I´m looking for a script that can do the following:
A customer visits my joomla-website and combines different audio-files (wav or mp3) via a order-form that will be automatically combined/rendered into a new single audio-file. Then the customer can download the resulting file against payment via paypal and other pay-systems.
Example: File 1= Hello.mp3, File 2= world.mp3; resulting file = Hello world.mp3
The second version would in addition make it possible to combine the files also by letting them sound at the same time.
Example: File 1= Hello.mp3, File 2= world.mp3, File 3= background-music; resulting file = Hello world.mp3 with background-music
