+    This class is based on some of the famous
+    Stanford/CCRMA reverbs (NRev, KipRev), which
+    were based on the Chowning/Moorer/Schroeder
+    reverberators using networks of simple allpass
+    and comb delay filters.  This class implements
+    two series allpass units and two parallel comb
+    filters.
