You are correct. It broke my heart after an hour into editing...I was hoping it wouldn't be noticed or at least not overly distracting. Must have been a glitch with OBS or my linux audio driver because I haven't been able to reproduce it.
Would you say it's bad enough to warrant a re-record?
I don't think it's bad enough to warrant a re-record. Even with it this tutorial (and entire course) is so, so awesome!
