class:: Ramp
summary:: Break a continuous signal into line segments
related:: Classes/Lag, Classes/VarLag, Classes/Slew
categories:: UGens>Filters>Linear
Description::
Break a continuous signal into linearly interpolated segments with specific durations.
Feeding Ramp with noise is similar to link::Classes/LFNoise1::
code::
Ramp.kr(WhiteNoise.kr(1),0.5)
::
is equal to:
code::
LFNoise1.kr(1 / 0.5)
::
For smoothing out control signals, take a look at link::Classes/Lag:: and link::Classes/VarLag::
classmethods::
method::ar, kr
argument::in
The input signal.
argument::lagTime
segment duration in seconds.
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
s.boot;
(
// used to lag pitch
{
SinOsc.ar( // sine wave
Ramp.kr( // lag the modulator
LFPulse.kr(4, 0, 0.5, 50, 400), // frequency modulator
Line.kr(0, 1, 15) // modulate lag time
),
0, // phase
0.3 // sine amplitude
)
}.scope;
)
// Compare
(
var pulse;
{
pulse = LFPulse.kr(8.772);
Out.kr(0,[Ramp.kr(pulse, 0.025), Lag.kr(pulse, 0.025), pulse]);
}.play;
s.scope(3, bufsize: 44100, rate: \control, zoom: 40);
)
