How to Use

Using the cylon-audio module is pretty easy, pretty much just install the npm module and you are good to go, use it as you would any other device passing along the audio you wish to reproduce. To play audio, pass a full or relative path to the play function. See the example below for further details.

var Cylon = require('cylon');

Cylon.robot({
  connections: {
    audio: { adaptor: 'audio' }
  },

  devices: {
    audio: { driver: 'audio' }
  },

  work: function(my) {
    my.audio.on("complete", function(){
      console.log("Done playing this nice sound.");
    });

    // You can pass a string with a full or relative path here,
    my.audio.play('./audio_samples/audio-sample.mp3');
  }
}).start();
