Messing around with coding a message and sending/receiving it over audio/mic. Doesnt work....yet....

audio-chat.js

var sen = "The quick brown fox";


function codeMessage(message){
	var bin = '';
	var message = sen.split('')
	for(var i=0; i < message.length; i++){
		var letter = message[i];
		var code = letter.charCodeAt().toString(2);
		bin += new Array( 8-code.length+1 ).join( '0' ) + code;
		//bin += bin;
	};
	return bin;
}

function decodeMessage(bin){
	var response = '';
	for (var i = 0; i < bin.length; i += 8){
		response += String.fromCharCode( parseInt( bin.substr( i, 8 ), 2 ) );
	}
	return response;
}




var codedMsg = codeMessage(sen);
var decodeMsg = decodeMessage(codedMsg);
console.log(codedMsg);
console.log(decodeMsg)

var ac = new (window.AudioContext || window.webkitAudioContext);
// C4, E4, G4
var freqs = [400];
var oscs = [];

for(var i=0; i<codedMsg.length;i++) {
  var o = ac.createOscillator();
  var g = ac.createGainNode();

  o.frequency.value = codedMsg[i] === 0 ? 400 : 1000 ;
  console.log(codedMsg[i])
  
  g.gain.value = 0.25;
  g.connect(ac.destination);
  o.connect(g);
  oscs.push(o);
} 

var i=0;

var tone = setInterval(function(){
	console.log('here')
	oscs[i].noteOn(0);
  	oscs[i].noteOff(0.5);
	if (i === oscs.length)
		clearInterval(tone);
	else
		i++;
}, 500)
