49 Cards in this Set

  • Front
  • Back
idiophone
object that when interacted with, it will make a noise
aerophone
cylider that when air goes thru it, it will make a noise
membranophone
drum
chordaphone
guitar
speed of sound
is constant across the spectrum except when the temperature changes
3 to 1 rule
2 mics same distance from source, 3 times the distance from each other
volume
inpercise consumer term with no set definition in terms of sound
loudness
listners perception of what they hear
intensity
SPL-sound pressure level
crest factor
1. its really good for whitening your teeth
2. instanteneous rise from avarage to peak value
bit depth
is dynamic range, and discreet steps of resolution
0 on VU meter is how much on a digital signal meter
-18dbFS
nyquist filter
low pass filter
passband
useful portion of the spectrum
Haas Effect
two sounds have to be 30 msecs apart in order to be percieved as two sounds
benefit of using high sample rate
a less severe slope in a low pass filter results in less artifacts in the passband
DSD
direct stream digital
Dither
low level noise introduced into the signal.
Dither does
1. modulation of least significant bit
2. provides fake nosie floor
3. increases percieved dynamic range
bias
50k signal
George Massenberg
1967, invented parametric EQ
bandwidth
difference in 3db downpoints in octaves
Q
3db downpoints difference devided by the center frequency
IIR
infinite impulse response
FIR
Finite impulse response----prevents linear phase distortion
Gerzone
resonant shelf, it dips briefly before rising
Boxandall
continually rising curve
300hz-700hz
frequencies that make the mix sound really boxed
1khz-4khz
high frequencies of mixes, too much is harsh and irritating
musical bottom end
low frequency info that contains fundemental and or harmonic values that are realted to the rest of the musical program
NOS stereo mic technique
two cardiods 30cm apart, angled at 90 degrees,
analog tape has how much dynamic range?
70db
ADSR?
attack, decay, sustain, release--an envelope
Calibrated Monitor System
known system calibrated to a known frequency and amplitude response
clock
speed and accuracy with which samples are played
dynamic range
dynamic range of 24 bit audio is----24x6=144db
Noise Shaping
algorithm applied to dither, pushes dither noise into a frequency that cant be heard.
ORTF
Office of Radio Television Francios
parallel compression
taking the uncompressed signal and acompressed version of the signal mixing them tigether and getting an upward compression version of them
Ribbon test
used to asses your stereo field
speed of sound #
1130ft per sec
truncation
reduction of bit depth
7 essential components to D-Control
1. CPU
2.Console
3.192's
4.digi pres
5.midi i/o's
6.xmon
7.sync i/o
mics set to omni shall, or not suffer from close proximity effect
shall not
when does comb filtering become and issue
beyond 6ft
two mics 4 feet apart enforce pickup of what frequency?
280hz
2 mics 1 foot apart enforce pickup of what frequencies?
1khz
4 custom fader modes
1. custom fader groups
2. mix edit groups
3. master or tracks
4. plug ins mode
flip?
sends encoders to the faders, faders to encoders
