	<brief_description>
		Adds a soft clip Limiter audio effect to an Audio bus.
	</brief_description>
	<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.
