Well, I have an assignment for my audio class. I have to pick a bunch of instruments and decide how I'm going to do the shelving, peaking, boosting and cutting frequencies. What should I write on this thing-a-ma-jig? Should I raise the dB around 2000 Hz? 3000 Hz? Over 9,000 Hz? That's actually still within range of human hearing, supposedly... unless you're old and fat and have tinnitus. But is that where the melodicas live? I'm supposed to find where they live, and boost the dB around there so I can give them happy lives and they can sing clearly, without sounding muffled or tinny.
