+/*
+  Example program to output N channels of audio
+  data over a 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 InetWvOut
+  setting to any of the other defined StkFormats.  If using tcpIn, it
+  will be necessary to change the expected data format there as well.
+
+  The class InetWvOut 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.
