+<p>Generates an ADSR (Attack, Decay, Sustain and Release) envelope.</p>
+
+<p>Driven by a gate signal - if the level of the signal goes higher than the
+Trigger Threshold, the attack stage begins, proceeds to the decay stage and
+then holds at the sustain level. The release stage begins when the gate falls
+below this theshold - even if the previous stages have not completed.</p>
+
+<p>The output is a signal between 0.0 (rest) and 1.0 (peak) and the transitions
+are linear.</p>
