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.<P><DL><DT><B>Since: </B><DD>1.3</DD></DL><HR><P><!-- ======== INNER
