# cauchy

cauchy -- Cauchy distribution random number generator.

## Description

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

## Syntax

ar cauchy kalpha

ir cauchy kalpha

kr cauchy kalpha

## Performance

kalpha -- controls the spread from zero (big kalpha = big spread). Outputs both positive and negative numbers.

For more detailed explanation of these distributions, see:

1. C. Dodge - T.A. Jerse 1985. Computer music. Schirmer books. pp.265 - 286

2. D. Lorrain. A panoply of stochastic cannons. In C. Roads, ed. 1989. Music machine . Cambridge, Massachusetts: MIT press, pp. 351 - 379.

## Examples

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

Example 1. Example of the cauchy opcode.

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

    ; Instrument #1.
    instr 1
      ; Generate a random number, spread from 10.
      ; kalpha = 10

      i1 cauchy 10

      print i1
    endin
    /* cauchy.orc */

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

Its output should include lines like:

    instr 1:  i1 = -0.106
