This is really helpful, but I have a comment about the aesthetics. The blue text on the light marbled background is really difficult to read. I'm sure not everyone has a problem with it, but I get migraines and tend to be sensitive to stuff like that. But thanks for putting in all the work; i especially like that you've put in nuanced and descriptive terms, like "sparse" and "turgid."
Oops. I sort of forgot about this thread. Thanks for the suggestions. I've added QAM, SSE, SDE, and RBE to the glossary. I also changed the text color to black. You're right Kathy, the blue text can be a bit hard on the eyes.
I was thinking about adding something on reference level, but can't seem to locate Maskeeper's tutorial.
Maybe put the terms for different types of speakers in there. ie reference, bookshelf, etc. Some of them are self-explanatory, but it's nice to know for certain what they're meant to be used for and where.
