I need a program that combines .mp3 files, and makes all possible combinations of them. For instance, let's say I have 3 .mp3 files 10 seconds long each ([login to view URL], [login to view URL], [login to view URL]). This program would combine all files into one, in every possible order to create various 30 second long files. So it would create:
[login to view URL]
[login to view URL]
[login to view URL]
[login to view URL]
[login to view URL]
[login to view URL]
This program would need to handle up to 10 input files.
This program can be web-based, or desktop.
