Recording
with an External Microphone
The CC
Witness features a high-quality line-in jack that also
functions as a external microphone
jack. Simply plug a microphone into the line-in
jack, set your CC Witness to "Mic-in" and start
recording! This feature is perfect for
recording live music, interviews, lectures,
recitals, etc., making the CC Witness a great
tool for students, journalists, musicians, and
audiophiles.
When using the CC Witness to record
live audio, the first step toward a quality recording is
choosing the right microphone. Determining which
microphone is "right" depends on the situation. For help
choosing the right mic for your situation, check out the
Cortland.edu page
about basic digital sound recording. But just as a suggestion, for general
purpose recording, we recommend using a dynamic
microphone. |

Once you've chosen which mic
to use, you'll need to acquire the necessary
cables and/or adapters so that you can plug the mic into
your Witness. The best cord for doing this is a XLR to
1/8" stereo cable. This cable has a connection for
a microphone (XLR) on one end, and a 1/8" stereo plug on
the other end. Really, you could use almost any mic cable,
as long as you have a 1/8" adapter on the end that
plugs into the Witness, however, this type of set up
is not recommended as using adapters puts unnecessary
stress on the Witness' input
jack. |

Next, set your Witness to "Mic
(Mono)" or "Mic (Stereo)", depending on which type of
mic you're using. To set your Witness to "Mic", navigate
to the "Settings" option on the main menu. Then go
to "Record Settings", and click on the "Mic/Line
Choice", then choose accordingly.
(If you try to record using an
external mic, with the Witness set to "Line", your
recording will end up very quiet.) |
|
Once you have your CC Witness set to
Mic, and have an external mic plugged into it, you can
start recording. However, for best results, you'll need
to give special consideration to mic placement. The
behavior of sound waves is complicated enough to begin
with. When things like walls, obstructions, and other
noises are introduced, sound waves start to bend,
bounce, blend, and do a number of other things that make
creating a clean recording very difficult. Because of
this, the physical location of the microphone relative
to the incoming sound waves makes an enormous difference
in the quality of the recording. |

INTERVIEW In an
interview-type situation, things are pretty simple. Just
make sure you keep the microphone about six inches away
from the mouth of the person speaking. Holding the mic
too close results in what is called the "proximity
effect". This is where the recorded voice sounds
bass-heavy and punchy. If you want your recording
to sound professional, avoid this as much as
possible.

LECTURE/PRESENTATION/RECITAL When
recording lectures, speeches, and other presentations,
it may not always be possible to get close enough to the
sound source (the person speaking, or the loudspeakers
they are being amplified through). In these situations,
try to place yourself in a central location equal
distance from the main loudspeakers. If possible, hold
your microphone above other audience members, but make
sure it's still aimed toward the audio source. Once you
start recording, remember to limit your movements. Don't
handle and or move the microphone any more than
necessary. Small changes can make great differences in
an audio recording. The single best tip is one of the
simplest. Experiment! Try testing a location
during the introduction of a speech, then listen back
and make any adjustments needed. Every location will
result in a slightly different recording, so trial and
error is sometimes your only choice.

MUSICAL
INSTRUMENTS Recording
musical instruments with the CC Witness is simple, but
making a quality recording with a single microphone can
be a challenge. Please visit the Basic Digital Audio
Recording page for help choosing the best type of
microphone for the instrument you want to
record.
For most (handheld) instruments,
you can get great recordings by facing the mic toward
the instrument but a little off center. The distance
will depend on the room, mic, instrument etc. If the
room has poor acoustic qualities, try recording from
closer.(Don't get too close or you'll end up with a
two-dimensional sound.) In a room with good acoustics,
you can move back a bit. Don't move too far though, or
you'll hear too much of the room. The goal is to find a
good balance. Personal preference will be the ultimate
deciding factor. A stereo mic is ideal to get the most
realistic recordings. If you will be recording louder
instruments, you may need an in-line signal attenuator
to prevent distortion. A simple in-line
volume control
will work fine. This is a common device you can
find at most places where headphones are sold. Don't
think that just moving the mic further away from the
instrument will fix the problem, as doing so will only
lessen the quality of your recording. |

LIVE MUSIC Live music
recording (A.K.A. bootlegging) is one of the most
popular uses for portable digital audio recorders. As an
MP3 recorder, the CC Witness lends itself to this
purpose naturally. In fact, the CC Witness is the
favorite audio recorder of many "bootleggers". The
most important tip to remember if you plan on
bootlegging (recording) live music is to get
permission! Ask the performers before recording
anything. Most musicians won't have any
problem with it, especially if you offer to give them a
copy. If you are a musician, you'll find that the CC
Witness is the perfect tool for bootlegging your
performances, as well as an indispensable tool for
practice. The CC Witness can also be used to
easily record song ideas
or demos.
A well placed mic is crucial for a
solid recording. Ideally, you'll want to position
yourself equal distance between the loudspeakers, and
about as far in front of them as they are apart from
each other. (see diagram) If you can't get to that
spot, try to get as close to it as possible. Avoid
getting too close to the stage though. The view from the
front row is great, but the sound is not. Some people
swear by recording from the sides of the room (close to
the speakers), but every room is different, so you'll
have to experiment for yourself. Pay extra attention to
your surroundings. Any noises around you may end up on
your recording. If possible, keep the microphone above
the heads of the audience members. You may need to move
away from people who are singing along, talking with
friends, etc.
To avoid distortion when recording
loud music, you'll need an in-line attenuator to keep
the signal from overdriving the Witness. An in-line
volume control will do the trick. If you plan on
recording the whole show, just hit record at the
beginning, and don't hit stop until the end of the
encore. You can cut the recording into multiple tracks
afterward. This can be done while playing back the
recording on your Witness. Just press pause where you
want to cut it, then hit "Edit". Select "Divide File",
and then choose "Divide at pause".
To get the highest quality
recording of a live show, your best bet will be to get a
direct feed from the soundboard. Talk to the person
doing sound for the show to see if they can plug the
Witness into the soundboard's out jack (or
headphone jack if the output is being used). You'll have
to supply the cord, so you'll probably want to bring an
1/8" patch cable (or a 1/8" to 1/4" patch cable), or
possibly a RCA to 1/8" adapter cable. Don't bother the
sound person too much though. And don't expect them to
help much either. Most won't mind telling you where to
plug into, but that's about all. If you go this route,
set your Witness to "Line-in (Stereo)" (under the
"Mic/Line Choice" option in the "Record Settings" folder
of the "Settings" menu).

There are some nice
attenuators available (like the one above, by
Shure), but an in-line volume control will work
perfectly fine. (below)
