I think if I was to do another university course, I'd just point a camera at the prof/white board for whatever they're talking about/writing, and then write down a much smaller set of things I'm interpreting for what they're talking about.
Quickly retyping/rewriting what they're saying never got me any benefit, though that was mech eng courses where nothing the lecturer says matters at all compared to practicing the math.
I've had success in a lecture situation by printing the slides beforehand with huge ass margins and then taking notes on said margins while the prof was talking.
That does require the lecture to have slides that are given to the students before the lecture though...
