If you are going to be a successful broadcaster, you need to have a broadcast quality studio, or else your files will be returned to you and your reputation will plummet. Buy the best microphone you can afford, but it should be the right one for your voice. You need to go to a well-stocked music or audio store in a city, test out some of their price range, and record your voice using a high-end “pop” filter ring on each … essential for all broadcasters. Request playback through decent HiFi speakers in a quiet room. Don’t just listen through headphones live, that won’t give you any useful feedback on the quality of the microphones you’re testing.
So what are you listening to on playback? Well, an announcer needs a microphone that picks up all the “nice” harmonics in his voice and lessens the “bad” elements. I personally use a Neumann U87 and Neumann TLM 103, as they seem to suit my deep bass voice. It gives my voice resonance and authority while maintaining the clarity of the top end (treble). Years ago when testing microphones, I found that Electovoice microphones made my voice muffled for some reason, and AKG’s were thin and lifeless when recording my voice. However, I know voice actors who love these other microphones, so you have to see what is right for your own voice and the way you use the microphone.
You will find USB mics at really good prices (like the Rode NT or the Audio Technica AT2020) but I suggest you avoid them. A professional speaker really needs a traditional large condenser microphone with an XLR audio jack, not a digital USB jack. As a general rule of thumb, you’d be looking to spend at least $ 500 on a microphone, and you may be lucky enough to find a neat, used one on the net for a big discount on the new price. At the microphone shop, I would also buy a good quality pop filter (dual filters are usually the best) and a quality balance angle type mic stand so you can position the mic exactly correctly, plus a cage or stand Microphone spring does not pick up desktop vibrations.
So how does the entire voice actor connect? The mic needs to be plugged in with a thick quality shielded XLR cable into a very good quality preamp such as a Focusrite Scarlett or Steinberg UR 22 (which I have) which is then plugged into a USB port on a computer. Aim for total silence in both the microphone and the recording chain and also in the room or voice booth in which you are recording. Unless you simply want to record hard-selling “screaming” scripts, there will be times when the slightest bit of interference or hum will ruin what is called the “background noise” of an actor’s voice-over recording. Once you have found a quiet room, the walls and ceiling should be treated with acoustic foam tiles. This should be done to create a “dead” recording area without acoustic reflections.
You may not want to record your audio on your computer. I really don’t. I’d rather connect my mic to a standalone solid-state recorder, my trusty old Marantz PMD 661. It gives me more flexibility to pull out the SD card for audio editing on train rides, and I like the confidence that the recorder is alone. doing your job 100% of the time and without any computer program interfering.
So what about where you go to record as a voice actor? At home, you’d ideally have a large room or even a garage with a built-in professional voice booth, but they are very expensive, at least $ 4,000. These cabs are very heavy and come in a huge box in kit form. They are basically a big box that you enter through a door and there is usually a window. Inside there will be a desk and chair, in addition to your screen microphone, keyboard, and mouse.
If you can’t afford or have the space for a voice booth, you would probably start with a small room that you would adapt. Remember you want the obnoxious, noisy computer with its fans OUTSIDE of the room you’re in, next door with appropriate USB cables and amplifiers leading to your keyboard, mouse, and screen in front of your configured microphone. Or if you have a soundproof closet that offers ventilation for the computer, that might work too. The audio output cables should also go to your amplifier and speakers and audio meters (ideally sensitive professional PPM meters) in your studio which will have a headphone jack for sessions led by phone or Skype, or any of the systems like ipDTL that They are very high quality “record to end” setups.
On the computer, you will need audio editing software, (I use Adobe Audition) Skype, Word, PDF reader and that’s it, plus the email system you will use to receive papers. It won’t cost a fortune to set up a good home studio, but a fortune is what you could earn as a successful broadcaster. Good luck for you!
