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.
How much do voice actors make? There is of course no simple answer to this. What you get paid as a voice actor will depend on the type of work, size of project, your experience and many other factors. Some voice actors who are also movie stars, are worth millions. Others, who use freelancing sites can make as little as $30 for a simple radio commercial in a small market. Most professional voice actors fall in between.
Keep it respectable and charge what your time and services are worth. That means establishing some minimums. For example, you might set a minimum price of $100 per job. So if the client says they can get it done locally for less than half that price, you explain that they are getting a professional recording and the difference is in the quality of the recording.
As editor, you need to turn the raw recording into the final version of the file you'll be sending to your client. Editing during a recording session can be problematic, and particularly so if you're recording in a domestic environment. How can you expect to hear the drone of the dishwasher ruining your recording if the dishwasher is still running as you edit? I'll look in more detail at setting up a voiceover recording studio next time, but for now, if recording in a separate room or isolated booth isn't an option, at least try to edit the file the following morning (or maybe at night) when there's less noise around — because hearing your recording with a fresh ear and in a quieter environment will help you to make better editing decisions, and will reveal noises that slipped your attention earlier.
