To give you a real-world example, the main difference between the
sound of the wind and the sound of a snare drum is that they have very
different volume envelopes. Otherwise, they are essentially both white
noise. Wind has a relatively slow attack, a long sustain, and a long decay
and release. A snare drum has a sharp attack, no sustain, and very little
decay or release. But again, they are both fundamentally white noise.

setting, the slower the attack time and the longer it takes for a sound to
reach its full volume. Pads typically have softer (longer) attacks. Percus-
sive sounds have sharper (shorter) attacks.
