Graue softsat is a little tube-style saturating limiter that
I like to use for mastering purposes. It keeps the input
below 0 dB by adding minimal, warm sounding distortion.

The formula this implements is from Bram de Jong:

This effect is little more than an implementation of that
formula, so thank him for how good it sounds.

The "hardness" control is a tradeoff between the amount of
distortion (harder = more distorted) and how much quieter
the input gets (softer = quieter). The default value of 0.5
usually seems to work well. Unless your song is rather loud,
you might not even notice a difference between 0.0 and 1.0
-- it can be subtle.
