Description

Generates random numbers with a user-defined limit and holds them for a period of time.

Syntax

ares randomh kmin, kmax, acps

kres randomh kmin, kmax, kcps

Performance

kmin -- minimum range limit

kmax -- maximum range limit

kcps, acps -- rate of random break-point generation

The randomh opcode is similar to randh but allows the user to set arbitrary minimum and maximum values.

Examples

Here is an example of the randomh opcode. It uses the files randomh.orc and randomh.sco.

/* randomh.orc */
; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1
  ; Choose a random frequency between 220 and 440 Hz.
  ; Generate new random numbers at 10 Hz.
  kmin = 220
  kmax = 440
  kcps = 10

  k1 randomh kmin, kmax, kcps

  printks "k1 = %f\\n", 0.1, k1
endin
/* randomh.orc */

        

/* randh.sco */
; Table #1, a sine wave.
f 1 0 16384 10 1

; Play Instrument #1 for one second.
i 1 0 1
e
/* randh.sco */

        

Its output should include lines like:

k1 = 220.000000
k1 = 414.232056
k1 = 284.095184
