public abstract class JavaSoundMux
extends AbstractStreamCopyMux

Audio multiplexer base class implemented using JavaSound. This mux has the job of taking buffers passed in to process, and converting them to a stream to be read by Javasound, and then converting the stream written by Javasound into something that can be read as a track of a datasource. TODO: size is written to file headers as Integer.MAXINT, because the seeking back to the beginning and rewriting of the header is not yet implemented. JMF appears to do this with a hack, casting the SourceTransferHandler to a Seekable, and seeking the output, then rewriting. TODO: not so sure of all the open/close/connect/disconnect and which should call what when.
