	<h3>Functions</h3>
	<p class=func><span class=keyword>begin</span>(waveform);</p>
	<p class=desc>Configure the waveform type to create.
	</p>
	<p class=func><span class=keyword>begin</span>(level, frequency, waveform);</p>
	<p class=desc>Output a waveform, and set the amplitude and frequency.
	</p>
	<p class=func><span class=keyword>frequency</span>(freq);</p>
	<p class=desc>Change the frequency.
	</p>
	<p class=func><span class=keyword>amplitude</span>(level);</p>
	<p class=desc>Change the amplitude.  Set to 0 to turn the signal off.
	</p>
	<p class=func><span class=keyword>phase</span>(angle);</p>
	<p class=desc>
		Cause the generated waveform to jump to a specific point within
		its cycle.  Angle is from 0 to 360 degrees.  When multiple objects
		are configured,
		<a href="http://www.pjrc.com/teensy/td_libs_AudioProcessorUsage.html" target="_blank">AudioNoInterrupts()</a>
		should be used to guarantee all new settings take effect together.
	</p>
	<p class=func><span class=keyword>pulseWidth</span>(amount);</p>
	<p class=desc>Change the width (duty cycle) of the pulse.</p>
	<p class=func><span class=keyword>arbitraryWaveform</span>(array, maxFreq);</p>
	<p class=desc>
		Configure the waveform to be used with WAVEFORM_ARBITRARY.  Array
		must be an array of 256 samples.  Currently, the data is used
		without any filtering, which can cause aliasing with frequencies
		above 172 Hz.  For higher frequency output, you must bandwidth
		limit your waveform data.  Someday, "maxFreq" will be used to
		do this automatically.
