My biggest fear about narrating my own audiobook was the editing. The lore says three or four hours of surgery per finished hour.
So I described the wall to the model instead of climbing it. It built an editor that transcribes the session, finds every place I said "redo," works out where the botched take started, cuts it, and queues anything uncertain for my review.
How else would I get that? Buy it from someone?
