Be mindful of the sounds of your heating and cooling system (this goes for a home recording studio, as well). If you can’t find a spot where you can’t hear air rushing through your ducts, you may want to shut down your furnace or AC for the duration of your recording. If your recording space is near a window, listen for sounds of traffic — especially loud trucks. They will definitely show up in your recording.
As I've mentioned, most of our clients prefer to do post‑production work themselves, and request the raw (but edited) recordings. Sometimes, though, as in the Avast! job, the client will want the files ready to go, which might mean using slight EQ and compression. The noise floor on my recordings generally hovers around ‑54dB, but by using EQ to roll off frequencies below 80Hz and above 12kHz, I am usually able to lower the noise floor to around ‑57dB without resorting to noise reduction. Using EQ to reduce low‑end rumble and high‑frequency noise will make your recording sound better, and will be particularly beneficial if you'll be adding compression later, as the compressor's make-up gain won't be raising the level of that noise. Used moderately, compression can usefully reduce dynamic range, and thus improve intelligibility of the words, while still leaving you with a natural‑sounding result. Used excessively, it will suck the life out of a recording.
Some of you might be wondering about the difference between voice over and narration. The short answer: not much. In most cases, you may use voice over and narration fairly interchangeably. However, to be technically correct, narration typically refers to an audio vocal that describes all the action on screen or tells a story based on what’s happening, while voice over may or may not describe as much action and is often more instructional in nature.
"We recorded two or three takes of each story, and within those takes there were some pick‑ups [overdubs] for certain lines. When I was editing, I used takes that gave the best delivery, had the least movement or other noise, and provided the most provoking images. In some cases [we used] the first take. Sometimes, after saying a line over and over, one starts to lose the meaning of the line. Pick‑ups should go back to the top of the sentence, making editing much easier.”
Congratulations! You should now have a finished voiceover recording. Save a final copy with the extension _master and use this version to save another copy in the format requested by the client. But don't think your job is done when you hand everything back to your producer‑self. Running a profitable home‑based voiceover business takes more than building and equipping a home studio and recording and editing audio files. You still have to design a web site, launch a marketing campaign, and secure new clients — all of which is something we'll look at another time.
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.
