javascript make beep sound

  var oscillator = context.createOscillator();
  oscillator.type = "sine";
  oscillator.frequency.value = 800;
  oscillator.connect(context.destination);
  oscillator.start(); 
  // Beep for 500 milliseconds
  setTimeout(function () {
      oscillator.stop();
  }, 500);
}

beep();

// See source for a parametrized sound

//if you have another AudioContext class use that one, as some browsers have a limit

//duration of the tone in milliseconds. Default is 500
//frequency of the tone in hertz. default is 440
//volume of the tone. Default is 1, off is 0.
//type of tone. Possible values are sine, square, sawtooth, triangle, and custom. Default is sine.
//callback to use on end of tone
