PHP: MP3 Customization (Voice overlay)

Hello,

I am trying to find a solution for the following problem for ages now:

How is something like that possible:

http://audiojungle.net/item/who-we-are/105018

People can upload their mp3 file and audiojungle automatically overlays them with the trademark "audiojungle" (female voice throught the whole song).

How is something like that possible? Flash? PHP Class? If so, are they open source?

Thanks in advance

 

Why not purchase it too see? $12 ?

 

AJ does postprocessing after the upload finishes. Its not PHP.

 

DAN i hope he is asking for the script like that

 

Hi,

I am not,just wondering how they do it.

You guys know any script which can cut mp3 files? For example the first 30 seconds or something, just like this class: http://www.sourcerally.net/Scripts/20-PHP-MP3-Class

It doesn´t work properly though, not reliable enough for production purposes.

Bye

 

I can only think of 2 ways to manipulate audio files with PHP, one is bit manipulation (like the class you linked to does) and the other is using a command-line tool with exec(), preferably wrapped in a PHP class.

 

I didn´t really get what krsix meant by AJ and postprocessing. Could you explain?

Thanks
