Mumble is a free voice chat communication, geared toward gamers. The program is lightweight, and runs in the background without interrupting your gameplay. Mumble is best known for low latency and impressive sound quality. Players can take advantage of additional plug-ins that integrate the program with the game, for example, we can disable the microphone for w while.
Mumble acts as a server-client, so in order to connect with other players we must first connect to one of the many available servers and create a channel that easily accommodate a large number of players. However, if we are not able to create your own server, there is nothing to prevent the log on one of the public (free) servers and create your own channel where you can chat with friends.
Probably, the most interesting thing about Mumble is that it grants the possibility to make the players' voice come from the direction their character is actually placed. In addition to this, the program has a graphical overlay that is displayed in the corner of the screen, even when we're playing.
Overall, Mumble definitely deserves to give it at least a try and can be recommended those who need a convenient way of chatting while in-game. The excellent sound quality and functionality combined together, make the app a good choice.
