Despite not ever figuring out the original audio issues, I have cobbled together a new mic setup that does the trick!
I will be rerecording and reuploading the last two stories of season three, "Honest End" and "A Sensible Choice," slowly over time, so the audio issues don't have a lasting impact.
Thanks for all of your patience and support as we make our way into the final season of the show!
