+/*
+  Example program to read N channels of audio data that are streamed
+  over a network connection.
+
+  by Gary P. Scavone, 2000
+
+  NOTE: This program makes use of blocking audio input/output
+  routines.  On systems where the underlying audio API is based on a
+  callback scheme (Macintosh OS-X, Windows ASIO, and Linux JACK),
+  these routines are not fully robust (over/underruns can happen with
+  some frequency).  See the STK tutorial for example programs using
+  callback schemes and/or visit the RtAudio tutorial page
+  (http://music.mcgill.ca/~gary/rtaudio/) for more information.
+
+  This program is currently written to play the input data in
+  realtime.  However, it is simple to replace the instance of RtWvOut
+  with FileWvOut for writing to a soundfile.
+
+  The streamed data format is assumed to be signed 16-bit integers.
+  However, both InetWvIn and InetWvOut can be initialized to
+  read/write any of the defined StkFormats.
+
+  The class InetWvIn sets up a socket server and waits for a
+  connection.  Therefore, this program needs to be started before the
+  streaming client.  This program will terminate when the socket
+  connection is closed.
