It need not be designed for mixing audio signals. A mixer that actually mixes audio has multiple input (source) lines and at least one output (target) line. The former are often instances of classes that implement <code><A HREF="../../../javax/sound/sampled/SourceDataLine.html"><CODE>SourceDataLine</CODE></A></code>, and the latter, <code><A HREF="../../../javax/sound/sampled/TargetDataLine.html"><CODE>TargetDataLine</CODE></A></code>. <code><A HREF="../../../javax/sound/sampled/Port.html"><CODE>Port</CODE></A></code> objects, too, are either source lines or target lines. A mixer can accept prerecorded, loopable sound as input, by having some of its source lines be instances of objects that implement the <code><A HREF="../../../javax/sound/sampled/Clip.html"><CODE>Clip</CODE></A></code> interface. <p> Through methods of the <code>Line</code> interface, which <code>Mixer</code> extends, a mixer might provide a set of controls that are global to the mixer. For example, the mixer can have a master gain control. These global controls are distinct from the controls belonging to each of the mixer's individual lines. <p> Some mixers, especially those with internal digital mixing capabilities, may provide additional capabilities by implementing the <code>DataLine</code> interface. <p> A mixer can support synchronization of its lines. When one line in a synchronized group is started or stopped, the other lines in the group automatically start or stop simultaneously with the explicitly affected one.<P><DL><DT><B>Since:
