So, as it turns out, my microphone was crackling throughout the recording session. It's sporadic, but it's enough for me. I might have grabbed the wrong headset, since I have 2-3 that have issues and don't work properly as well as a set I bought just for this occasion.
I'm deleting and restarting my playthrough. I can't, as a man of with a modicum of standards, in good faith force anyone to go through that when it's something I can easily remedy.
Sorry to everyone who's already watched the first episode, but it'll be changing and will hopefully be without sound issues when it returns.
