/*! \class FileWvOut
\brief STK audio file output class.
This class inherits from WvOut. It provides a "tick-level"
interface to the FileWrite class.
FileWvOut writes samples to an audio file and supports
multi-channel data. It is important to distinguish the tick()
method that outputs a single sample to all channels in a sample
frame from the overloaded one that takes a reference to an
StkFrames object for multi-channel and/or multi-frame data.
See the FileWrite class for a description of the supported audio
file formats.
Currently, FileWvOut is non-interpolating and the output rate is
always Stk::sampleRate().
