ADSR

This node represents an ADSR envelope.

An envelope is a term used to describe the evolution of a sound in a music sample. Envelopes are typically fed through and envelope generator that defines when and how a sound should change while the envelope defines the modulation of the sound.

The ADSR envelope is named after its four characteristics : Attack, Decay, Sustain, Release.

The input of the node is binary meaning that 0 is understood as LOW while any other value is understood as HIGH.

*When setting the parameters of the node take care to factor in the refresh time of the graph (8-16 ms)
In other words, setting values under 20ms will not produce the desired outcome.

Properties

• Attack Level : The maximum value to reach at the attack phase.
  Default : 1.0

• Attack : The time it takes to reach full capacity in milliseconds.
  Default : 100

• Decay : The time it takes to go from attack level to sustain level in milliseconds.
  Default : 100

• Release : The time it takes to go from sustain level back to nothing after release, in milliseconds.
  Default : 100

• Sustain Level : The nominal value to reach.
  Default : 0.5

Example

In this example :

• Attack level : 2.0
• Attack, ms : 250
• Decay, ms : 250
• Release, ms : 1000
• Sustain level : 1.0
