Next, run these files through any standard EQ high‑pass and low‑pass filters you use, zoom in on the waveform, and select a one‑second strip of silence from each recording. Save these strips as separate files. For instance, on my system, a one‑second strip of silence recorded at 16‑bit, 44.1kHz on a Neumann TLM103 would have this name: room_tone_neumann_tlm_103_44100_16_one_second.wav. Ideally, the noise floor of each strip will be lower than ‑60dB. Now, when you have to remove a bump or a squeak between words, you can paste in a piece of these strips instead of muting, which would draw attention to the edit.
Part of great voice over work is ensuring that you pronounce each word correctly and that you speak clearly enough to be understood. Avoid mumbling but don’t shout or over-enunciate, either. Don’t worry, though. No one expects you to sound like a professional voice actor. The best thing you can do is speak naturally and clearly and the rest will follow in time.
Before you get down to the nitty-gritty, though, I recommend doing a test recording to ensure your equipment works properly and your audio levels are strong. You don’t need to record the entire script, but a few paragraphs will give you enough to ensure that the audio is clear, at an appropriate level, and doesn’t include any stray or ambient noises.
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.
You need to appreciate that there is a lot to learn and do before your first paid voice acting job. Yes, you want to get out there and start auditioning. But first, you’re going to need proper training, equipment, resources, and yes, some natural talent. The great news is that even though the voice over industry is competitive, there is plenty of voice over work out there for everyone. This guide on how to become a voice actor will give you a good idea of where to start.
Always update yourself on industry standard rates. I recommend reviewing the union rates set forth by SAG-AFTRA. Voices.com also offers a rate card as well Voice-Over Resource Guide. Upon viewing these rates you may find, based on your current experience, you fall a little lower or higher than said rates. Maybe you have a great deal of experience in the commercial voice-over world, but now you’re branching out into narration, e-learning or audiobooks, so your voice-over rates may be a bit lower for that genre as you find your footing. The most important thing is that you have a baseline rate for yourself and you’re comfortable and confident stating this rate to a client. It’s beneficial to first ask your client’s budget and proceed from there. While stating your rate, also take into consideration edits and pick-ups. It’s customary to include one free round of edits in your rate, but any edits or pick-ups past that incur a fee.
