## 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.
