Cycle 1 Test Flashcards
The application of scientific and mathematical principles to achieve an end result
engineering
a room that is acoustically isolated from the studio and surround areas
control room
allows the engineer to combine, control, and distribute audio signals
console
a recorder that has three or more tracks to record to and play back from
multi-track recorder
a type of recorder to combine all the tracks to. could be mono, stereo, or surround
mixdown recorder
most important person in the studio
artist
an addition musician used for the project, who is not normally part of the main recording group
session musician
person in charge of the studio budget, studio booking, song arrangement, etc
producer
the process of editing, fixing, adding, or replacing tracks
overdubbing
any device that changes one form of energy into another corresponding form of energy
transducer
electrical level measured in milivolts
mic level
electrical level measured as 1.23 volts
line level
electrical level measured from 1-50 volts
speaker level
types of normals:
full, half, open, mult
wavelength formula
wavelength = v / f
wavelength is measured in
feet per cycle
frequency is measured in
cycles per second or hertz
to increase in amplitude
amplify
to decrease in amplitude
attenuate
one completed excursion of a wave
a cycle
greater than normal atmospheric pressure
compression
lesser than normal atmospheric pressure
rarefaction
amplitude is measured in
decibels
the time is takes to complete one cycle of a wave
period
the relationship between two or more waveforms, measured in degrees
phase
the difference in time of one waveform compared to another
phase shift
the absolute positive and negative values in a waveform, compared to another
polarity
define fundamental
the frequency of the note that is being played
whole numbers multiples of the funamental
harmonics
every time a frequency doubles in value, its called
an octave
a sound pressure wave’s ability to bend around objects
diffraction
what dB level is considered the best for listening?
85 dB SPL
Bell Labs engineers who established equal loudness contours of the human ear
fletcher + munsen
velocity at 70º farenheight
1130 feet per second
two basic ways to record
real-time, multitracking
three main steps of multitrack recording
recording, overdubbing, mixing
best operating device for audio devices is called
Nominal Level or 0dB
the area between nominal level and distortion
headroom
unwanted leakage between channels is called
crosstalk
three sections of a recording console
Input, Output, Monitor
four possible console inputs
Mic, Line, Tape, Group Signal on the I/O
Two paths on a console
Channel Path, Monitor Path
Two types of console layouts
In-Line, Split Monitor
define Buss
a common signal line
allows us to make multiple copies of a signal in parallel
a mult
a ____ normalled row breaks the input
half
a ____ normalled row breaks the input and output
full
two types of dynamic mics
dynamic moving coil, ribbon mic
dynamic microphones operate by using:
electromagnetic induction
condenser microphones operate by using:
electrostatic principle
what does ICA stand for? what does it do?
impedance conversion amplifier. lowers the output impedance from the mic and amplifies the output voltage to line level
a PAD on a microphone will increase the max
SPL
the three types of ribbon microphones
passive, active, tube
the technical term for omnidirectional
pressure operated
three types of unidirectional polar patterns
cardioid, supercardioid, hypercardioid
slang name for bi-directional polar pattern
figure-8
area where mic picks up the most sound
on-axis
area where the mic rejects the most sound
null-point
term for a pair of mics tested by the manufacturer to be exactly the same
matched pair
