<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><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.
