Streaming mic over sockets using IO socket and Node JS

I am making an application where I want the user to use their microphone (on their phone) and be able to talk to each other in the game lobby. However, this proved to be more than difficult.

I am using Node JS socket io and socket io stream

on my client i am using audio api to input microphones (it doesn't bother me that much because i am going to make this Native IOS app)

    navigator.getUserMedia = ( navigator.getUserMedia ||
                     navigator.webkitGetUserMedia ||
                     navigator.mozGetUserMedia ||
                     navigator.msGetUserMedia);

    if (navigator.getUserMedia) {
          navigator.getUserMedia (
            // constraints
          {
            video: false,
            audio: true
          },


    function(localMediaStream) {
        var video = document.querySelector('audio');
        video.src = window.URL.createObjectURL(localMediaStream);
       lcm = localMediaStream;
       var audioContext = window.AudioContext;
       var context = new audioContext();
       var audioInput = context.createMediaStreamSource(localMediaStream);
       var bufferSize = 2048;
      // create a javascript node
      var recorder = context.createScriptProcessor(bufferSize, 1, 1);
      // specify the processing function
      recorder.onaudioprocess = recorderProcess;
      // connect stream to our recorder
      audioInput.connect(recorder);
      // connect our recorder to the previous destination
      recorder.connect(context.destination);
      },

  // errorCallback
  function(err) {
     console.log("The following error occured: " + err);
     $("video").remove();
     alert("@#");
          }
        );
            } else {
                 console.log("getUserMedia not supported");
            }

        function recorderProcess(e) {
            var left = e.inputBuffer.getChannelData(0);
            window.stream.write(convertFloat32ToInt16(left));
           //var f = $("#aud").attr("src");
           var src = window.URL.createObjectURL(lcm);
            ss(socket).emit('file', src, {size: src.size});
           ss.createBlobReadStream(src).pipe(window.stream);
          //ss.createReadStream(f).pipe(widnow.stream);

            }
         function convertFloat32ToInt16(buffer)
       {
            l = buffer.length;
            buf = new Int16Array(l);
            while (l--) {
               buf[l] = Math.min(1, buffer[l])*0x7FFF;
              }      
           return buf.buffer;
         }



             });

         ss(socket).on('back', function(stream, data) {

                //console.log(stream);

                var video = document.querySelector('audio');
              video.src = window.URL.createObjectURL(stream);
              console.log("getting mic data");
            });

      

        
        
        
      

    

i, which I can hear successfully when I speak on the microphone. I am using a stream socket to create a blob to upload to my server ...

        index.ss(socket).on('file', function(stream, data) {
                console.log("getting stream");
               var filename = index.path.basename(data.name);
             //var myfs = index.fs.createWriteStream(filename);

            var fileWriter = new index.wav.FileWriter('demo.wav', {
                channels: 1,
                sampleRate: 48000,
                bitDepth: 16
             });
          var streams = index.ss.createStream();
          streams.pipe(fileWriter);

        index.ss(socket).emit('back', fileWriter, {size: fileWriter.size});


        });

      

        
        
        
      

    

I can't get the stream to write to a file or even a temporary buffer and then send back to the client so I can play or stream the audio in real time. After a while, the server will work, saying that the channel is not available for recording.

Has anyone else encountered this?
