Even if you're mixing yourself, it's better to add EQ and compression only when you can hear how it will sit with the soundtrack or special effects. Ultimately, it comes down to knowing what your voice will be used for and making a judgement. For instance, if I'm recording a tagline for a TV or radio advert, I'll generally run a mic into a nice preamp (where I might add slight tube warmth, and subtle EQ or compression, just to give the recording a bit of 'body'), and I may do a little de‑essing using a plug‑in when performing any edits. However, for e‑learning jobs, corporate videos and so on, I'll tend not to add any creative processing while recording or editing, and will only use the de‑esser ever so slightly.
1. You need to get oriented with the industry. You need an education in this business prior to investing in it—especially if you hope to be valuable as a voiceover talent. You need to understand who your core clients would be and who you would eventually create a voiceover demo for, namely, producers. If you’re not servicing them, then you’re not servicing your self. This is precisely why I wrote, “The SOUND ADVICE Encyclopedia of Voiceover & The Business of Being a Working Talent.” You need insight as to what’s needed and wanted of you in this field, and how professional sessions are run, otherwise you’ll likely frustrate yourself with unrealistic expectations.
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.
Once you’ve identified a pool of candidates based on skills and availability, look at their experience and browse their gig gallery. Listen to samples of previous voice-over work to get a sense of their style, and choose the candidate whose style you like best. You can contact them before ordering, explain your project requirements, expectations, and budget, and provide examples of work you like by the seller or someone else as an audio reference.
A better, more natural-sounding way to clean up a voice recording, though, is to paste in strips of 'silence' that showcase your home studio at its best. To do this, wake up early (ie. when your house is quiet), turn on your gear and set your levels for a normal job. Then record a full minute of silence at whatever bit depths and sample rates you're likely to be using. Repeat this process for each different mic you use, and save each file in a folder titled Room Tones, or something similarly suitable.
"Ideally the talent should be seated, staying on axis, approximately a foot away from the mic, which should be angled back from the face a bit, not parallel to it. You'll need to see what angle provides the best results, usually a few degrees off from parallel works great — and located between the forehead and the nose, not directly in line with the mouth. This will help with plosives, mouth noise, and some other issues. Movement in the booth should be limited, as the microphone is likely to pick up arms flailing, hands rubbing, page turns, stomach growling, and so on. Keep the levels consistent, moving closer if the scene calls for a whisper, or moving back for a loud voice or scream. A well‑versed narrator is capable of delivering a dynamic performance without creating dynamic levels.”
