I have a beeping signal and I am trying to get that translated to 0 and 1. And it works, but then it comes to really fast beeping it can't found out the 0 (no bip).

Here is a sample of the signal ( Lower your volume before testing it!! ): https://www.dropbox.com/s/fqxxirg9y8gc4t2/test_sound.m4a?dl=0

navigator.getUserMedia = navigator.getUserMedia ||
navigator.webkitGetUserMedia ||
navigator.mozGetUserMedia;

if (navigator.getUserMedia) {
    navigator.getUserMedia({
    audio: true
},
function(stream) {
    audioContext = new AudioContext();
    analyser = audioContext.createAnalyser();
    microphone = audioContext.createMediaStreamSource(stream);
    javascriptNode = audioContext.createScriptProcessor(2048, 1, 1);

    analyser.smoothingTimeConstant = 0;
    analyser.fftSize = 256;

    microphone.connect(analyser);
    analyser.connect(javascriptNode);
    javascriptNode.connect(audioContext.destination);

    javascriptNode.onaudioprocess = function() {
        var array = new Uint8Array(analyser.frequencyBinCount);
        analyser.getByteFrequencyData(array);
        var values = 0;

        var length = array.length;
        for (var i = 0; i < length; i++) {
            values += (array[i]);
        }

        onOff = (values / length) > 30 ? 1 : 0;  // <----------- Here
        console.log(onOff); 

    }
},
     function(err) {});
}
