What does ADSR stand for?

Attack, Decay, Sustain and Release.

2

What is ADSR

This is a simple type of envelope generator.
Was firstly used on analogue synths.
Continues to be popular on modern instruments.

3

Attack

The time taken for a sound to reach maximum amplitude.
e.g Drums have a short amplitude, Strings have a slow attack.

4

Amplitude

Another word for level. Can refer to sound level or electrical signal levels.

5

Decay

The progressive reduction in amplitude of a sound or electrical signal over time. The decay starts as soon as the attach phase has reached it's maximum level.

6

Sustain

Sustain determines the level which the sound will settle if a key is held down. Once the key is released the sound decay at a rate set by the release.

7

Slow decay

High sustain

8

Low sustain

Fast decay

9

Release

Time taken for a level or gain to return to normal.

10

Gain

The amount by which a circuit amplifies a signal

11

Automation

Programming adjustable parameters to operate automatically during playback and mixing.

12

Parameters

The term is used particularly for pitch, loudness, duration, and timbre, though theorists or composers have sometimes considered other musical aspects as parameters.
