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.
Finally, as you complete more work, you can end up with a lot of different files from your projects, so good 'housekeeping' of your sessions and recordings is a must. Glancing at the filename simone_kliass_avast_virus_database_neumann_tlm_103_original.wav, I can easily tell that this is the original recording of my wife's "Your virus database has been updated” message in Portuguese for Avast! on a Neumann TLM103 mic. It doesn't matter what your system is, as long as it works and you can stick to it.
"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.”
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.
A great performance recorded on mediocre gear will always sound better than a mediocre performance recorded on great gear. By preparing well, before the session, you'll find it far easier to relax and focus on the message and the listener. As a producer, it's important to be clear what the expected format is for the final audio file. Although there are certain 'standards', your clients' expectations will vary.Read through the script, look up any questionable words and check their pronunciation. For American English, which accounts for the majority of my work, my favourite pronunciation resource is the Merriam‑Webster on‑line dictionary (www.m‑w.com), which includes audio examples. If you don't know how to pronounce the name of a company or product, call the company's customer service centre (if anyone can pronounce it right, they can!). If you don't know how to pronounce the name of a person or city, try searching YouTube for news reports on the subject.
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.
"The editing process for all our titles starts with receiving the Pro Tools sessions or WAV files and the engineer's script, which has the markings of how many takes there were, and which ones the director liked best. In some cases, I use Strip Silence and add a bed of room tone to expedite the assembly edit. In others I'll add the room tone as I move through the audio. Once I had all the final takes to be used in [Favorite African Folk Tales], I went back to do a fine‑edit pass and created notes on any issues, such as misreads, mispronunciations, noises, and so on. With that list, I was able to discuss with Alfre how we would address the issues. Since the actors' schedules did not permit them to come back in to do pick‑ups I had to do some creative editing.”
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.
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.
