This program is meant to visualize the directional left and right sounds heard in many video games. I first thought of this when one side of my headphones broke and I had a lot of trouble playing some of my favorite first-person video games. The scope of the problem goes beyond broken headphones; people with impaired hearing are put at a disadvantage, especially in games where directional sound cues are critical. My aim is to solve that with a visual indicator of stereo sounds.
Plus, I can't hear anyone to the left of me in Valorant.
You should be able to just run the .exe and an overlay will show up. You may have to play your game in fullscreen windowed if it isn't showing up.
Sorry for the lack of documentation. I wrote most of this at 3 AM and my brain just wasn't there :)
