<p>Generates a sine wave. Uses a wavetable lookup oscillator with linear interpolation. Frequency and phase modulation are provided for audio-rate modulation. Technically, <code>SinOsc</code> uses the same implementation as <a href="./../Classes/Osc.html">Osc</a> except that its table is fixed to be a sine wave made of <code>8192</code> samples.<h3><a class='anchor' name='Other%20sinewaves%20oscillators'>Other sinewaves oscillators</a></h3>
