class:: K2A
summary:: Control to audio rate converter.
related:: Classes/A2K
categories::  UGens>Conversion


Description::

To be able to play a control rate UGen into an audio rate UGen,
sometimes the rate must be converted. K2A converts via linear
interpolation.


classmethods::

method::ar

argument::in
The input signal.

Examples::

code::
{ K2A.ar(WhiteNoise.kr(0.3)) }.scope;


// compare:
(
{
	[
		K2A.ar(WhiteNoise.kr(0.3)),
		WhiteNoise.ar(0.3)
	]
}.scope;
)

(
{
	var freq, blockSize, sampleRate;
	blockSize = s.options.blockSize; // usually 64
	sampleRate = s.sampleRate;
	freq = MouseX.kr(0.1, 40, 1) / blockSize * sampleRate;
	[
		K2A.ar(LFNoise0.kr(freq)),
		LFNoise0.ar(freq)
	] * 0.3
}.scope;
)
