# Splay : UGen : AbstractFunction : Object

Splay spreads an array of channels across the stereo field
Source: Splay.sc

## Description

Splay spreads an array of channels across the stereo field. Optional arguments are spread and center, and equal power levelCompensation. The formula for the stereo position is ((0 .. (n - 1)) * (2 / (n - 1)) - 1) * spread + center

## Class Methods

### Splay.kr(inArray, spread: 1, level: 1, center: 0, levelComp: true)

#### Arguments:

 inArray The array of channels to be distributed over the two stereo pairs spread For spread = 0, all channels end up in the centre, for 1, they have maximum distribution level An amplitude multiplier for all channels center Shift the centre of the distribution. levelComp

### Splay.arFill(n, function, spread: 1, level: 1, center: 0, levelComp: true)

In analogy to Mix:arFill, this method takes a function that produces the channels. The counting index is passed to it.

#### Arguments:

 n Number of channels function Function to return each channel spread For spread = 0, all channels end up in the centre, for 1, they have maximum distribution level An amplitude multiplier for all channels center Shift the centre of the distribution. levelComp

## Examples

```(
x = { arg spread=1, level=0.2, center=0.0;
Splay.ar(
SinOsc.ar( { |i| LFNoise2.kr(1).exprange(200, 4000) } ! 10),
level,
center
);
}.play;
)

x.set(\spread, 1,   \center, 0);  // full stereo
x.set(\spread, 0.5, \center, 0);  // less wide
x.set(\spread, 0,   \center, 0);  // mono center
// spread from center to right
x.set(\spread, 0,   \center, -1); // all left
x.set(\spread, 1,   \center, 0);  // full stereo

// the a similar example written with arFill:
(
x = { arg spread=1, level=0.2, center=0.0;
Splay.arFill(10,
{ |i| SinOsc.ar( LFNoise2.kr( rrand(10, 20), 200, i + 3 * 100))  },
level,
center
);
}.play;
)

// with mouse control
(
x = { var src;
src = SinOsc.ar( { |i| LFNoise2.kr( rrand(10, 20), 200, i + 3 * 100) } ! 10);
Splay.ar(src, MouseY.kr(1, 0), 0.2, MouseX.kr(-1, 1));
}.play;
)```
