\ **注意：**\ 该成员会帮助修改 :ref:`volume_db<class_AudioEffectAmplify_property_volume_db>`\ 。返回的值等价于使用 :ref:`volume_db<class_AudioEffectAmplify_property_volume_db>` 调用 :ref:`@GlobalScope.db_to_linear()<class_@GlobalScope_method_db_to_linear>` 的结果。设置该成员等价于将 :ref:`volume_db<class_AudioEffectAmplify_property_volume_db>` 设置为使用新值调用 :ref:`@GlobalScope.linear_to_db()<class_@GlobalScope_method_linear_to_db>` 的结果。
