Voice Chat

In Review - feature maturity not classified, documentation in progress and likely to change

Overview

Spatial Audio provides large-scale, spatialised voice chat between players. You will often hear it referred to by its historical name, “Crowd Audio”, and some files still use this name. The new name, “Spatial Audio,” is meant to convey the support for all kinds of audio, not just crowds of people talking!

The spatial audio system consists of three parts:

• The spatial audio Unreal plugin. This integrates the system with Unreal and provides an API to game code.

• The audio client. This is a DLL that provides engine-agnostic processing functionality, and provides an interface to the connection between the client and the audio server.

• The audio server. The server receives audio from each client, performs processing and aggregation, and then sends the mixed audio back to each client.
