Mumble (software) - Positional Audio

Positional Audio

For certain games, Mumble modifies the audio to position other players' voices according to their relative position in the game. This not only includes giving a sense of direction, but also of distance.

To realise this, Mumble sends each player's in-game position to players in the same game with every audio packet. Mumble can gather the information needed to do this in two ways: it either reads the needed information directly out of the memory of the game or the games provide it themselves via the so-called link plugin interface.

The link plugin provides games with a way to expose the information needed for positional audio themselves by including a small piece of source code provided by the Mumble project. As of 2012 this interface was mostly used by open source games.
