Upon receiving the data, remote instances of the app must submit the data to their own instance of Game Chat 2 via chat_manager::process_incoming_data. The app must deliver the data contained in the game_chat_state_change object to the remote instances of Game Chat 2 specified in the same object. Once configured, Game Chat 2 polls audio from the local users' microphone(s), performs automatic gain control and voice activity detection, encodes the data, then exposes the audio data to be delivered to remote instances of Game Chat 2 via chat_manager::start/finish_processing_data_frames. The app then configures the relationships between each user. The app informs the library of users on the local device and users on remote devices that are expected to chat together.
