	<h3>Notes</h3>
	<p>Cross fading can be built with 2 fade objects fed into a mixer.
		When one fade object is off (fully faded out) and the other on
		(fully faded in), if both are started at the same moment for the
		same time duration, their signal gains always add to 1.0.  This
		allows 2 fade objects to work together for a smooth transition
		between a pair of signals.
	</p>
	<p><a href="http://www.pjrc.com/teensy/td_libs_AudioProcessorUsage.html" target="_blank">AudioNoInterrupts()</a>
		should be used when changing
		settings on multiple objects, so all changes always take effect
		at the same moment.
