A free mod for Witcher 3, by Cthulhu aka robx99.
This tool is a very useful utility that allows you to modify the in-game sound to your personal liking. It is a simple and easy-to-use application that allows you to modify the audio files directly on the spot, so you don't need to do any additional work.
The application is based on the open source sound library, which allows you to use the tools that are available in the application to modify the game's sounds. The only thing you need to do is to download the mod, open it, and start using it.
