What is an envelope in synthesis?
An Envelope is simply a table of data points that is output over a specified period of time. The output is triggered by a user event, typically a new note or key press. There is usually some sort of sustain stage that will dictate the overall duration of the envelope based on how long a key is pressed.
What is ADSR in sound?
ADSR stands for the envelope's four stages of modulation: attack, decay, sustain, and release. These stages control the level of the sound from the moment you press a key or advance a music sequencer. In music production and sound design, ADSR envelopes are typically used to control the loudness of a sound.
What are the 4 parameters in a sound envelope?
Envelope generators, which allow users to control the different stages of a sound, are common features of synthesizers, samplers, and other electronic musical instruments. The most common form of envelope generator is controlled with four parameters: attack, decay, sustain and release (ADSR).
What does sustain control in an ADSR envelope?
Envelope controls
Sustain: Sets the steady amplitude level produced when a key is held down.
