Try uploading the file as form data

audioRecorder.exportWAV(function(blob) {

      var url = (window.URL || window.webkitURL).createObjectURL(blob);
      console.log(url);

      var filename = <?php echo $filename;?>;
      var data = new FormData();
      data.append('file', blob);

      $.ajax({
        url :  "lib/vocal_render.php",
        type: 'POST',
        data: data,
        contentType: false,
        processData: false,
        success: function(data) {
          alert("boa!");
        },    
        error: function() {
          alert("not so boa!");
        }
      });
}); 

.

<?php 

if(isset($_FILES['file']) and !$_FILES['file']['error']){
    $fname = "11" . ".wav";

    move_uploaded_file($_FILES['file']['tmp_name'], "../ext/wav/testes/" . $fname);
}
?>

According to the documentation, by using XMLHttpRequest.send() you can use the Blob object directly.

var blob = new Blob(chunks, { 'type' : 'audio/webm' });
var xhr = new XMLHttpRequest();
xhr.open('POST', '/speech', true);
xhr.onload = function(e) {
  console.log('Sent');
};
xhr.send(blob);

I've tried this and it works like a charm.
