Vibrato

A low frequency oscillator UGen for modelling vibrato. It produces a modulating frequency value in Hertz that can be used as the frequency parameter of another UGen.

By setting more extreme settings, one can get back to the timbres of FM synthesis. One can also add in some noise to the vibrato rate and vibrato size (modulation depth) to make for a more realistic motor pattern.

The vibrato output is a waveform based on a squared envelope shape with four stages marking out 0.0 to 1.0, 1.0 to 0.0, 0.0 to -1.0, and -1.0 back to 0.0. The vibrato rate determines how quickly one moves through these stages.

Examples

// constant setting
play { SinOsc.ar(Vibrato.ar(DC.ar(400.0), 1, 0.02)) * 0.2 }

// beat and beatVar mouse control
play {
  val beat    = MouseX.kr(2.0, 100.0)
  val beatVar = MouseY.kr(0.0, 1.0)
  val freq    = Vibrato.ar(DC.ar(400.0), beat, 0.1, 1.0, 1.0, beatVar, 0.1)
  SinOsc.ar(freq) * 0.2
}

freq
fundamental frequency in Hertz. If the Vibrato UGen is running at audio rate, this must be an audio-rate input as well.
beat
vibrato rate, that is the speed of wobble in Hertz. Note that if this is set to a too low value, you may never get vibrato back, since this input is only checked at the end of a cycle.
depth
amount of vibrato frequency deviation around the fundamental, as a proportion of the fundamental.
delay
delay in seconds before vibrato is established. (init-time only)
onset
transition time in seconds from no vibrato to full vibrato after the initial delay time. (init-time only)
beatVar
random (noise) variation on the beat parameter, expressed as a proportion of beat . It can change once per cycle of vibrato.
depthVar
random (noise) variation on the depth of modulation, expressed as a proportion of depth . It can change once per cycle of vibrato. The noise affects independently the up and the down part of vibrato shape within a cycle.
iphase
initial phase of vibrato modulation, allowing starting above or below the fundamental rather than on it. (init-time only)
