The Audio Source Controller is designed to simplify and amplify your game audio. The Audio Source Controller adds some common functionality for your sound effects, such as varied pitch or sequenced audio clips, and puts it all into the inspector. The only programming required is a single function call.
Additionally, the Audio Source Controller comes with an Audio Manager that offers game-wide volume control when paired with the Audio Source Controller.
Finally, the Audio Source Controller is designed to be modular so it's very easy to add your own audio effects!
