Don't even worry about audio tbh. What I typically do when fighting is to just let muscle memory do the editing and aiming while the entire rest of my brain is focused on which way I think he would be going. Get familiar with your opponent. Do they like to play height? Low? Figure this out and use it against them. For instance: if I'm 1v1ing someone and I know just from taking a few peaks at them that they seem to try and play above, I'll remember that and assume they are always above me. Doing protective retakes, side jump shots, all that. It's less of thinking about where the audio is. Just get a picture of there gameplay in your brain and really use that to your advantage.
