<hr><a name="_details"></a><h2>Detailed Description</h2>
STK internet streaming input class.
<p>
This protected Wvin subclass can read streamed data over a network via a TCP socket connection. The data is assumed in big-endian, or network, byte order.
<p>
TcpWvIn supports multi-channel data in interleaved format. It is important to distinguish the <a class="el" href="classTcpWvIn.html#a5">tick</a>() methods, which return samples produced by averaging across sample frames, from the <a class="el" href="classTcpWvIn.html#a8">tickFrame</a>() methods, which return pointers to multi-channel sample frames. For single-channel data, these methods return equivalent values.
<p>
This class starts a socket server, which waits for a single remote connection. The default data type for the incoming stream is signed 16-bit integers, though any of the defined STK_FORMATs are permissible.
