Flashcards in Test 3 Deck (53):
1

When was the first magnetic tape recorder introduced?

1934 - Germany

2

A reverb unit is a device that simulates what?


acoustic environments

3

Tape speed of analog recording affects what? 


sound quality and pitch (the faster the speed, the better the sound)

4

Time processors alter what?


time relations to signal (reverb/delay)

5

Compressor

Alters dynamic range dependent of ratio/react text

6

Limiter-

hold output level to or below present point (a limiter is a kind of compressor)

7

High Pass Filter:

low cut filter; frequencies above the cutoff point are allowed to pass through, frequencies below the cutoff point are attenuated; filter skirt is the region of the filter spectrum to the left of the cutoff frequency/lower than the cutoff frequency

8

Low Pass Filter:

high cut filter; frequencies below cutoff point are allowed to pass and frequencies above cutoff point are attenuated; filter skirt is the region of the spectrum to the right of the cutoff frequency/higher than the cutoff frequency

9

The LP changed the record business because... 


it shifted focus from the individual songs to the album collection

10

What is a noise gate and what type of processor is it?


it’s an EXPANDER, can reduce or eliminate low levels of sounds w/o affecting wanted sounds (mutes signal after present time)

11

Why was it so difficult to develop a successful LP disc? 


Materials kept breaking, head to reduce RPM, Figure out how to make grooves smaller, had to figure out how to make discs bigger

12

What happens when an analog tape is copied over and over?


the quality goes down as you add noise from each analog machine

13

What is the purpose of "sel-sync"?


allows for overdubbing

14

Why should analog tape be stored "tails out"?


in order to prevent print through/that weird echo effect in the middle of songs, it creates a natural decay instead of pre-echo

15

When using an equalizer, what term describes the range of affected frequencies at 
a selected frequency?


bandwidth

16

What is the order of magnetic heads on an ATR from left to right? 


erase, record, playback

17

Who is credited with the development of the LP and why? 


Peter Goldmark in 1939, william bachman did the work but Paley could not admit his CBS labs were outdone with NBC release of the color TV system, so he publicly credited goldmark with the invention

18

What was the first "concept album" and why was it successful?

1953, Arthur Godfreys TV Calendar Show; Wanted CBS to get credit, not NBC

19

What is an expander and what type of processor is it?


It's an AMP. Gain decreases as input levels decrease. LOWERS DYNAMIC RANGE

20

What was the original intent of the LP? 


a medium for classical music twenty minutes or longer (classical music/symphonies)

21

Both record and playback heads of a tape recorder are transducers. Describe their function. 


Record heads: change electric to magnetic

playback heads: change magnetic to acoustic

22

When was the magnetic wire recorder patented? By Who?


1898 by Poulsen

23

When was the first practical form of magnetic tape introduced? By Who?


1934, BASF

24

What were the contributions of Smith?

thought up ribbon wire magnetized and record and playback electromagnetically

25

What were the contributions of Poulsen?

patented magnetic wire recorder

26

what were the contributions of Mullin?

smuggled the tape machine into the US from Germany

27

what were the contributions of Crosby?

first radio broadcast from tape

28

What were the contributions of Les Paul?

amplified the guitar; first full body electric guitar; invented multitrack recording

29

Describe how tape recorders appeared in the U.S. 


John Mullins stole it from Germany and smuggled it back to the US

30

When did the first tape recording take place and where?


1936, Germany, London Philharmonic Orchestra

31

Les Paul married Iris Colleen Summers, or _________ ________, and while 
recording at home, virtually recorded in _______________.


Mary Ford; every room in the house

32

Initially, recording multiple parts on tape was not called multi-track recording, but 
called ____________ ____ _____________ recording.


Sound on Sound Recording

33

Miles Davis asked Les Paul what he needed to do to get a hit record. Les advised 
him to play ________________, and to play for the ___________.


the melody; for the people

34

Not long after hanging up his hat in 1965, _______ __________ persuaded him to 
record a duet album at what studio? _____________________ 


Chet Adkins; RCA Studio B

35

Les finally convinced what guitar company to manufacture his guitar in 1951?


Gibson

36

List the 4 controls on a compressor. 


Threshold, attack, release, makeup gain

37

What ratio is a good starting point for recording vocals? 


2:1 or 3:1

38

What section on the input module is a spectrum processor? 


EQ

39

If I wanted to add overall ‘brightness’ to a recording, what type EQ would I use?


Use a shelve EQ and increase the high frequencies

40

What type of EQ is more ‘musical’? 


parametric

41

Microphone changes energy from...

acoustic to electric

42

playback tape head changes energy from....

magnetic to electric

43

cochlea changes energy from...

mechanical to electric

44

speaker changes energy from...

electric to acoustic

45

record tape head changes energy from...

electrical to magnetic

46

ear drum changes energy from....

sound/acoustic to mechanical

47

Electric energy flowing through a circuit is known as: 


current

48

Split/Split-section console

separate input, output, and monitor sections

49

In-line Console

input and output and some monitor functions are located within a single I/O module

50

What is the purpose of aux sends and returns on a console? 


AKA effects send/return; feeds input channel signal to another destination; mixed with or added to the original signal; insert points replace original sound

51

What is the difference between VU and PPM? 


VU (volume unit meter) measures average level

PPM (peak program meter) measures transient peaks

both reference audio passing through the console as voltage

52

What are the 3 basic console sections?


Input Section, Output Section, Monitor Section

53

What is a mixing "buss"?

allows selected channels to be grouped before they reach a master output; signal flow changes from vertical to horizontal; used in tracking and overdubbing to combine multiple signals or inputs to one output
