+   Linearly Interpolating Delay Line
+   Object by Perry R. Cook 1995-96.
+   Added methods by Julius Smith, 2000.
+
+   This one uses a delay line of maximum
+   length specified on creation, and
+   linearly interpolates fractional
+   length.  It is designed to be more
+   efficient if the delay length is not
+   changed very often.
