So I am currently making an audio visualiser and I want it so that when a specific frequency hits the object will be black. Currently, whenever a specific frequency hits it is white. This means I have to invert the f curves. Is there a way to do this?
An alternative to inverting the curve is inverting how the curve affects the material. The curve will remain the same but the resulting colors will be inverted.
Create a value node and create a keyframe for it. Bake the sound curve to it.
After that you can invert the values with an invert node.
