Not all noise can be tackled in this way, though: you need to listen for clicks, plosives, digital glitches and the like. These can normally be acceptably repaired by using a 'heal' tool, or a pencil tool to redraw the waveform. Popped 'p's can often be 'fixed' using a high‑pass filter set at 100Hz. For a single glitch, you can zoom in and cut out the cycle of the waveform in which the glitch appears. Just be careful to start and end the cut where the waveform crosses the centre line, otherwise you'll inadvertently add another digital glitch. If glitches are frequent, it's likely that there's a problem with your audio interface's buffer settings — it may be just a playback issue.
Some might think that the audio portion of a video takes a backseat to the visual portions, but that’s not true. Most video watchers note that they are more likely to stop watching a video with bad audio vs. lower-quality video. In fact, a recent TechSmith study of video viewing habits showed that more than 25% of video viewers watched a video all the way through because the audio was good — more than those who said professional video style was most important.
When you come to actually recording your voice, try to think of the mic as the ear of your listener. Picture your listener, have an opinion, and read the script as if the words were coming to mind that instant. The distance between your mouth and the mic should be about the same as the distance between your thumb and pinkie when making a hang‑five gesture (see the picture above). Move closer to the mic when you lower your voice and back off when you speak louder. On‑line dictionaries such as the Merriam‑Webster one pictured here, often include audio examples which can help you clarify pronunciation. Just make sure that you use an American English or UK English (or other language!) version as appropriate. (Remember, while you have your engineer hat on, to take account of this when setting levels.) Always use a pop shield, and I'd suggest trying to work slightly off‑axis, as talking to a point just to the right or left of the mic will prevent bursts of air and drops of saliva ruining your recording. I'd also recommend wearing headphones over one ear only, as this allows you to judge volume and listen for clipping and plosives on the recording, while also hearing your natural voice, which makes it easier to focus on that message we talked about. Simone demonstrates this technique in the picture on the next page. Hhe's working slightly off‑axis and has backed off an inch or two to deliver with more energy.Typically, you'd record with your mouth approximately the distance between your thumb and little finger from the mic, as pictured here.
Important: Use headphones to check the audio quality of your test recording. Your computer speakers will not be good enough for this. Headphones allow you to listen closely to ensure clear audio. Obviously, you want the audio to sound good on even the cheapest speaker, but you will be much happier if you use headphones. Remember, a good portion of your video viewers will listen this way, so you want to be sure they’ll have an optimal experience.
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.
We screen our talents to make sure your voice recording has a professional broadcast quality level. Once you order a project, your money is absolutely safe with us. We do not pay the voiceover artist until the project is successfully done and approved by you. You can asks for revisions at no extra cost as long as they don't involve changes in the script.
At this point — unless you're tracking for broadcast applications (where they don't work to peak levels) — consider 'normalising' your recording to an optimal level. Normalisation can be used to push the loudest peak to around ‑1dB and increase the volume of the entire recording by the same ratio. Of course, you can also tighten up dynamic range (the difference between the softest and loudest parts of your recording) by manually reducing the loudest sections of the recording before you apply normalisation. On a final note, if you do plan to use a compressor, then you might as well add gain at that stage instead of normalising.
