Description::
|
||
|
||
Generates a sine wave.
|
||
Uses a wavetable lookup oscillator with linear interpolation.
|
||
Frequency and phase modulation are provided for audio-rate modulation.
|
||
Technically, code::SinOsc:: uses the same implementation as link::Classes/Osc:: except that its table is fixed to be a sine wave made of code::8192:: samples.

LIST::
|
||
## link::Classes/FSinOsc:: – fast sinewave oscillator
|
||
## link::Classes/SinOscFB:: – sinewave with phase feedback
|
||
## link::Classes/PMOsc:: – phase modulation sine oscillator
|
||
## link::Classes/Klang:: – bank of sinewave oscillators
|

|
||
|
||
argument::freq
|
||
Frequency in Hertz.
|
||
Sampled at audio-rate.
|
||
|
||
argument::phase
|
||
Phase in radians.
|
||
Sampled at audio-rate.
|
||
note::phase values should be within the range +-8pi. If your phase values are larger then simply use code::.mod(2pi):: to wrap them.::
|
||
|
||
argument::mul
|
||
Output will be multiplied by this value.
|
||
|
||
argument::add
|
||
This value will be added to the output.
|
||
|
||
|
||
Examples::
|
||
|
||
code::
|
||
|
||
// create an audio-rate sine wave at 200 Hz,
|
||
// starting with phase 0 and an amplitude of 0.5
|
||
{ SinOsc.ar(200, 0, 0.5) }.play;
|
||
|
||
// modulate the frequency with an exponential ramp
|
||
{ SinOsc.ar(XLine.kr(2000, 200), 0, 0.5) }.play;
|
||
|
||
// more complex frequency modulation
|
||
{ SinOsc.ar(SinOsc.ar(XLine.kr(1, 1000, 9), 0, 200, 800), 0, 0.25) }.play;
|
||
|
||
// phase modulation (see also PMOsc)
|
||
{ SinOsc.ar(800, SinOsc.ar(XLine.kr(1, 1000, 9), 0, 2pi), 0.25) }.play;
