Effects Example
Copyright (c), Firelight Technologies Pty, Ltd 2004-2016.
This example shows how to apply some of the built in software effects to sounds.
This example filters the global mix. All software sounds played here would be filtered in the
same way.
To filter per channel, and not have other channels affected, simply replace FMOD_System_AddDSP with
FMOD_Channel_AddDSP.
Note in this example you don't have to add and remove units each time, you could simply add them
all at the start then use FMOD_DSP_SetActive to toggle them on and off.
