Audio Production Review Powerpoint

1. Audio Production
Unit Review

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.

10. Foldable
 In your own words write a definition for
 Dynamic Microphones

3. Boom
4. Headset
5. Wireless

14. Stationary Microphones
1. Desk
2. Stand
3. Hanging
4. Hidden
5. Long-Distance

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.

23. Hidden Microphones
 Lavalier microphones can be hidden in
or behind objects.

24. Long-Distance Microphones
 When a microphone, such as a shotgun
mike, is placed in a location and pointed
at something in the distance.

25. Boom Microphones
Types of Boom Microphones
 Handheld shotgun
 Fishpole Boom
 The giraffe or tripod boom
 The big or perambulator boom

26. Boom Microphones
 You Tube

 Videomaker - Boom Mikes

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.

34. Advantage of Lavaliere
 Do not have to light around a boom to
avoid shadows.

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.

41. Sound
 Sound: The noises recorded as audio.

42. Sound Effects
 Sound effects: (SFX) Specific noises
added to a sound track.

43. Dialogue
 Dialogue: Speech by performers on-
screen.

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.
