**继承：** :ref:`AudioEffect<class_AudioEffect>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
|
|
|

**派生：** :ref:`AudioEffectEQ10<class_AudioEffectEQ10>`, :ref:`AudioEffectEQ21<class_AudioEffectEQ21>`, :ref:`AudioEffectEQ6<class_AudioEffectEQ6>`
|
|
|
|
音频均衡器的基类。让你可以控制频率。
|
|
|
|
如果 :ref:`AudioEffectEQ6<class_AudioEffectEQ6>`\ 、\ :ref:`AudioEffectEQ10<class_AudioEffectEQ10>` 或 :ref:`AudioEffectEQ21<class_AudioEffectEQ21>` 不符合你的需求，请用它来创建自定义均衡器。

描述
|
|
----
|
|
|
|
AudioEffectEQ 可用于频率控制。用它来弥补音频中不足之处。AudioEffectEQ 在 Master 总线上很有用，可以完全掌控一个混音，并赋予它更多的特性。当游戏在移动设备上运行时，它们也很有用，可以根据那种扬声器来调整混音（可以被添加，但在插入耳机时禁用）。
