Hello, Imagine we have cars in a scene. As the cars go far away, their sound will change. Here is a video that shows how it changes in real life: As you may notice from 00:49 to 01:05, there are some frequency changes. I'd like to do the same to the car sounds of my project. But I don't have any clue how to mimic this. Would be glad if someone could shed some light and help. Regards.
