|
|
STK audio output abstract base class.
|
|
<p>
|
|
This class provides common functionality for a variety of audio data output subclasses.<p>
|
|
WvOut supports multi-channel data. It is important to distinguish the <a class="el" href="classWvOut.html#a6">tick()</a> methods, which output single samples to all channels in a sample frame, from the <a class="el" href="classWvOut.html#a8">tickFrame()</a> methods, which take a pointer or reference to multi-channel sample frame data.<p>
|
|
Both interleaved and non-interleaved data is supported via the use of <a class="el" href="classStkFrames.html">StkFrames</a> objects.<p>
|
|
Currently, WvOut is non-interpolating and the output rate is always <a class="el" href="classStk.html#e0">Stk::sampleRate()</a>.<p>
