A few weeks after our conversation, Apple released version 10.8 of Logic Pro, its flagship digital audio workstation (DAW) and the big sibling to GarageBand. Stuffed inside the update was Mastering Assistant, Apple’s own take on AI-powered mastering. If you were a Logic user, you suddenly got this capability for free—and you could run it right inside your laptop, desktop, or iPad.

Keep in mind, they’re not talking about mixing, but mastering, which are two very different things. I’ve tried a service that did this a few years ago, and, it did really well, even back then. If you’re not semi-knowledgable about this space, it might scare you, but there have been hardware versions of this sort of thing for decades. It’s more science than art. There’s just no amount of listening on various speakers and in different rooms that can dial in whole-mix EQ so that it sounds right on everything these days. The process is, in fact, very mathematical, and can be automated. In short, “nothing to see here; move along.” This is just the next logical step.
