 // Notes about generated waveforms:
 //
 // QUESTION: Why does the wave shape not look like the exact shape (sharp edges)?
 // ANSWER: Because a shape with sharp edges has infinitely high frequency content.
 // Since a digital audio signal must be band-limited based on the nyquist frequency (half the sample-rate)
 // in order to avoid aliasing, this creates more rounded edges and "ringing" in the
 // appearance of the waveform.  See Nyquist-Shannon sampling theorem:
 // http://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem
 //
 // QUESTION: Why does the very end of the generated signal appear to get slightly weaker?
