It need not be 0N/A * designed for mixing audio signals. A mixer that actually mixes audio 0N/A * has multiple input (source) lines and at least one output (target) line. 0N/A * The former are often instances of classes that implement 0N/A * <code>{@link SourceDataLine}</code>, 0N/A * and the latter, <code>{@link TargetDataLine}</code>. <code>{@link Port}</code> 0N/A * objects, too, are either source lines or target lines. 0N/A * A mixer can accept prerecorded, loopable sound as input, by having 0N/A * some of its source lines be instances of objects that implement the 0N/A * <code>{@link Clip}</code> interface. 0N/A * Through methods of the <code>Line</code> interface, which <code>Mixer</code> extends, 0N/A * a mixer might provide a set of controls that are global to the mixer. For example, 0N/A * the mixer can have a master gain control. These global controls are distinct 0N/A * from the controls belonging to each of the mixer's individual lines. 0N/A * Some mixers, especially 0N/A * those with internal digital mixing capabilities, may provide 0N/A * additional capabilities by implementing the <code>DataLine</code> interface. 0N/A * A mixer can support synchronization of its lines. When one line in 0N/A * a synchronized group is started or stopped, the other lines in the group 0N/A * automatically start or stop simultaneously with the explicitly affected one. 0N/A * @author Kara Kytle 0N/A * Obtains information about this mixer, including the product's name, 0N/A * version, vendor, etc. 0N/A * @return a mixer info object that describes this mixer 0N/A * Obtains information about the set of source lines supported 0N/A * Some source lines may only be available when this mixer is open. 0N/A * @return array of <code>Line.Info</code> objects representing source lines 0N/A * for this mixer.

For example, if the info 0N/A * object represents a speaker 0N/A * port, and the mixer supports exactly one speaker port, this method 0N/A * should return 1.
