Hi! The "Dare To Compare" page at http://www.xiph.org/vorbis/listen.html is pretty outdated. It is missing modern codecs like AAC+ and WMA9. It also features MP3Enc31, which not even google can identify any more ;-) The page also has "[an error occurred while processing this directive]" at the top and bottom. Regards, David PS: Maybe some links on the page to newer test would do, if there is no time rework it.
