Audio mp3 merge script similar to oldspicevoicemail.com

Audio mp3 merge script similar to [login to view URL] First check [login to view URL] I need a script like that but more basic It has to merge/mix 1. intro mp3 2. the given digits in the input box ( only digits an maybe a max of 30 ) 3. outro mp3 Example intro mp3 file + 0114866994 mp3 files + outro mp3 file interface only a input box and generate button VERY IMPORTANT !!! If you click on generate there must come a share to Facebook message. After the post on the wall ( not profile ) the download starts automatically. If there is no share = no download The script must run in Joomla, maybe a component? If it can be done in Joomla +++ Or a total individual script easy to implement in a Joomla page. Need some support ;-) The script will be used for different audio mixes, but always the same basics ( intro+digits+outro ) The files have always the same name total 12 files [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] > > > [login to view URL] [login to view URL] Placed in a map, for an other mix i can only change the map somewhere in the script???
