	where {} means optional and repeatable and [] means optional.
	dB values are floating point or -inf'; times are in seconds.


contrast [enhancement (75)]


dcshift shift [ limitergain ]
	The peak limiter has a gain much less than 1.0 (ie 0.05 or 0.02) which
	is only used on peaks to prevent clipping. (default is no limiter)
