Trebor, I see you use even more bands than I do and a higher top frequency. You must be very patient! My work has everything above 11.5 kHz stripped out by other parties so I don’t worry about that.
You probably know this: if you choose Spectrogram view, then the bands you specify do not correspond to equal divisions in screen height. But choose spectrogram log F instead – then they do correspond to equal heights. And that’s how a graphic equalizer’s sliders work too.
