The videos are actually available in 1080p. If you can re-do the audio and tell me how I can do that in YouTube without re-uploading the video (it's embedded, for example, in the university's Moodle), I will gladly do that. If not, as I said, I'll do proper recordings once I got more time. I did up to 4x 2.5 hour videos a day last week to get the lectures up on time. You can actually hear that in my voice sometimes. I absolutely agree with your approach to learning.
