This video shows you that with Mumble you have nearly real-time voice transmission, not like TS2 or Ventrilo, which need at least 1 sec. Mumble is a very high quality VOIP-Tool with awesome sound quality, build-in noise and echo reduction (Speex codec at its best) and ultra low latency. Also in lots of games there is a 3D positional audio feature, to see it in game just watch the PR video response. More games are added build for build. ;) So get it! mumble.sourceforge.net
