rss2audiobook is a Perl script that converts your RSS feed into iPod playable audible audiobook format.
It uses Microsoft Speech SDK via Win32::SAPI5 to make wav file from text content, then encodes the wav file into AAC (m4a) using Apple iTunes COM and finally renames .m4a to .m4b so that it can be recognized as an audiobook file by iPod. Pretty nice collaboration of Microsoft and Apple, glued by Perl Win32 magic!
It'll be an interesting hack to make RSS 2.0 enclosure from your RSS feed automaticaly, to enable Podcasting without speaking your Blog entry by yourself ;)
