Control the cues
Gunshots and explosions in CS2 can bury the quieter cues that tell you what happens next.
Blast Guard uses selective compression to give you control over the relationship between those loud effects and the subtle information underneath them, so you can hear everything in-game.
- Lower the Loud reduces gunshots and explosions while leaving footsteps and other subtle cues untouched, decreasing brain fatigue over long sessions.
- Footstep Enhancer raises footsteps and subtle cues without changing the intensity of gunshots and explosions - if you never want to miss a sound cue again.
