Get your computer out of the room. Your microphone will pick up fan noise from your computer. Unless you have a solid state drive that is completely silent, you will want to set up a monitor in your studio and run cables through your wall to a computer outside the room. You can use a wireless keyboard and mouse to control your recording software. This also cuts down on the heat of your studio.
You will never have to answer to a “boss”, but you will need to be your own boss and manage yourself. You will work on your own a lot of the time. So you need to embrace the benefits and the challenges this presents. Take courses in areas where you need to develop your skills. When you adequately prepare for running a business, you will succeed in its management, even if part of managing your business means hiring out, in areas that you know are not your strongest.
"This was Alfre Woodard's audiobook directing debut, and she pulled an amazing performance from people. The big [thing] was to remember that these stories were being told in intimate settings, one‑on‑one in most cases, so the talent really needed to speak to the individual listener. An image kept in mind was stories being told around a campfire, back when folktales were passed down by spoken word.”
As editor, you need to turn the raw recording into the final version of the file you'll be sending to your client. Editing during a recording session can be problematic, and particularly so if you're recording in a domestic environment. How can you expect to hear the drone of the dishwasher ruining your recording if the dishwasher is still running as you edit? I'll look in more detail at setting up a voiceover recording studio next time, but for now, if recording in a separate room or isolated booth isn't an option, at least try to edit the file the following morning (or maybe at night) when there's less noise around — because hearing your recording with a fresh ear and in a quieter environment will help you to make better editing decisions, and will reveal noises that slipped your attention earlier.
