I need a plugin which will allow to watermark mp3 files before download started:
- visitor come to the website, and gonna to download my music
- he must - enter his e-mail, then his e-mail recording as watermark in mp3 files
- mp3 files zipped and his download link ready
For what, user uploaded files in the internet, I’m dowloading those files, opening and see his e-mail in mp3 files data, so I know who did it.
