Sound envelope, in musical sound,
the attack, sustain, and decay of a sound. Attack transients consist of changes
occurring before the sound reaches its steady-state intensity. Sustain refers
to the steady state of a sound at its maximum intensity, and decay is the rate at
which it fades to silence. Every musical instrument has its characteristic
attack, sustain, and decay pattern. Attack transients are very complex and
difficult to characterize because of the speed with which the character of the
sound changes in its first few milliseconds.
A: Attack
D: Decay
S: Sustain
R: Release
Sounds with short attacks (sounds that are struck or plucked):
Drums, most percussion instruments such as piano, tambourine etc.
Long sustain: Horror movies to create a tense atmosphere, sad romantic movies to create either a moment of happiness or moment of sadness

Sounds with long attacks:

Examples of where you might use these sounds:
Strings or piano for horror films to create a tense feeling, strings for a romance movie, drums for a fast paced scene.

Ummmm. Sort of!
ReplyDeleteYou need to be more specific. Essentially, cars and motorcycles may have both a long or short attack depending on the sounds they are making. An engine revving for instance may have a long attack as its volume increases.
