-// This delays the input signal for an amount of time. The time
-// specification can be any number greater or equal zero.
-// The delay is constant during the calculation, that means it
-// can't be modified. This saves computing time as no interpolation is
-// done, and is useful for recursive structures. Actually it can be
-// modified, but without interpolation it won't sound too good. See
-// the description for Synth_DELAY.
