AlterSoundParameter was writted by Anton This needs some kind of collider that triggers the functions "OnTrigger, OnTriggerEnter, OnTriggerExit" What AlterSoundParameter does is altering sounds through FMOD_Parameters, when something with a rigidbody passes through the collider. What things that get altered depends on the variables that the editor enters This script was specifically made as a tool for designers Think of fmod_parameters as parameters that alters for example the "speed", the "pitch" and so on. what they alters and what their names are is specified in FMOD studio by sound and music guys and gals
