Ah, in the audiobook (and most voice act/over) community, it’s actually more or less a given to post edit your own recordings. I mean, you can outsource that or sometimes the company would have their own audio engineer(s), but that is very rare. If you deal with indie publishers/game companies, for example, they would want ready-to-use recording. Personally, I would want to learn it myself too because I can be particular on how I want to sound like, haha. 😂
