What Compression Does, and Why We Have It Today I’m breaking down the simple, fundamental reason compression was invented—before we even get to the parameters. This is a visual demonstration of how we use compression to control dynamic range. It’s such a basic concept, but it often gets overlooked when you’re trying to learn compression online. If you’ve ever struggled to wrap your head around it, this is a good place to start. I’ll follow this up with videos on how each parameter works—but firs
