+	<p class=desc>Set the frequency, from 0 to 22000.  Very low values may
+		be used to create a LFO (Low Frequency Oscillator) for objects
+		with modulation signal inputs.

+	<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>
+	<h3>Notes</h3>
+	<p>An 11th order Taylor series approximation is used to generate
+		a very accurate sine wave.  At least the upper 25 bits are believe
+		to be perfect.  This is mainly intended for testing 24 bit codec chips!</p>
