I built these free compression tools because most producers learn compression from YouTube videos and blog posts, but never get hands-on practice with how settings actually work. The calculator gives you real-world starting points based on what you’re compressing and what you want to achieve. The visualiser shows you what attack and release are actually doing to your signal in real time. Both are free, no sign-up required.
