<hr><a name="_details"></a><h2>Detailed Description</h2>
STK internet streaming output class.
<p>
This protected <a class="el" href="classWvOut.html">WvOut</a> subclass can stream data over a network via a TCP socket connection. The data is converted to big-endian byte order, if necessary, before being transmitted.<p>
TcpWvOut supports multi-channel data in interleaved format. It is important to distinguish the <a class="el" href="classTcpWvOut.html#a7">tick()</a> methods, which output single samples to all channels in a sample frame, from the <a class="el" href="classTcpWvOut.html#a9">tickFrame()</a> method, which takes a pointer to multi-channel sample frame data.<p>
This class connects to a socket server, the port and IP address of which must be specified as constructor arguments. The default data type is signed 16-bit integers but any of the defined STK_FORMATs are permissible.<p>
by Perry R. Cook and Gary P. Scavone, 1995 - 2002.
