Hey, I have a question about how to make nice, thick, tough car sounds. I have some good recordings of car sounds and was wondering if there are any good techniques to beef them up and make them sound real.
Distortion can be very useful in this regard. Most car recordings are very clean and need to be messed-up a bit to become believable. Experiment with varying degrees of distortion and see what sticks - each car and each situation will be different. Also, as mentioned before, bass enhancers like LoAir and Rbass are great for adding that nice meaty bottom. And when you're all done with those processes, finish it off with some limiting and see where you end up.
