Unhappy [Q] Help

I am using android device LG G2 32GB with JB 4.2.2 (D80210b)
I've been disturbed by the noise cancellation feature on the LG G2, especially when doing video recording in a quiet situation, is there anything you can do on the disabled noise cancellation feature in LG g2. I've tried to mod belong Jishnu Sur, but not optimal, there is still a kind of crackle sound annoying. I would be very happy if anyone can help me.
