+/**
+ * A mixer is an audio device with one or more lines.  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>{@link SourceDataLine}</code>,
+ * and the latter, <code>{@link TargetDataLine}</code>.  <code>{@link Port}</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>{@link Clip}</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.
