The SubtleSonic EnvelopeShaper processes the sounds by boosting or cutting the attack or decay. It does this by comparing the difference between two volume levels, one fast and one slow. You can use it to extend the sustain of a sound, or soften the attack…or do the opposite.
The video demonstrates more drastic modifications, but you can also use it to subtly boost attacks or decays as well.
