App to control mic input during video recording? (Rooted)

Hey guys so I was wondering if there's any app that can control how much gain the mic gets during videos. I go to concerts a lot and what I really missed about the stock ROM was its dynamic gain, but in AOSP that can become an issue. Does anyone know of any apps or mods that can rememdy this issue? I'm rooted on 6.0.1. Thanks for the help.
