trirand

trirand --  Linear distribution random number generator.

Description

Linear distribution random number generator. This is an x-class noise generator.

Syntax

ar trirand krange

ir trirand krange

kr trirand krange

Performance

krange -- the range of the random numbers (-krange to +krange).

For more detailed explanation of these distributions, see:

Examples

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

Example 1. Example of the trirand opcode.

/* trirand.orc */
/* Written by Kevin Conder */
; Initialize the global variables.
sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

; Instrument #1.
instr 1
  ; Generate a random number between -1 and 1.
  ; krange = 1

  i1 trirand 1

  print i1
endin
/* trirand.orc */
        
/* trirand.sco */
/* Written by Kevin Conder */
; Play Instrument #1 for one second.
i 1 0 1
e
/* trirand.sco */
        
Its output should include lines like this:
instr 1:  i1 = 7506.261
