[[File:ADSR parameter.svg|thumb|300px|The amplitude over time of an ADSR envelope. Only the positive half of the signal is shown.]] Sound synthesis techniques often employ an '''envelope generator''' that controls some parameters of a signal or control voltage at any point in its duration. When it controls a [[VCA]] these together form an '''envelope shaper'''.<ref>''Synthesizers for musicians'' by R A Penfold, PC Publishing, 1989, ISBN 1870775015, p.21</ref>

Certain synthesizers also allow for a delay parameter before the attack. Modern synthesizers like the [[DSI Prophet 8]] have DADSR (delay, attack, decay, sustain, release) envelopes. The delay setting determines the length of silence between hitting a note and the attack.
