This reverts commit 57781dc0bc.
The rename, although in line with what we did in the engine, caused problems with RTD we need to fix (or push for a fix) first.

描述
|
||
----
|
||
|
||
限制器是一种旨在阻止声音超过给定dB阈值的效果。硬限幅器预测音量峰值，并将在峰值超过上限阈值时平滑地应用增益降低，以防止削波和失真。它保留了波形并防止其越过上限阈值。建议在主总线中添加一个作为安全措施，以防止出现突然的音量峰值，并防止由削波引起的失真。

波形的最大允许值，单位为分贝。此值的范围可以是 ``-24.0`` 到 ``0.0``\ 。

默认值为 ``-0.3``\ ，可防止潜在的采样间峰值（ISP）跨越 0 dB，这种情况可能会在一些较旧的硬件上造成轻微失真。
