+/*! \class Whistle
+    \brief STK police/referee whistle instrument class.
+
+    This class implements a hybrid physical/spectral
+    model of a police whistle (a la Cook).
+
+    Control Change Numbers: 
+       - Noise Gain = 4
+       - Fipple Modulation Frequency = 11
+       - Fipple Modulation Gain = 1
+       - Blowing Frequency Modulation = 2
+       - Volume = 128
+
+    by Perry R. Cook  1996 - 2002.
