Flashcards in Test 3 Deck (53):
When was the first magnetic tape recorder introduced?
1934 - Germany
A reverb unit is a device that simulates what?
Tape speed of analog recording affects what?
sound quality and pitch (the faster the speed, the better the sound)
Time processors alter what?
time relations to signal (reverb/delay)
Alters dynamic range dependent of ratio/react text
hold output level to or below present point (a limiter is a kind of compressor)
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
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
The LP changed the record business because...
it shifted focus from the individual songs to the album collection
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)
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
What happens when an analog tape is copied over and over?
the quality goes down as you add noise from each analog machine
What is the purpose of "sel-sync"?
allows for overdubbing
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
When using an equalizer, what term describes the range of affected frequencies at a selected frequency?
What is the order of magnetic heads on an ATR from left to right?
erase, record, playback
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
What was the first "concept album" and why was it successful?
1953, Arthur Godfreys TV Calendar Show; Wanted CBS to get credit, not NBC
What is an expander and what type of processor is it?
It's an AMP. Gain decreases as input levels decrease. LOWERS DYNAMIC RANGE
What was the original intent of the LP?
a medium for classical music twenty minutes or longer (classical music/symphonies)
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
When was the magnetic wire recorder patented? By Who?
1898 by Poulsen
When was the first practical form of magnetic tape introduced? By Who?
What were the contributions of Smith?
thought up ribbon wire magnetized and record and playback electromagnetically
What were the contributions of Poulsen?
patented magnetic wire recorder
what were the contributions of Mullin?
smuggled the tape machine into the US from Germany
what were the contributions of Crosby?
first radio broadcast from tape
What were the contributions of Les Paul?
amplified the guitar; first full body electric guitar; invented multitrack recording
Describe how tape recorders appeared in the U.S.
John Mullins stole it from Germany and smuggled it back to the US
When did the first tape recording take place and where?
1936, Germany, London Philharmonic Orchestra
Les Paul married Iris Colleen Summers, or _________ ________, and while recording at home, virtually recorded in _______________.
Mary Ford; every room in the house
Initially, recording multiple parts on tape was not called multi-track recording, but called ____________ ____ _____________ recording.
Sound on Sound Recording
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
Not long after hanging up his hat in 1965, _______ __________ persuaded him to record a duet album at what studio? _____________________
Chet Adkins; RCA Studio B
Les finally convinced what guitar company to manufacture his guitar in 1951?
List the 4 controls on a compressor.
Threshold, attack, release, makeup gain
What ratio is a good starting point for recording vocals?
2:1 or 3:1
What section on the input module is a spectrum processor?
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
What type of EQ is more ‘musical’?
Microphone changes energy from...
acoustic to electric
playback tape head changes energy from....
magnetic to electric
cochlea changes energy from...
mechanical to electric
speaker changes energy from...
electric to acoustic
record tape head changes energy from...
electrical to magnetic
ear drum changes energy from....
sound/acoustic to mechanical
Electric energy flowing through a circuit is known as:
separate input, output, and monitor sections
input and output and some monitor functions are located within a single I/O module
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
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
What are the 3 basic console sections?
Input Section, Output Section, Monitor Section
