Envelopes ramp amplitude, frequency or any other parameter over time.
|
|
<a href="http://tonejs.org/docs/#Envelope">Tone.Envelope</a> and the classes that extend it
|
|
implement an <a href="https://en.wikipedia.org/wiki/Synthesizer#ADSR_envelope" target="_blank">ADSR</a> envelope type
|
|
which splits its ramp into four distinct phases: Attack, Decay, Sustain, Release.
