Stereo Audio --> Control --> Audio conversion
Trivial example which illustrates the use of the Audio-To-Control and the Control-To-Audio converters. The stereo
input Audio signal is converted to two Control signals which are then re-converted to a stereo Audio signal. Normally,
there would be additional Control processing blocks between the converters, but these have been omitted in this
trivial example, so the output audio is identical to the original.
