/*
  Example program to output N channels of audio
  data over an ethernet socket connection.

  by Gary P. Scavone, 2000

  This program is currently written to load
  a WAV file for streaming.  However, it is
  simple to replace the instance of WavWvIn
  with any other WvIn subclass.

  The class StrmWvOut first attempts to
  establish a socket connection to a socket
  server running on port 2005.  Thus, this
  program needs to be started after the
  streaming server.
