"Still working on it if anyone has a good idea on how to scale the distance please post " I think it's because of the game units halo uses, but if anyone else knows, post please!

What does this do, exactly?
It sounds interesting, but I'm not exactly sure what it does.

3d positional sound..so when you are talking to your teamates while playing...it sounds like their voice is coming from their character. Never used it, but when I get my pc working, I'll finish this plugin for Prolak and test it out.

But Halo doesn't have support for voice.., unless you mean to say this would work if you were using teamspeak, vent, or xfire voice.

Doesn't matter though. It's just like how normal sounds work in game. Say someone is shooting a weapon, you can tell which direction they are because of positional sound the game uses. Mumble takes advantage of that and just applies it to voip. That's what this plugin is for, so it works with halo. And no, it doesn't work for teamspeak or vent, cuz it's for mumble only. Other voip software doesnt have this technology, yet.

This is a Mumble plugin, not a Halo plugin.

Mumble reads Halo to figure out where everyone is and then applies directional sound to them.

I've never heard of mumble. Sounds cool, but I guess everyone uses teamspeak now. Maybe you should switch over to this, lancer ;p

I'm still confused as to what this affects, but don't expect me to understand all this "mumble" jumble. (get it? ha.. :v:)

E: Alright, mumble is a voice chat program, now I [sorta] get it.

Maybe I will, at least until TeamSpeak 3 is released.
