Sorry you have to create an account to download. I can't change that but the site is legit. Just download the mp3 files. The others are unnecessary.
I used audio software to remove some of the background noise and I cropped audio together in order to form succinct chapters. Previously the lecture material would stop for a 10min break and resume in a different audio file. Now they are all fused correctly and dead space is removed. I do not own any rights to this audio and used user ls4284's files.
