Following a suggestion by one of the members, I added the ability to embed audio files in the page. This works using the website "Clyp.it", which allows to upload audio files without an account.
I don't know if this is the best service for this or if it's lousy, in all honesty I was in a hurry and stopped at the first result in google. Of course I'm open to suggestions if you have different services in mind.
The use is easy, just embed the url to the clip between the tag "clyp" from the "embed" menu.
