Quiz 2

Question 1

Amplitude

Answer 1

The size of a sound vibration (height of wave), this determines how loud the sound is. Measured in decibels.

Question 2

Automation

Answer 2

In GarageBand, automatically changing some effect such as volume over time.

Question 3

Bit depth

Answer 3

The number of bits of info available for each sample. The higher the bit depth, the better the quality, but the larger the file size.

Question 4

Clipping

Answer 4

Distortion caused when the volume level exceeds the maximum that can be accurately produced.

Question 5

Close ended questions

Answer 5

Interview questions that result in short, mostly unusable responses

Question 6

Crossfade

Answer 6

A transition between two pieces of audio. The edit consists of fading out one source while fading in another. This method creates a smooth transition bc for a short period of time the listener hears both files playing simultaneously

Question 7

dB

Answer 7

Decibel- unit of measure for the volume or loudness of a sound. The decibel scale is a logarithmic scale in which 1dB is approximately the smallest change in volume audible to human ears

Question 8

Ducking

Answer 8

Decreasing the volume of one track so it “ ducks” under other tracks

Question 9

Fade in

Answer 9

A smooth transition from silence to normal volume

Question 10

Fade out

Answer 10

A smooth transition from normal volume to silence

Question 11

Fade under

Answer 11

A smooth transition from normal volume to background volume

Question 12

Field recording

Answer 12

Recording audio on location (outside the studio)

Question 13

Frequency

Answer 13

The speed of a sound vibration (length of wave), this determines the pitch of the sound. Measured in Hertz (Hz) or Kilohertz( kHz). The human hearing range is 20Hz- 20kHz

Question 14

Gain

Answer 14

Measurement of audio signal output;volume

Question 15

Loop

Answer 15

Prerecorded bits of music or instruments that can be repeated and combined to build longer audio compositions

Question 16

Mix down

Answer 16

The final edited version of an audio project. When finished editing in GarageBand, you export a final mix down of the audio file

Question 17

Mp3

Answer 17

A compressed audio format. Much smaller than the AIFF format, it typically requires about 1MB of disk space per minute of song

Question 18

Mute

Answer 18

In GarageBand, to completely silence a track

Question 19

Natural sound

Answer 19

The ambient noise of a location. Some natural sound is good, it paints a picture of the location. Too much is not good, it competes with the subject audio.

Question 20

Open ended questions

Answer 20

Interview questions which force the respondent to answer in complete sentences and produce usable sound bites

Question 21

Panning

Answer 21

Shifting back and forth between the left and right channels

Question 22

Playhead

Answer 22

In GarageBand, the thin red line topped with an inverted triangle which indicates what part of the audio is currently playing. It can also be used to jump to a point in the audio and or select a point for editing.

Question 23

Room tone

Answer 23

The relative quiet of a given location (each location has its own unique room tone). Always record a minute of room to cover any silence in the finished edit.

Question 24

Sample rate

Answer 24

How often a sound is sampled in 5e digitization process. The number of samples per unit of time (usually seconds) taken from an audio signal. (A sampling rate of 44.1kHz equals 44 thousand samples per second)

Question 25

Solo

Answer 25

To isolate a track, muting all others

Question 26

Sonic ID

Answer 26

Brief audio vignette that highlights the people, places, and events that make up a given region. They also identify the station with a phrase such as you’re listening to…

Question 27

Soundbite

Answer 27

The relatively short quote from a longer interview that you shows to use.

Question 28

“Stepping on” interview answers

Answer 28

Speaking over top of the interviewees responses during an interview. This can ruin an otherwise good soundbite.

Question 29

Track

Answer 29

In GarageBand, each track usually carries a separate musical instrument; you can independently adjust each tracks volume, Pan, and effects without effecting other tracks in the song.

Question 30

Using silence

Answer 30

An interviewing technique in which the interviewer remains silent to encourage the interviewee to continue talking.

Question 31

Volume

Answer 31

The perceived loudness of a sound (amplitude), measured in decibels

Question 32

Waveform

Answer 32

A two dimensional image representing an audio signal. The larger the spikes represent higher volumes. In GarageBand, waveforms give the user a visual idea of what has been recorded and where to make edits.
