OOC, what are you listening to? The youtube playlist has 2 videos for each lecture, a zoom recording focusing on the slides with the professor visible on camera, and a classroom recording - the latter definitely has better audio quality, but the audio quality of both is far better than your average OCW lecture from 10 years ago.
It's ironic that the audio quality of most AI online courses is terrible.I'm looking forward to the moment when AI can be used to improve the audio of these lectures, especially older ones like the Feynman lectures.[1]
