Foo Lookahead Limiter

This limiter was written to overcome some shortcomings in the limiter used in Jamin. The limiter in Jamin does not perform optimally when it is pushed hard with material containing high transients.

The limiter works by searching for peaks in the signal and triggering attack / release envelopes when such peaks occur in the signal ahead. The attack time of the envelope is constant and as such it can't be parametrized. The envelope is tailored so that the limiter will never allow peaks higher than the parametrized value to pass through it.

parameters

input gain	The amount of input gain applied to the signal before limiting
release time	Release time of the envelope
max peak	Maximum peak to be allowed out of the limiter
log scale	Continuous control of the release curve between a steep log curve and a linear curve (since 1.0)
