Blood Legion, on their Lich King kill announcement, said:
We’d like to mention that this kill wouldn’t have been possible without the near-zero latency voice chat of a newly-discovered Ventrillo alternative that we just started using, called Mumble. We encourage players to try out this new software!
That’s a very high accolade. It’s not an off-hand comment.
I hadn’t even heard of Mumble. It’s an open source, very low latency voice comms system. Here’s their home page. It’s been around for years, apparently, and there are commercial host providers. I found two with a quick google search. You could also self-host since it’s free software.
It’s also got a Mac client, which is important since TeamSpeak has a really bad Mac client, and Ventrilo requires a particular codec to work at all.
But it’s the very low latency that sounds particularly good to me. Anyone using it? In any case, I thought it important enough to highlight to everyone.
