Editing Unit generator (section)

== Examples ==
A simple unit generator called OSC could generate a sinusoidal waveform of a specific frequency (given as an input or argument to the [[function (programming)|function]] or [[class (computer science)|class]] that represents the unit generator). ENV could be a unit generator that delineates a breakpoint function. Thus ENV could be used to drive the [[amplitude]] [[ADSR_envelope|envelope]] of the oscillator OSC through the equation OSC*ENV. Unit generators often use predefined arrays of values for their functions (which are filled with [[waveform]]s or other [[shape]]s by calling a specific generator function).

In the [[SuperCollider]] language, the .ar [[method (computer science)|method]] in the SinOsc class<ref>{{Cite web |title=SinOsc {{!}} SuperCollider 3.13.0 Help |url=https://docs.supercollider.online/Classes/SinOsc.html |access-date=2024-11-03 |website=docs.supercollider.online}}</ref> [[Inheritance (object-oriented programming)|inherits]] methods from an overarching unit generator class (UGen)<ref name=supercollider-ugen /> that generates a [[sine wave]].  The example below makes a sine wave at frequency 440, phase 0, and amplitude 0.5.
