USA: 2 April 2010 (Dawson City International Short Film Festival)
Attack Decay Sustain Release was created on 2007-06-18.
the attack and decay are two parts of a note's envelope which have an attack phase, a sustain phase, a decay then finally a release phase. the attack is how quickly the note reaches its loudest point,. take a guitar for example, when the string is plucked it is immediately at its loudest, that is the attack, the sustain is how long the note stays at its loudest point, with a guitar this depends on the strength of the pluck, a strong pluck will give a long sustain where a soft pluck will have a small sustain decay is how long the note takes to drop to go from its highest point to its release point, which is considered its quietest phase, the trail of the note when in the decay phase goes from loud to almost silent, if you look at a guitar string audio wave the decay phase is where the tail begins to get smaller. release is where the sound finally dissipates with a guitar release is immediate after decay, however with electronic synthesis, you have the option to allow a longer release allowing the note to persist for greater time.
When a note is struck on an instrument the amplitude of the signal follows a series of level changes in relation to time. These are: Attack - The time taken for the sound to peak when initially struck Decay - The initial quieting of the sound after the initial strike Sustain - the time the note conitnues to ring for. Release - the eventual decrease to silence.
Decay - 2014 was released on: USA: 2014 (limited)
The Decay - 2009 was released on: USA: July 2009
Attack is how a note is started. Decay is how it ends.
Fussion
Nuclei undergo radioactive decay in order to release some of the "stress" in the atom. At a certain point, the nucleus of an atom gets too large to sustain all of those protons and neutrons. When the "stress" is relieved, a phenomenon called radioactive decay occurs.
plants and animals die and then decay to release carbon compound in then
Decay - 2012 II was released on: USA: 2012
This is the alpha radioactive decay.
When you struck the key the sound got loud very fast (the attack), and then it stayed about the same for a while (the sustain), maybe getting slightly softer, and then it died away fairly quickly when you released the key (the decay).
