$mp3config['encrypt_name'] = TRUE not encoding?

[eluser]stevenazari[/eluser]
this is a live site so how can I do it without being obtrusive to the members, I don't see this error so when I upload everything goes through fine. - I would need to send an email to myself right?

if I put a list of tmp files into an array, then do the !is_file statement, I can email myself what should be expected with the bandtrackupload variable and compare it to the tmp folder list? but is the file moved before or after the codeigniter upload configuration setup?

Code:

//Should I create tmp_folder array here?
$mp3config['upload_path'] = './media/audio/';
$mp3config['allowed_types'] = 'mp3|MP3';
$mp3config['max_size'] = '0';
$mp3config['encrypt_name'] = TRUE;
$mp3config['remove_spaces'] = TRUE;
$this->upload->initialize($mp3config);

//Or should I do it by here?

$this->upload->do_upload('bandtrackfile');
$bandtrackupload = $this->upload->data();
$date = time();

//Or should I do it by here??
                
// Do S3 audio/mpeg
if (!is_file($bandtrackupload['full_path']))
//and then send myself an email here...?
//I like turtles.
