(You need this software)
Step 1: Open your sound file and add "Change Pitch" effect to it like in the picture + the right values.
Step 2: Add a second Effect (Bass and Treble) and change the values like in the example below.
(The first step is more essential as you can see, the second one just adds a bit more bass to it)
And that's it, you can save your file now.
NOTE: These are just my settings that I used to make the original game files sound similar to the filtered ones you hear while you're playing the game. Feel free to adjust any values you want or add extra effects to it to sound even more legit.
