2. Microphones
Microphone (mike or mic): A device that
converts sound waves into electrical
modulations for recording.
3. Sound Converting Systems
There are three major types of sound-converting
systems which are used to
classify microphones.
Dynamic
Condenser
Ribbon
4. Dynamic Microphones
These are the most rugged.
They can be used close to the sound
source and still withstand high sound
levels without damage to the
microphone or sound distortion.
They can also withstand fairly extreme
temperatures so they are an ideal
outdoor microphone.
5. Condenser Microphones
Much more sensitive to physical shock,
temperature change, and distortion
than dynamic microphones.
Usually produce higher quality sound
when used at greater distances from
sound source.
Can be used outdoors under certain
circumstances.
6. Ribbon Microphones
Similar in sensitivity and quality to the
condenser microphones.
Produce a warmer sound, frequently
preferred by singers.
Strictly for indoor use.
7. Pickup Pattern
A pickup pattern is the directions (in
three dimensions) in which a
microphone is most sensitive to sounds.
8. Omnidirectional
Omnidirectional microphones have a
pickup pattern in which the microphone
can pick up sounds equally well from all
directions.
9. Unidirectional
Unidirectional microphones have a
pickup pattern in which the microphone
can pick up sounds better from the
front than from the sides or back.

15. Lavaliere
The most frequently used on-camera
microphone in TV.
Can be fastened to clothing with a small
clip.
Omnidirectional or unidirectional with a
dynamic or condenser sound-generating
element.
Designed for voice pickup.
16. Hand Microphones
Microphones that are handheld by the
performer.
Some are made specifically for outdoor
or indoor use.
17. Boom Microphones
Is highly directional and has a far reach
with little loss of presence.
Is usually suspended from some kind of
boom or is handheld with your arms
acting as a boom.
18. Headset Microphone
The headset microphone consists of a
small but good-quality omni- or
unidirectional mike attached to
earphones.
19. Wireless Microphones
For use in situations in which complete
and unrestricted mobility of the sound
source is required.
Can be handheld or lavaliere mikes.
20. Desk Microphone
Microphones put on tables or desks.
Used for voice pickup only.
21. Stand Microphones
Stand microphones are used whenever
the sound source is fixed and the type
of programming permits them to be
seen.
Can be dynamic, ribbon, or condenser.
22. Hanging Microphones
The microphone is hung by its cable.
Does not usually produce the best
sound quality.
27. Handheld & Fishpole Boom
The most common ways of using the
boom mike in small studio productions
or in the field are to hold it by hand or
to suspend it from a fishpole boom.
28. Fishpole Boom
A fishpole boom is an extendible metal
pole that lets you mount a shotgun
mike. It is used mostly outdoors but can
be used in a studio.
Fishpoles are relatively easy to handle
but using long fishpoles can be tiring.
30. Giraffe Boom
Also called the tripod boom.
A small boom used by most studios.
An extendable horizontal boom arm
that is mounted on a tripod dolly.
31. The Big Boom
Also called the Perambulator Boom.
Used in large studio production.
Requires two operators.
A boom operator who works the
microphone boom
The dolly operator who helps reposition the
whole boom assembly.
32. When to use a Lavaliere
Indoor and outdoor news production.
Interviews
Panel Shows
Instructional Shows
In-studio television dramas
Music
33. Disadvantages
Not close to the mouth so it picks up outside
noise.
Each person must wear their own.
Wired lavaliers restrict mobility.
May pick up rubbing noises from clothing it is
attached to.
If clothing generates static electricity, the
discharge may be picked up as loud, sharp
pops.
35. Outdoor Use
Attach the windscreen.
Cheesecloth can be used as a
windscreen.
36. Good Quality Audio
Three simple tips for recording better-sounding
audio:
1. Stay close to the subject.
2. Minimize background noise.
3. Direct silently.
37. Stay Close to the Subject
When using a camera’s build in
microphone (mike), stay as close as
possible to the subject.
The farther away the microphone is,
the more interfering background noise
will be heard.
38. Minimize Background Noise
Set up your shoot so that the camera is
aimed away from major noise sources.
Do not place talent in front of a busy
street because the mike will be pointed
directly at the traffic noise behind them.
Instead, position your subjects so that
the camera mike points away from the
traffic.
39. Direct Silently
Do not give verbal instructions from the
camera position while recording.
Camera mikes pick up sounds to the
sides as well as in front.
40. Audio
Audio: The sound components of an
audiovisual program.
44. Voiceover
Voiceover: Narration or dialogue
recorded independently and then paired
with related video.
45. Equalization
Equalization: The adjustment of the
volume levels of various sound
frequencies to balance the overall
mixture of sounds.
46. Mixing
Mixing: The blending together of
separate audio tracks, either in a
computer or through a sound mixing
board.
47. Production Track
Production track: The “live” sound
recorded with the video.
48. Straight Cut
Straight cut: An edit in which audio and
video change simultaneously. Also, an
edit that does not include an effect
such as a fade or dissolve.
49. Split Edit
Split edit: A cut in which audio and
video do not change together.
When “audio leads” the sound with the
incoming video is heard over the end of
the outgoing video; when “video leads”
the sound with the outgoing video
continues over the incoming video.
