class:: Splay
summary:: Splay spreads an array of channels across the stereo field
categories:: UGens>Multichannel>Panners
related:: Classes/SplayAz, Classes/SplayZ
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
classmethods::
method:: ar, kr
argument:: inArray
The array of channels to be distributed over the two stereo pairs
argument:: spread
For spread = 0, all channels end up in the centre, for 1, they have maximum distribution
argument:: level
An amplitude multiplier for all channels
argument:: center
Shift the centre of the distribution.
argument:: levelComp
method:: arFill
In analogy to Mix:arFill, this method takes a function that produces the channels. The counting index is passed to it.
argument:: n
Number of channels
argument:: function
Function to return each channel
argument:: spread
For spread = 0, all channels end up in the centre, for 1, they have maximum distribution
argument:: level
An amplitude multiplier for all channels
argument:: center
Shift the centre of the distribution.
argument:: levelComp
examples::
code::
(
x = { arg spread=1, level=0.2, center=0.0;
Splay.ar(
SinOsc.ar( { |i| LFNoise2.kr(1).exprange(200, 4000) } ! 10),
spread,
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
x.set(\spread, 0.5, \center, 0.5);
// 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)) },
spread,
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;
)
