## cauchyi

cauchyi — Cauchy distribution random number generator with interpolation.

## Description

Cauchy distribution random number generator with controlled interpolation between values. This is an x-class noise generator.

## Syntax

    ares cauchyi klambda, xamp, xcps

    ires cauchyi klambda, xamp, xcps

    kres cauchyi klambda, xamp, xcps

## 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.

xamp -- range over which random numbers are distributed.

xcps -- the frequency which new random numbers are generated.

## Examples

Here is an example of the cauchyi opcode. It uses the file cauchyi.csd.
