## jitter2

jitter2 — Generates a segmented line with user-controllable random segments.

## Description

Generates a segmented line with user-controllable random segments.

## Syntax

    kout jitter2 ktotamp, kamp1, kcps1, kamp2, kcps2, kamp3, kcps3

## Performance

ktotamp -- Resulting amplitude of jitter2

kamp1 -- Amplitude of the first jitter component

kcps1 -- Speed of random variation of the first jitter component (expressed in cps)

kamp2 -- Amplitude of the second jitter component

kcps2 -- Speed of random variation of the second jitter component (expressed in cps)

kamp3 -- Amplitude of the third jitter component

kcps3 -- Speed of random variation of the third jitter component (expressed in cps)

jitter2 also generates a segmented line such as jitter, but in this case the result is similar to the sum of three randi opcodes, each one with a different amplitude and frequency value (see randi for more details), that can be varied at k-rate. Different effects can be obtained by varying the input arguments.

jitter2 can be used to make more natural and “analog-sounding” some static, dull sound. For best results, it is suggested to keep its amplitude moderate.

## Examples

Here is an example of the jitter2 opcode. It uses the file jitter2.csd.
