AudioEffectLimiter
==================

**Inherits:** :ref:`AudioEffect<class_AudioEffect>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

Adds a soft-clip limiter audio effect to an Audio bus.

.. rst-class:: classref-introduction-group

Description
-----------

A limiter is similar to a compressor, but it's less flexible and designed to disallow sound going over a given dB threshold. Adding one in the Master bus is always recommended to reduce the effects of clipping.

Soft clipping starts to reduce the peaks a little below the threshold level and progressively increases its effect as the input level increases such that the threshold is never exceeded.
