There's all kinds of different... "textures" of information. Some things are extremely thick with information. Every few sentences, I might need to pause and think through all the implications and realizations that are revealed to me. In audio form, I'm rewinding or pausing, and consuming at <1x speed. Other sources might spread the important details and facts around. I'm better served by speedreading / skimming / playing back at (>?)2x speed. This strains my short term memory less, letting me assemble the important bits into a broader, deeper understanding of the material, that can contextualize all those snippets in a way that makes it easier to commit to long term memory. This can happen even with information dense material, in which case I'm better served by repeatedly skimming, than trying to do a single solid readthrough once. And then there's the stuff that wasn't even worth skimming through once.
