According to (local docs): file:///E:/Program%20Files%20(x86)/Unity3/Editor/Data/Documentation/Documentation/Components/class-AudioLowPassFilter.html
There is supposed to be some curve editor GUI for setting the rolloff curve that controls the low-pass frequency based on distance from audio source.
However, I've looked everywhere I think, and I don't see such an interface with such a curve, even though I add the Audio Low Pass Filter component. Do I need to add some sort of new curve component, or is the documentation just erratic?
I really like this feature as it makes for realistic sound effects in large environments, so I'd love to get it running.
