Tech blurb go!
Before I start, I'd like to say that I am not a professional, and all the stuff I've written here comes from advice from people who work in the music and/or voice over industries, and from my own noob experimentation. Don't take what I say as the gospel truth, but rather as a starting point for your own learning and experimentation. I'm writing this with amateur or hobby voice acting in mind, although some of the tips I write can apply to the professional world as well.
I said I was going to cover these points:
1) Equipment and how to set it up
2) Proper mic techniques
3) Audacity and Reaper overview
4) Some useful effects/settings/plug-ins
I started typing them all up, but it ended up being super long, and my CTS is killing me. So I'll focus on just one of the points in each post. Today's post is about:
Equipment and how to set it up
Here are the basic things you need to get started with voice acting:
Microphone
Pop shield/pop filter
recording software
At the amateur or hobby levels, the brand and type of microphone is not as important. Let me repeat that:
the mic is not as important! An expensive mic is not necessarily a guarantee of good sound--the setup is much more important. I've had quality problems with my expensive Zoom H2 recorder because I didn't set it up correctly. Of course having a good mic will help a lot, but I've had decent results recording with a headset that I bought at the dollar store--yes, a $1 headset! Of course, since it was that cheap, it fell apart after about two weeks of use (cheap wiring, boo), but I digress... The point is, don't worry too much about the mic, and don't spend a lot on it if you don't have the budget for it.
As for equipment recommendations...google. There are many people more knowledgeable than I who have written articles about it, so just do a search for "best mic for [your budget]" and pick one you can afford. Or just use your webcam mic, headset mic, or whatever you have on hand.
What's important is that any mic you use, at whatever price point, should have a clear enough signal. That is, you should be able to adjust the volume levels so that you can hear your voice loud and clear with little to no static or other mic noise. If your mic is super bad, do upgrade to a better one. If you can hear your voice fine, even if there is a little bit of static, there are methods to fix that with post-processing, which I'll discuss later. However, you really do want to get it as clear as possible so that you avoid any difficulties later.
Ideally, you should record in a small, quiet space with no echoing. People have recorded in closets, cars, small rooms...the possibilities are endless. This isn't always possible to do, however, and that's ok. The important part is that you should really minimize any background noise. Shut your dog up. Turn off all the fans/ac/whatever. Close your windows and doors. To minimize echo and to absorb noise, you can hang quilts on the walls.
Another possibility to think about if you don't have a good acoustic space is to build a mini-recording booth just around your mic, like
this one. They're pretty easy and cheap to make. The best results come from acoustic foam (expensive!), but for our purposes other cheap alternatives can work well enough, like inexpensive foam, layers of old rags sewn into squares, or a cut up quilt. Or you can even build a pillow fort around the mic...looks stupid, but it can work pretty well, apparently. I've never tried the pillow fort method myself, but some swear by it. Whatever you do, it is important to isolate the mic as much as possible from any outside noise.
When you plug your mic into the computer, whether it's a usb mic or one you plug into the mic port, you want to adjust the gain/volume levels in your recording program so that it is loud as possible without static/mic noise and clipping. Clipping is when you speak as loud as you will go into the mic and it pops into the red zone of your recording program. It'll produce a horrid crackling sound when that happens (not to mention it's bad for mixing), so adjust the levels down in that case. Generally, don't go beyond +/-3dB.
If you're using a headset, don't worry too much about this part. This is mostly for table-top or other mounted mics. Set your mic up on a stable surface as far away from your computer as possible, so it doesn't pick up any fan noise. Ideally it should be about level with your mouth, but depending on your mic's "sweet spot" you may want to move it a bit higher or lower or a bit left or right. It's different for every mic, so experiment with the placement to get the spot that works best with your mic and your voice.
A pop shield isn't strictly necessary, but it can really help filter out the plosive consonants and some other unwanted noises. You can buy them if you want, but you can also make them cheaply out of old pantyhose and a wire hanger. Basically, bend the hanger into a roughly circular shape big enough to cover your mic, then stretch the pantyhose over it. You can bend the hook of the hanger into a stand, or twist it to wrap around the base of the mic or some other place. If you're using a pop shield, set the shield up about 3in from the mic and place yourself anywhere between 1-7in away from the shield.
As for recording software, use anything you are comfortable with. I use Audacity and Reaper, which I will discuss later.
Those are pretty much the basics for equipment! Next post will be about proper mic technique.
