## vibr

vibr — Easier-to-use user-controllable vibrato.

## Description

Easier-to-use user-controllable vibrato.

## Syntax

    kout vibr kAverageAmp, kAverageFreq, ifn

## Initialization

ifn -- Number of vibrato table. It normally contains a sine or a triangle wave.

## Performance

kAverageAmp -- Average amplitude value of vibrato

kAverageFreq -- Average frequency value of vibrato (in cps)

vibr is an easier-to-use version of vibrato. It has the same generation-engine of vibrato, but the parameters corresponding to missing input arguments are hard-coded to default values.

## Examples

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

Example 544. Example of the vibr opcode.
