web.OscillatorNode — clojure-interop/cljs-web-api 1.0.0

The OscillatorNode interface represents a periodic waveform, as a sine wave. It is an audio.AudioScheduledSourceNode audio-processing that causes a specified frequency of a given wave to be created—in a constant tone.

constructor cljs

Constructor.

The OscillatorNode() constructor of the Web Audio API creates a new web.OscillatorNode object which is an audio.AudioNode that represents a periodic waveform, like a sine wave, optionally setting the node's properties' values to match values in a specified object.

Inherits parameters from the audio.AudioNodeOptions dictionary.

\tcontext \tA reference to an audio.AudioContext. \toptions Optional \tAn object whose properties specify the initial values for the oscillator node's properties. Any properties omitted from the object will take on the default value as documented.

\t\ttype \t\tThe shape of the wave produced by the node. Valid values are 'sine', 'square', 'sawtooth', 'triangle' and 'custom'. The default is 'sine'. \t\tdetune \t\tA detuning value (in cents) which will offset the frequency by the given amount. Its default is 0. \t\tfrequency \t\tThe frequency (in hertz) of the periodic waveform. Its default is 440. \t\tperiodicWave \t\tAn arbitrary period waveform described by a web.PeriodicWave object.

detune cljs

(detune this)

Property.

An a-rate audio.AudioParam.

`var oscillator = audioCtx.createOscillator(); oscillator.detune.setValueAtTime(100, audioCtx.currentTime); // value in cents

Note: though the AudioParam returned is read-only, the value it represents is not.`

frequency cljs

(frequency this)

Property.

An a-rate audio.AudioParam.

`var oscillator = audioCtx.createOscillator(); oscillator.frequency.setValueAtTime(440, audioCtx.currentTime); // value in hertz

Note: though the AudioParam returned is read-only, the value it represents is not.`

onended cljs

(onended this)

Property.

The onended property of the web.OscillatorNode interface is to set the event handler for the ended event, which fires when tone has stopped playing.

var oscillator = audioCtx.createOscillator(); oscillator.onended = function() { ... };

set-detune! cljs

(set-detune! this val)

Property.

An a-rate audio.AudioParam.

`var oscillator = audioCtx.createOscillator(); oscillator.detune.setValueAtTime(100, audioCtx.currentTime); // value in cents

Note: though the AudioParam returned is read-only, the value it represents is not.`

set-frequency! cljs

(set-frequency! this val)

Property.

An a-rate audio.AudioParam.

`var oscillator = audioCtx.createOscillator(); oscillator.frequency.setValueAtTime(440, audioCtx.currentTime); // value in hertz

Note: though the AudioParam returned is read-only, the value it represents is not.`

set-onended! cljs

(set-onended! this val)

Property.

The onended property of the web.OscillatorNode interface is to set the event handler for the ended event, which fires when tone has stopped playing.

var oscillator = audioCtx.createOscillator(); oscillator.onended = function() { ... };

set-periodic-wave cljs

(set-periodic-wave this wave)

Method.

The setPeriodicWave() method of the web.OscillatorNode interface used to point to a web.PeriodicWave defining a periodic waveform can be used to shape the oscillator's output, when web.type custom.

OscillatorNode.setPeriodicWave(wave);

set-type! cljs

(set-type! this val)

Property.

A dom.DOMString specifying the shape of oscillator wave. The available values are:

OscillatorNode.type = type;

start cljs

(start this when)

Method.

The following example shows basic usage of an audio.AudioContext create an oscillator node. For an applied example, check out Violent Theremin demo (see app.js for relevant code).

oscillator.start(when); // start playing oscillator at the point in time specified by when

stop cljs

(stop this when)

Method.

The following example shows basic usage of an audio.AudioContext create an oscillator node. For an applied example, check out Violent Theremin demo (see app.js for relevant code).

oscillator.stop(when); // stop playing oscillator at when
