/*
  Example program to read N channels of audio
  data that are streamed over an ethernet
  connection.

  by Gary P. Scavone, 2000

  This program is currently written to play
  the input data in realtime.  However, it
  is simple to replace the instance of
  RtWvOut with any other WvOut subclass.

  The class StrmWvIn sets up a socket server
  and waits for a connection.  Thus, this
  program needs to be started before the
  streaming client.  This program will
  terminate when the socket connection is
  closed.
