+    @brief Generate Pink Noise using Gardner method, and make "waves". Provides an example of how to
+           post stuff to/from the audio callback using lock-free FIFOs implemented by the PA ringbuffer.
+
+    Optimization suggested by James McCartney uses a tree
+    to select which random value to replace.
+<pre>
+    x x x x x x x x x x x x x x x x
+    x   x   x   x   x   x   x   x
+    x       x       x       x
+     x               x
+       x
+</pre>
+    Tree is generated by counting trailing zeros in an increasing index.
+    When the index is zero, no random number is selected.
