Removing particular sound from Insurgency Sandstorm

Hello, guys

I am just an average gamer, but I am trying to fix my experience because developer has not addressed it. Every time someone speak in voice chat, I hear an annoying beep, and it’s just spammed all over, it’s really painful.

Can someone explain to me (I don’t code anything, but willing to try the tools to do so) how to remove the beep from the game.

Any explanation is appreciated, maybe I will learn some stuff too :slight_smile:

Example:

It’s much sharper in actual game before video encodes to Youtube
