<p>STK sinusoid oscillator class. </p>
<p>This class computes and saves a static sine "table" that can be shared by multiple instances. It has an interface similar to the WaveLoop class but inherits from the <a class="el" href="classstk_1_1Generator.html" title="STK abstract unit generator parent class.">Generator</a> class. Output values are computed using linear interpolation.</p>
<p>The "table" length, set in <a class="el" href="SineWave_8h_source.html">SineWave.h</a>, is 2048 samples by default.</p>
