## javax.sound.sampled
Class Control

    java.lang.Object
      javax.sound.sampled.Control

Direct Known Subclasses:
  BooleanControl, CompoundControl, EnumControl, FloatControl

public abstract class Control
extends Object

`Lines` often have a set of controls, such as gain and pan, that affect the audio signal passing through the line. Java Sound's `Line` objects let you obtain a particular control object by passing its class as the argument to a `getControl` method.

Because the various types of controls have different purposes and features, all of their functionality is accessed from the subclasses that define each kind of control.

Since:
  1.3

  `Line.getControls()`, `Line.isControlSupported(javax.sound.sampled.Control.Type)`
