New .amr File Format Accepted
I added support for the .amr audio file format. It is a highly compressed audio file format that is used on mobile phones. Like the 3gpp mobile video format I added before, it's default player is quicktime 6.3. However, I believe other programs can play and/or support this. Maybe @uncutsaniflush can figure something out if they don't. If not just make sure you have quicktime support, it is free at 

As you know there is no quicktime for linux. And firefox, bless its pointy wee head, doesn't have a working mime plugine editor at the moment.
If you are interested, i could give you a suggestion of how you could help people who are using operating systems such as linux or *bsd with no official quicktime releases experience the embedded video and audio - include the url of the actual file so that an external streaming player could be used and/or the file could be d/led and viewed offline. I know it's not very elegant. But it would be way better than an empty space. At least peeps that aren't using windows or osX would have a chance to listen and view the files.
