Как я могу загрузить записанное аудио на Titanium?

Я пытаюсь загрузить записанное аудио, но всегда получаю пустой файл на стороне сервера …

это мой код для аудиозаписи:

    var currentSessionMode = Titanium.Media.audioSessionMode; Titanium.Media.audioSessionMode = Ti.Media.AUDIO_SESSION_MODE_PLAY_AND_RECORD; var recording = Ti.Media.createAudioRecorder();
// default compression is Ti.Media.AUDIO_FORMAT_LINEAR_PCM
// default format is Ti.Media.AUDIO_FILEFORMAT_CAF

// this will give us a wave file with µLaw compression which
// is a generally small size and suitable for telephony recording
// for high end quality, you'll want LINEAR PCM - however, that
// will result in uncompressed audio and will be very large in size
recording.compression = Ti.Media.AUDIO_FORMAT_ULAW;
recording.format = Ti.Media.AUDIO_FILEFORMAT_WAVE;

Ti.Media.addEventListener('recordinginput', function(e) {
Ti.API.info('Input availability changed: '+e.available);
if (!e.available && recording.recording) {
b1.fireEvent('click', {});
}
});

win.addEventListener('close',function(e) {
Titanium.Media.audioSessionMode = currentSessionMode;
});

var file;
var timer;
var sound;var label = Titanium.UI.createLabel({

win.add(label);

function lineTypeToStr()

и это мой php, чтобы получить мои данные и отправить их по электронной почте:

<?php

$mailto = "[email protected]";
$subject = "teste";
$message = "mensagem teste";

print_r( $_FILES );

$file = $_FILES['userfile']['name'];
$file_size = $_FILES['userfile']['size'];
$handle = fopen($file, "r");
$content = fread($handle, $file_size);
fclose($handle);
$content = chunk_split(base64_encode($content));

// a random hash will be necessary to send mixed content
$separator = md5(time());

// carriage return type (we use a PHP end of line constant)
$eol = PHP_EOL;

// main header (multipart mandatory)
$headers = "From: FeedBack Team <[email protected]>" . $eol;
$headers .= "MIME-Version: 1.0" . $eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol . $eol;
$headers .= "Content-Transfer-Encoding: 7bit" . $eol;
$headers .= "This is a MIME encoded message." . $eol . $eol;

// message
$headers .= "--" . $separator . $eol;
$headers .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . $eol;
$headers .= "Content-Transfer-Encoding: 8bit" . $eol . $eol;
$headers .= $message . $eol . $eol;

// attachment
$headers .= "--" . $separator . $eol;
$headers .= "Content-Type: application/octet-stream; name=\"" . $filename . "\"" . $eol;
$headers .= "Content-Transfer-Encoding: base64" . $eol;
$headers .= "Content-Disposition: attachment" . $eol . $eol;
$headers .= $content . $eol . $eol;
$headers .= "--" . $separator . "--";

//SEND Mail

if (mail($mailto, $subject, "", $headers)) {
echo "mail send ... OK"; // or use booleans here
} else {
echo "mail send ... ERROR!";
}

?>

Видно, что я не загружаю правильно мои аудио записи.
Кто-нибудь может помочь мне загрузить записанное аудио?
Я использую Titanium 3.4.0 GA и разрабатываю для iOS и Android
Спасибо
