Adding audio files and video files

How to use PDF documents with audio and video as multidimensional communications tools
PDF files are the ideal exchange format since they can be opened on any platform and they avoid those notorious conversion problems that can occur on devices with different operating systems. But here's something not many people know: Adding audio and video files is just as easy as including text, images and graphics. This is the kind of feature that can create tremendous value, not only because it eliminates having a bunch of bothersome email attachments, but because it opens the way to what is truly a rich and full-scale multimedia communications experience.
