In other words, Mirek gave us all the information we needed to start the job. Unfortunately, though, that's not how it usually works! Usually, you'll need to work hard to get all the information you need from your client to do the job well. If you're at all uncertain about their expectations, whether about the performance, or about technical and organisational issues such as file formats or payment procedures, save yourself time and a headache by clearing up all doubts beforehand, and don't hit the record button until your client has given you the green light by email. With that sorted, you can more easily don your other hats and get on with the job.
Why the difference in approach? Lots of my e‑learning and corporate jobs are done for production houses that will be adding other voices to the mix. Ironically, if I record my voice via a great mic and preamp, and add some nice processing, it can end up standing out from the other voices, drawing attention to itself. The production house will see this as me causing them a problem, even though my recording sounds better than the others! 

"We recorded two or three takes of each story, and within those takes there were some pick‑ups [overdubs] for certain lines. When I was editing, I used takes that gave the best delivery, had the least movement or other noise, and provided the most provoking images. In some cases [we used] the first take. Sometimes, after saying a line over and over, one starts to lose the meaning of the line. Pick‑ups should go back to the top of the sentence, making editing much easier.”
First of all let’s dismiss the obvious – there is no such thing as a standard rate, there are only guide lines and even these vary by Country and type of work. The only standard rates are those set by some Union scale rates. One of the most notable differences is that between voice over union rates and voice over rates non-union. Unions provide a standard voiceover rate and therefore you can safely rely on the unions guide (depending on which Country you are in). However, non union voice over rates vary enormously and are often down to negotiations between the voice over actor and the client. 

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.
