+ * A format conversion provider provides format conversion services
+ * from one or more input formats to one or more output formats.
+ * Converters include codecs, which encode and/or decode audio data,
+ * as well as transcoders, etc.  Format converters provide methods for
+ * determining what conversions are supported and for obtaining an audio
+ * stream from which converted data can be read.
+ * <p>
+ * The source format represents the format of the incoming
+ * audio data, which will be converted.
+ * <p>
+ * The target format represents the format of the processed, converted
+ * audio data.  This is the format of the data that can be read from
+ * the stream returned by one of the <code>getAudioInputStream</code> methods.
