TITLE: Are there any advanced level math audiobooks?
QUESTION [12 upvotes]: I am aware of a few interesting math podcasts but haven’t come across any interesting advanced math audiobook. Are there some?

REPLY [3 votes]: The Great Courses has a selection of video courses that include graduate level mathematics, for example this course on Discrete Mathematics or this one on differential equations, or one on number theory. These are audio+video, but you might still be able to get useful information out if you only listen to the audio.
