Abbreviation for Attack, Decay, Sustain, and Release. These are the four parameters found on a basic synthesizer envelope generator. An envelope generator is sometimes called a transient generator. The Attack, Decay, and Release parameters are rate or time controls. Sustain is a level. When a key is pressed, the envelope generator will begin to rise to its full level at the rate set by the attack parameter, upon reaching peak level it will begin to fall at the rate set by the decay parameter to the level set by the sustain control. The envelope will remain at the sustain level as long as the key is held down. Whenever a key is released, it will return to zero at the rate set by the release parameter.
A type of envelope generator. It has four stages - the attack of the note where it build up to its initial volume peak when you press the key, the decay where it goes back down in volume to the sustain level where it stays until the player releases the key and it fades out.
a type of envelope and is used to dynamicaly control various synthesis functions
Attack, Decay, Sustain and Release are the four stages of an envelope that describe the shape of a sound over time. Attack represents the time the sound takes to rise from an initial value of zero to its maximum level. Decay is the time for the initial falling off to the sustain level. Sustain is the time during which it remains at this level. Release is the time it takes to move from the sustain to its final level. Release typically begins when a note is let up. In most sound generators, the time and the value reached are programmable.
(Attack, Decay, Sustain and Release)Module which is present in all synthesizers, enabling them to simulate the manner in which instruments make their sound. It can, for example, set up an attack like a piano's (short, sharp), and appropriate decay time sustain and release switch, which fixes the end of the notes.
The shape of the amplitude of a signal over time; attack: the beginning of a soundthe first part of an amplitude envelope; decay: the part of an amplitude envelope between the maximum volume of the attack and sustain; sustain: to maintain a consistent volumethe section of an amplitude envelope at which the sound maintains a consistent volume; release: the final segment of an amplitude envelopethe time the sound takes to fall to zero from the sustain level after a key is released.
The shape of the amplitude of a signal over time. Attack refers to the beginning of a sound, the first part of an amplitude envelope. Decay refers to the part of an amplitude envelope between the maximum volume of the attack and sustain. Sustain means the part at which the sound maintains a consistent volume. Release refers to the final segment, the time the sound takes to fall to zero from the sustain level after a key is released.
Attack Decay Sustain Release - the four control elements of an envelope.
"Attack/Decay/Sustain/Release." The four properties of a traditional audio envelope.
An acronym for Attack, Decay, Sustain and Release, referring to the dynamic characteristics common to all sounds. In an analog synthesizer the ADSR control provides control over these parameters and considerable sound modifying possibilities.
