I have tumbled across this new codec recently. Not exactly sure how new this is, but until now it has eluded me, which I am surprised as I do a weekly check for new songs for my MP3 player. After a lot of fiddling by using a special guide, I managed to get this codec supported by my Windows Media Player, but was not there by default. It sounds like this is a superior quality that separates it from all others. How true is this? Because no portable device seems to support this yet!
