DELAY -- delay an input signal with feedback
in RTcmix/insts/std

quick syntax:
DELAY(outsk, insk, indur, amp, delaytime, feedback, ringdowndur[, inputchan, pan])

   DELAY - delay instrument with feedback

      p0 = output start time
      p1 = input start time
      p2 = input duration
      p3 = amplitude multiplier
      p4 = delay time
      p5 = delay feedback (i.e., regeneration multiplier) [0-1]
      p6 = ring-down duration
      p7 = input channel [optional, default is 0]
      p8 = pan (in percent-to-left form: 0-1) [optional, default is 0] 

   p3 (amplitude), p4 (delay time), p5 (feedback) and p8 (pan) can receive
   dynamic updates from a table or real-time control source.

   If an old-style gen table 1 is present, its values will be multiplied
   by the p3 amplitude multiplier, even if the latter is dynamic.

   The point of the ring-down duration parameter is to let you control
   how long the delay will sound after the input has stopped.  Too short
   a time, and the sound may be cut off prematurely.

Older Documentation:


DELAY is a simple, regenerating delay instrument. It has parameters for regeneration (amount of feedback) and for ring-down time, so that the delay decays naturally.

Syntax:


makegen(1, 24, 1000, t0, a0, t1, a1) /* amplitude envelope in time/amplitude pairs */

DELAY(outskip, inskip, duration, amplitude, delaytime, regeneration, ringdown, inchan, spread) /* regeneration should be less than 1 */

in comment form:

/* DELAY: regenerating delay instrument
*
*  p0 = output start time
*  p1 = input start time
*  p2 = input duration
*  p3 = amplitude multiplier
*  p4 = delay time
*  p5 = regeneration multiplier (< 1.0!)
*  p6 = ring-down duration
*  p7 = input channel number 
*  p8 = stereo spread (0.0-1.0) 
*  assumes function slot 1 is the amplitude envelope

Another score, using real-tine audio input:

load("DELAY")
rtinput("AUDIO", "MIC")
makegen(1, 24, 1000, 0,1, 100,1)
DELAY(0, 0, 14, 1.0, .078, 0.8, 3.5, 0, 0.1)
