Detailed Description

template<class T = real, class Ts = Synced>
class gam::Decay< T, Ts >

Exponentially decaying curve.

This envelope exponentially decays towards zero starting from an initial value. Because zero is never reached, the decay length determines when the envelope is -60 dB down from its initial value. This envelope is one of the most computationally efficient envelopes requiring only a single multiply per iteration.
