排上進行總體處理或針對行動裝置喇叭調整混音時十分實用（可在偵測到耳機時停用）。
