ownmixing is the process of taking an audio source and rendering it as a number of speaker outputs. If you’re familiar with the way that downmixing occurs in games, you might notice that it is analogous to the microphone array described in the previous diagram.
Typically, an audio source is played in each speaker, and the loudness is directly proportional to how close the source is to where that speaker would be in the game world relative to the other speakers.
