class:: BufWr
summary:: Buffer writing oscillator.
related:: Classes/BufRd
categories:: UGens>Buffer
Description::
Write to a buffer at an index.
note:: BufWr (in difference to link::Classes/BufRd:: ) does not do multichannel expansion, because input is an array. ::
classmethods::
private:: categories
method::ar, kr
argument::inputArray
Input UGens (channelArray).
argument::bufnum
The index of the buffer to use.
argument::phase
Modulateable index into the buffer (has to be audio rate).
Warning:: The phase argument only offers precision for addressing 2**24 samples (about 6.3 minutes at 44100Hz) ::
argument::loop
1 means true, 0 means false. This is modulateable.
instancemethods::
private:: checkInputs
Examples::
code::
(
// allocate a buffer for writinig into
s = Server.local;
s.sendMsg("/b_alloc", 0, 44100 * 2);
)
//write into the buffer with a BufWr
(
y = { arg rate=1;
var in;
in = SinOsc.ar(LFNoise1.kr(2, 300, 400), 0, 0.1);
BufWr.ar(in, 0, Phasor.ar(0, BufRateScale.kr(0) * rate, 0, BufFrames.kr(0)));
0.0 //quiet
}.play;
)
//read it with a BufRd
(
x = { arg rate=1;
BufRd.ar(1, 0, Phasor.ar(0, BufRateScale.kr(0) * rate, 0, BufFrames.kr(0)))
}.play(s);
)
x.set(\rate, 5);
y.set(\rate, 2.0.rand);
x.set(\rate, 2);
