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.

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).
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.

While having a broad set of voice skills is beneficial, many voice overs establish themselves in commercials and more general corporate voiceover work before specialising. Having a niche or specialist focus though can make a difference in earning potential. So, bearing in mind the question: how much money do a voice actors make, will also depend on the level and experience in a given niche e.g. animation, audiobooks or gaming.
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.

Recording voice overs like a pro isn’t that difficult when you know how to do it. You may have noticed that the actual recording part plays little part when compared to the preparation. Taking the proper steps before you hit the record button and then taking the time to edit your audio appropriately will go a long way to ensuring your voice overs sound professional and engaging.
I’m new to this so keep that in mind, but I use a cheap “dog training clicker” to mark my redo portions. They are very visible in the sound track. In longer recording sessions (where I won’t remember the error) I’m experimenting with using 1,2 or 3 clicks to indicate how far I plan to back up for the restart. I can often find and do the cut without have to play anything – that by having an idea of how far back I need to look.
"This was Alfre Woodard's audiobook directing debut, and she pulled an amazing performance from people. The big [thing] was to remember that these stories were being told in intimate settings, one‑on‑one in most cases, so the talent really needed to speak to the individual listener. An image kept in mind was stories being told around a campfire, back when folktales were passed down by spoken word.”
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.
If a client likes your demo, they may invite you to audition. In the 21st century, you can download the audition script, record the audition at home, and then send the results to your client over the Internet. Prepare yourself for a life of constant auditions: Even successful voice pros may do many more auditions than actual jobs. But if enough jobs come your way, it's worth 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.
Important: Use headphones to check the audio quality of your test recording. Your computer speakers will not be good enough for this. Headphones allow you to listen closely to ensure clear audio. Obviously, you want the audio to sound good on even the cheapest speaker, but you will be much happier if you use headphones. Remember, a good portion of your video viewers will listen this way, so you want to be sure they’ll have an optimal experience.
Another factor to consider is how the project is being used and in which medium. If you record a commercial that’s airing nationally on television, then that is a larger rate than a regional television commercial specific to a certain market. The voice-over spot you worked on is being seen by more viewers nationally as opposed to regionally, which warrants more compensation. You should not only consider your session fee, but also get the specifics on how the voice-over is being used. My personal opinion is to avoid “in perpetuity” usage because as your career develops, something which was not a conflict in the past could be in the future. If the spot you had conflicts with another brand in which you are auditioning, this could become a conflict that was unforeseen when you initially booked and recorded the job.

A demo recording of you doing voice-over work is your CV and your business card combined. If you're applying for a voice-over job, you can send the potential customer your demo via the Internet. Ideally you have multiple demos for different types of gigs. For commercials, clients want to hear 60 to 90 seconds of voice work. If you're auditioning as an audiobook reader, five minutes of demo proves that you can stay in character over a longer stretch of time.
