-// This delays the input signal for an amount of time. The time
-// specification must be between 0 and 1 for a delay between 0 seconds
-// and 1 second.
-//
-// This kind of delay may not be used in feedback structures. This is
-// because it's a variable delay. You can modify it's length while it
-// is running, and even set it down to zero. But since in a feedback
-// structure the own output is needed to calculate the next samples, a
-// delay whose value could drop to zero during synthesis could lead to
-// a stall situation.
-//
-// Use CDELAYs in that setup, perhaps combine a small constant delay
-// (of 0.001 seconds) with a flexible delay.
-//
-// You can also combine a CDELAY and a DELAY to achieve a variable
-// length delay with a minimum value in a feedback loop. Just make
-// sure that you have a CDELAY involved.
