ActionScript 3.0 Library like [Web Audio API](http://webaudio.github.io/web-audio-api/)

  

## API

### AudioContext

  

* [AudioContext](http://webaudio.github.io/web-audio-api/#the-audiocontext-interface)

  

The 1st, it is required the instance of AudioContext is created.

  

    import audioapi.AudioContext;

    var context:AudioContext = new AudioContext(stage.frameRate);

    trace(context.sampleRate);   // 44100 Hz

    trace(context.currentTime);  // http://webaudio.github.io/web-audio-api/#the-audiocontext-interface

    trace(context.destination);  // the instance of AudioDestinationNode (http://webaudio.github.io/web-audio-api/#the-audiodestinationnode-interface)

  

### OscillatorNode

  

* [OscillatorNode](http://webaudio.github.io/web-audio-api/#the-oscillatornode-interface)

  

The instance of OscillatorNode is created by createOscillator method.

  

    import audioapi.AudioContext;

    import audioapi.audionodes.OscillatorNode;

    var context:AudioContext = new AudioContext(stage.frameRate);

    var oscillator:OscillatorNode = context.createOscillator();

    oscillator.connect(context.destination);

    oscillator.start();

  

### GainNode

  

* [GainNode](http://webaudio.github.io/web-audio-api/#the-gainnode-interface)

  

The instance of GainNode is created by createGain method.

  

    import audioapi.AudioContext;

    import audioapi.audionodes.OscillatorNode;

    import audioapi.audionodes.GainNode;

    var context:AudioContext = new AudioContext(stage.frameRate);

    var oscillator:OscillatorNode = context.createOscillator();

    var gain:GainNode             = context.createGain();

    oscillator.connect(gain);

    gain.connect(context.destination);

    oscillator.start();

  

### AudioBuffer / AudioBufferSourceNode

  

* [AudioBuffer](http://webaudio.github.io/web-audio-api/#the-audiobuffer-interface)

* [AudioBufferSourceNode](http://webaudio.github.io/web-audio-api/#the-audiobuffersourcenode-interface)

  

The instance of AudioBuffer is created by decodeAudioData method.  

The instance of AudioBufferSourceNode is created by createBufferSource method.

  

    import audioapi.AudioContext;

    import audioapi.AudioBuffer;

    import audioapi.audionodes.AudioBufferSourceNode;

    import flash.events.Event;

    import flash.media.Sound;

    import flash.net.URLRequest;

    var context:AudioContext = new AudioContext(stage.frameRate);

    var sound:Sound = new Sound();

    sound.addEventListener(Event.COMPLETE, function(event:Event):void {

        context.decodeAudioData(sound, function(audioBuffer:AudioBuffer):void {

            var source:AudioBufferSourceNode = context.createBufferSource();

            source.buffer = audioBuffer;

            source.connect(context.destination);

            source.start();

        }, function():void {

        });

    }, false, 0, true);

    sound.load(new URLRequest('sample.mp3'));
