TITLE:: FluidStats

|
summary:: Rolling mean and standard devication on kr inputs
|
|
categories:: Libraries>FluidCorpusManipulation

related:: Classes/FluidBufStats, Classes/FluidStandardize
|
|
|
|
DESCRIPTION::
|
|
Computes the rolling mean and sample standard deviation over a given window for multichannel kr inputs.
|
|
|
|
This UGen does not perform multichannel expansion because (like link::Classes/BufWr::) it takes an array as input.
|
|
|
|
CLASSMETHODS::
|
|
|
|
METHOD:: kr
|
|
Run the UGen
|
|
|
|
ARGUMENT:: inputsArray
|
|
An array (or just one) kr input stream.
|
|
|
|
ARGUMENT:: size
|
|
The size of the history window to use
|
|
|
|
returns:: A 2D array of kr outputs code::[[means][standard deviations]]::

EXAMPLES::

|
|
code::
|
|
(
|
|
~gaussianNoise = { |a,b|
|
|
var mag = (-2 * a.abs.log).sqrt;
|
|
var f = 2 * pi * b.abs;
|
|
[mag * f.cos, mag * f.sin]
|
|
}

|
|
|
|

|
|
{
|
|
var src = ~gaussianNoise.value(WhiteNoise.kr,WhiteNoise.kr);
|
|
var stats = FluidStats.kr(src,20);
|
|
stats[0].poll(label:'means');
|

stats[1].poll(label:'standard deviations');
