A finished game will have hundreds if not thousands of sounds that all need to make their way to the speakers that the player is listening to. As you’ve learned, sounds in Wwise originate from sources such as audio files or signal generators, but the journey that each signal takes from its point of origin, through the Wwise mixing system and on to your computer’s speakers can vary. Much like in Digital Audio Workstations and conventional mixing consoles, source signals can be combined together onto busses for easy organization and control of the signal flow. Portions of signals can be sent via Auxiliary Sends to apply Effects. In this lesson you’ll explore how to build these pathways and, more importantly, understand why they are necessary.
