No doubt, the headline above applies to many businesses, but since I'm in the voice over world, I'll touch a bit on what I know. As a politician has said more than a time or two, "Let me be brief."
"El Cheapo" voice overs are aplenty. With the explosion of affordable, digital audio equipment, many are hanging up the "I'm a professional voice over talent" shingle. Problem is, when it comes time to deliver the goods, they fall short. And not just in their abilities, but in the actual sound quality of the audio.
Getting good, clean audio in a home studio set up is not quite as easy as it may seem. For one, each recording space has a unique room tone. That is to say, XYZ microphone will sound differently if it's used in this room versus that one. Some record from voice over booths. Others create an isolated space with proper acoustical treatment. I use products from this company. Then there's the additional challenge of blocking outside noise if you're recording in a busy neighborhood. When I moved into my new studio location several years ago, my main goal was to find a very quiet location, so buffering outside noise would be minimal. I was very fortunate to find a cool spot that literally sits near a quiet creek. Love it!
If you're planning on hiring a voice talent and having them record a paragraph or two of your script as an audition, listen to the audio with headphones on. This will highlight any audio deficiencies that may not be audible through your speakers. Things like computer fan noise, excessive echo flutter bouncing off walls, or let's hope not, but even barking dogs in the background, will be readily noticeable.
I'll wrap this post up by saying that I have made more than a few dollars from producers who have phoned me in a mild panic because they hired a low priced talent and needed a quick fix on a voice over.
