/*
  Example program to output N channels of audio
  data over a TCP network socket connection.

  by Gary P. Scavone, 2000

  This program will load a specified WAV,
  SND, AIFF, STK RAW, or MAT-file formatted
  file.  The output data format is set for
  signed 16-bit integers.  However, it is
  easy to change the TcpWvOut setting to
  any of the other defined STK_FORMATs.
  If using tcpIn, it will be necessary to
  change the expected data format there
  as well.

  The class StrmWvOut first attempts to
  establish a socket connection to a socket
  server running on port 2006.  Therefore,
  this program needs to be started AFTER the
  streaming server.
