The filetype you are attempting to upload is not allowed.

Code Shown below:

    $config['upload_path'] = getwdir() . 'voices/';
    $config['allowed_types'] = 'wav|mp3';
    $config['max_size'] = 2800000;
    $config['file_name'] = rand();
    $this->upload->initialize($config);
    var_dump($config);
    if ($this->upload->do_upload('file')) {
        var_dump('uploaded');
    }else{
        var_dump($this->upload->display_errors());
    }

var_dump($_FILES['file']);

  array (size=1)
 'file' => 
    array (size=5)
      'name' => string 'blob' (length=4)
      'type' => string 'audio/wav' (length=9)
