Some clients are not experienced in voice over. So another way you can help them is to advice then and help them really understand all that goes into a voice over recording to get it to the final polished result. Of course you need to take this into account when you charge for your time and again whether this is a one off project or has potential to be a long term client.
As the engineer, your key job is to select and set up the recording space, choose and position the microphone, set levels and make sure you're recording a good, clean signal at a healthy level. Like music, the louder the signal you want to record, the less audible the noise floor, but you don't want to have to speak louder than sounds natural, and you don't want to overcook things when tracking: any distortion will be very noticeable on an exposed voice part, and an otherwise great take with digital clipping won't be acceptable. If you notice clipping only when you start editing, software clip restoration tools might help to make the take usable, but it's not going to be perfect. Remember that although you may have needed to record 'hot' on analogue tape and older 16‑bit digital recording systems, modern 24‑bit A‑D converters can accommodate a much wider dynamic range, so you no longer have to track so loud: you can leave much more headroom.
Like pacing, vocal tone and inflection refer to ensuring you speak in a natural and pleasant manner. You want to be friendly and engaging, but not so much that you sound fake. No one wants to sound like a game show host. But, you also want to avoid monotone robot voice which, like pacing that’s too slow, can be boring and off-putting for listeners.
The clarity of your voice and a comfortable volume may be the most essential parts of great audio. If your voice over recording is fuzzy or muddy sounding, it will be difficult for people to understand. Audiences likely will be distracted and unable to absorb the information or may simply move on. Either way, they miss your message and you miss an opportunity to share what your knowledge.
I use the Adobe Audition package to edit my own voiceover work, but the techniques described below can be used in most audio‑editing software. Start by saving a new version of your original recording. (I keep the name of the file the same, but change the extension from _original to _edit.) Next, I'll turn my attention to the end of the recording, where I stepped away from the mic after the second take and recorded about 10 seconds of silence. Although processing is usually kept to a minimum, dealing with sibilance is important, and Eiosis' De‑esser plug‑in is much more precise than most.Wearing headphones, I can zoom in on this 'silence', turn up the volume, and listen for any background noise. If I notice any constant noise seeping into the recording, I may consider using Adobe Audition's noise‑reduction tool to capture a one‑ or two‑second profile of the silence, and then reduce the offending noise by about 75 percent throughout the recording. I should stress that this is rarely needed, and it's always a last resort, because such processing can generate swirly, metallic artifacts that draw more attention to themselves than the noise you intended to eliminate! But it's good to listen for such issues with fresh ears at the start of your editing session. If you find yourself using noise‑reduction often, that's a sign that you should find a better place to record, or improve the isolation of the space you've chosen. Don't forget that there are other ways to deal with some noise: often, a high‑pass filter is all you will need to clean up a recording, for example. Also remember that if your recording is to be mixed with music, slight background noise won't be noticeable, and that the more exposed your voice in the end product, the more problematic noise will become.
Our recommendation is to start small and reinvest the money you make into upgrading your equipment and set up. All clients, whether they are Pixar or just a guy who needs a voicemail message, expect crystal clear audio recordings. You absolutely MUST be recording in a professional recording environment with professional equipment. They are NOT going to settle for less than perfection. Does this mean spending thousands of dollars? Maybe, eventually it does, but not today. What you’ll need to get started:
In late 2009, my wife Simone received an email from Prague in the Czech Republic. The sender, Mirek Jirku, was heading up a project to record voice messages for the foreign‑language versions of the latest Avast! anti‑virus software. Mirek sent us eight messages to be recorded, specified the fee and deadline, and requested a slow, friendly read. He asked us to send separate stereo MP3 files (at 160kbps or higher quality) for each message, specified that we'd have to sign a non‑disclosure agreement before recording, that we'd need to invoice afterwards, and that he'd pay via a wire transfer instead of PayPal (which is often used for international payments).
"When recording voiceovers at home, you have to focus on performance: keep your energy levels up, stay true to the page, pronounce words correctly and consistently, and make sure you keep to a schedule to make the deadline. Prep well so you don't waste time second‑guessing yourself, looking up words as you go, and remember to not over‑ or under‑direct yourself. Also, make sure you know your recording equipment and room well; being able to quickly make adjustments to mic placement, levels, and so on, will make you more efficient.”
