SEND CHILLS UP YOUR MICROPHONE WITH AN ICICLE
One of the really great computer applications is the ability to
record audio and save it to a digital file. One of the more
interesting recording applications these days are podcasts. Making a
podcast is fairly straightforward. Besides the computer, all you
basically need is the recording software and a microphone. As far as
the recording software is concerned, deciding what program to use
can be somewhat daunting in that there are so many titles available
from which to choose. Usually the choice gets narrowed down to a few
titles and that's based upon the number of features you want and the
price. There are free ones all the way up to versions costing
hundreds of dollars. And pretty much like their counterparts, you
get what you pay for it. Please understand that I'm not saying the
free or low cost recording products aren't worthwhile because many
of them are. You're just going to have to make the effort and try
them out to see if the program will do what you want.
What I'd like to focus on here is the microphone you'll be using to
make the podcast. The microphone you choose can literally make or
break the podcast. No one really wants to listen to what you have to
say if it sounds like you're talking from a bathroom. That's the
sound of the reverberating echo we all love to hear when we're
singing in the shower. Technically it's called "reverb" and singers
love to use it. But when it comes to the spoken word, it's something
to be avoided unless your intention is to sound like something dark
and spooky on a Halloween night.
When it comes to computer microphones that are designed to plug
directly into an available USB port, typically these are general
all-purpose omni-directional mics that will pick up anything that¹s
close by. So when you use one of these microphones to record an
interview for example, you're pretty much guaranteed you will get
your voice, the interviewee, the sounds of you talking that are
bouncing off the walls and floor (if there's no carpeting), any
white noise generated by air movement and sundry other background
sounds you may not have noticed before you made the recording. What
you need is a unidirectional or cardioid mic. These
professional-grade microphones are designed to only capture the
sounds that are made within inches of the mic's pickup area. They
typically use an industry-standard balanced, XLR connection.
Balanced mics make excellent recordings because they have no line
"hum." Unfortunately these mics typically aren't made to directly
interface with a computer's USB port. Fortunately I've discovered a
relatively new device that will let you connect any XLR mic to a USB
port.
The Icicle from Blue Microphones is a small 4 inch tube with
connections on each end. It's both a USB converter and mic preamp
that renders the proper physical and electronic connection and makes
the connection pretty much hassle-free. I tested out an Icicle with
my AKG cardioid studio microphone that I have been using on my
Computer America radio show. I tried using it on both a Windows PC
and a Macintosh. It couldn't have been more easy. Without any
additional software, I literally plugged one end of the Icicle into
an available USB port using the included cable and plugged the mic
into the Icicle's other end. On the Mac, I simply selected the Blue
Icicle selection that appeared in the Sound Preference panel's input
tab. I launched the recording software and spoke into the mic. The
audio quality was simply glorious. The vocal recording had a
presence unlike anything I've ever made using a computer microphone.
Given the excellence of the cardiod mic I was using, it all made
perfect sense. Using a common mic made for a computer doesn't stand
a chance next to a professional-quality model.
The Icicle has a few other nice little touches such as a 48V phantom
power source that supports condenser mics that require power to
operate. The Icicle also includes a gain control knob that lets you
further refine the volume level and a power active light that makes
the Icicle product lettering glow blue. It's a nice touch. If you
want to make one of the best possible recording qualities on your
PC, then this may be a really good way to go. The Icicle sells for
$59.99 and is available at the Blue Microphones website.
