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;
)
