To USB or Not To USB
One of the most exciting advances in audio technology is the USB microphone. These devices approach the concept of the "Digital Microphone" that has been spoken of by audio prophets for decades. Basically it's a good old-fashioned analog mic with backend analog-to-digital electronics that creates a digital data stream from the mic signal. This data is then sent to your computer over a USB cable into your computer's USB port. COOL!
The PROS
The upside of USB mics is that you need no extra hardware to use them. Plug your USB Mic into your Laptop and you're good to go!
The CONS
So what's the downside? Well, bunches. First of all, some USB mics don't allow to to adjust the GAIN or amplification of the mic. If it is adjustable it might be switchable in different levels. Second, all of that processing and digitizing and transmitting causes a lag in the signal we call "latency". This latency makes it difficult to monitor your voice in real time by listening with headphones. There is a distinct "lag" in the headphones that give you that "Elvis in the Stairwell" effect... very disconcerting. Finally mixing the mic signal to, say, split it to route it to a phone patch is nigh unto impossible.
The FIX
The manufactures are aware of these shortcomings and a few have added features to overcome them. The Samson G Track, the Rode Podcaster and the MXL.009 have adjustable analog headphone jacks for zero latency monitoring. The Samson G Track and MXL.009 also has gain adjustment on the mic. Also the MXL Mic Mate Pro lets you turn an ordinary mic into a USB mic with headphone monitoring and gain control.
Look for other manufacturers to add these features to their newest offerings.

level one: getting started--quality audio for the lowest investment
RECORDING SOFTWARE
Lets talk about the recording software first.
If you have a PC (or a MAC including Intel Macs or Linux) you can download and install recording software called Audacity. Audacity is a open source program that’s a FREE download that will let you record, playback and export your recordings as well. It has some peculiarities but it produces broadcast quality audio and allows for very easy editing to clean up your auditions or do final production for a client.
The download is here:
http://audacity.sourceforge.net/download/
You also need to download the LAME library to create mp3 files. Start on this web page:
http://audacity.sourceforge.net/help/faq?s=install&item=lame-mp3
And here's some good documentation to explain how to use Audacity. There's the Audacity User's Manual and the Quick Reference Guide:
http://audacity.sourceforge.net/help/documentation
If you have a recent MAC you’re in luck. Newer Macs come with the Garage Band application installed. Garage Band is recording software for the Mac that allows you to record, play back and export you recordings in all the popular file formats.
Both of Audacity and Garage Band produce broadcast quality audio so with either one your good to go.
USB MICROPHONES
So now you have your recording software. Next you need a quality microphone. If you're trying to keep the cost down the most most convenient mics that I've found are USB Microphones. These mics don't require any type of interface box--they simply plug directly in to your computer's USB port. The mic takes your sound and then digitizes it right in the mic and sends it over a USB cable to your computer to be recorded. You can get a good quality USB mic for $100-$250. I prefer a better condenser mic because they have a wider frequency range and are less noisy than dynamic mics.
The upside of USB mics is that you don't need additional hardware so with your laptop and mic you're up and running.
The downside is that there can be a slight delay in the signal (called latency by us audio freaks) so if you want to listen to yourself with headphones as you record you get a slight "Elvis in the stairwell" delay. This is more pronounced with software monitoring as opposed to hardware monitoring.
A SELECTION USB MICROPHONES
There are many new USB mics coming along all the time. Here's are the good quality ones I'm aware of at this point.

If you already have a quality microphone (a low impedance condenser for example -- not a headset or a rock 'n' roller's SM58, or a Guitar Hero mic) here's handy gadget from MXL that let's you convert it to a USB Mic. |
MXL Mic Mate |
 |
This is the new fancier version of the Mic Mate that allows you to monitor the mic with headphones with zero latency AND adjust the gain of the mic--all things considered, I would get this one. |

OTHER ESSENTIALS

You'll also need a microphone desk stand or regular mic stand. Usually I like to stand up for performances so I use a boom stand but for long sessions or practicing I'll get lazy and sit down and then I use a desk stand. |

And a pop filter to tame those nasty "P" and "B" sounds |
You might also want to get headphones to listen to your playback. Headphones let you hear every detail, noise, room echo, etc. Good ones to get are Sony MDR 7506. They're pretty much an industry standard. |

So where do you get this stuff? Well, not at Best Buy. These types of products are available at most big music stores such as Guitar Center and Sam Ash and the like.
You can also shop online at Musicians Friend, Sam Ash, Sweetwater, and other online stores.
*** URGENT URGENT URGENT ***
DO NOT PAY "RETAIL" FOR ANYTHING!! ALL THIS STUFF IS DISCOUNTED TO SOME DEGREE!
IT MIGHT HAVE A "LIST" PRICE OF $250 AND ACTUALLY SELL IN THE STORE FOR $99!!
CHECK OUT THE PRICES ONLINE AND PRINT THEM OUT TO ARM YOURSELF
WITH THE FAIR PRICE WHEN YOU ACTUALLY GO TO THE STORE!!
*** THAT IS ALL ***
Gasp! So there you have it. The bare bones you need to produce broadcast quality audio and perform voice overs from home. Obviously I can't assist each one of you in setting up and learning the equipment and software but each of the manufactures has documentation that can help. But here's the basic scheme:
If you really get stuck please contact my installer pictured here:
two hints for recording
The LEVEL of the USB MICROPHONE is adjusted in the computer:
CONTROL PANEL >> SOUND (PCs) or
SYSTEM PREFERENCES >>SOUND >> INPUT (MACs).
Some mics let you ADJUST THE LEVEL ON THE MIC
Adjusting the level is like Goldilocks and the three bears: Not too hot, not too cold. Here's a pic that shows good recording levels:

Always record your voice to a MONO TRACK (NOT STEREO)!! You've only got one mouth (I hope!) and one mic so you only need ONE Track. A stereo track wastes hard disc space and can have weird audio problems (phase shifting, artifacts, echoes) when mixed to mono.
finally..
The only way to learn to record is to do it. You can read a book about how to use a hammer but sooner or later you've got to go out and pound some nails. So set it up, test it out, debug it and have at it. There's an entire world of happy ears out there waiting to hear your golden pipes!
Good Luck and Have Fun!
Coming soon: a more advanced system including preamps, compressors, interface boxes, phone patch, ISDN and more!
