I was thinking about this some more today. What I think would be awesome is like, practice problems. Maybe you create 10 or 20 EQ “problems” that each consist of two short tracks–a kick and a bass, or a guitar and a vocal, or two different synths, etc.–and the student opens up a problem in their DAW and applies an EQ curve to each. Then they compare their finished product with the “answer” which consists of the track that the teacher came up with, and a screenshot of their EQ curves or something.
This isn’t like math where there is only one right answer. However, if they listen to their answer and the teacher’s answer, they may think, “whoa the teacher’s sounds way better, how did they do that?” Or they may think, “I like mine better. Let’s see if I can figure out what is good about the way they did it.” Either way you can learn something useful. Either way it gets you listening and thinking.
I feel like this could even be done SoundGym style, as a web application. That takes any variation in plugins out of the picture. Obviously you couldn’t auto-generate the problems, but you could have “problem packs” designed by all kinds of teachers. But that’s probably a huge project that no one has time for, lol. Maybe I’ll send the idea over to SoundGym. One thing I like about them is that they really do keep coming out with new features. I think they could be onto something cool.
