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.
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.
Because I've prepared properly, the first take is often the one I end up editing and sending to my client. The second is simply there as a safety net, in case I need to replace any mistakes while editing. It's much better to capture such drop‑ins during the same session as the main performance, as you can be sure that the mic will be in the same place and your voice will have a similar character in both takes.
One of the most important rules is to ensure you value yourself as a professional. If you undervalue your own service it can be hard to later charge for the correct rates. A professional voice-over should cost a minimum amount, even if you’re new. If you allow clients to low-ball your work from the outset it will continue to set the expectation that they can get a voiceover from you on the cheap. This can then mean the difference between making a living and paying bills or not.
When asked by someone outside of the industry how much I’m compensated for a commercial voice-over, I can see their eyes grow large with excitement. It may sound like a large number for two or three hours of studio time, but what is not understood is the investment in time, money and education that it takes to begin and sustain a voice acting career. As voice-over professionals, we need to remember (especially if we are setting our own rates) that the time we have spent in classes, coaching sessions, and our booth add up to our expertise in this field. When setting your own voice-over rates, or negotiating those set by producers and/or clients, you need to not only consider your session fee (the time spent in the booth recording the specific copy), but also all the training you’ve acquired and the investment in your home studio (which helps make your client’s job much easier).
