Back in 2003 Skype released their Super Wideband Audio codec which was supposed to be a lot better than all other audio codecs. (better sound less bandwidth.) And they give it away with a royalty free license. So Logitech started making headsets to support it, and Valve added it to the steam friends voice chat and TF2 voice chat.
I can't find it listed as a feature on headsets or sound cards from other brands. Do they support it? Aren't audio codecs just software? Do I really need to buy a specific headset to make use of this codec? and if so, why aren't more manufacturers supporting this codec?
