/******************************************/
/*
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.
