<div class="description">
<p>Generate a sine and cosine table simultaneously and extremely quickly. Based on research by Franky of scene.at</p>
<p>&lt;p&gt;
The parameters allow you to specify the length, amplitude and frequency of the wave. Once you have called this function
you should get the results via getSinTable() and getCosTable(). This generator is fast enough to be used in real-time.
