This class lets you query and access the mixers that are installed on the system. <code>AudioSystem</code> includes a number of methods for converting audio data between different formats, and for translating between audio files and streams. It also provides a method for obtaining a <code><A HREF="../../../javax/sound/sampled/Line.html"><CODE>Line</CODE></A></code> directly from the <code>AudioSystem</code> without dealing explicitly with
