Equalizers Flashcards
Low end
no standard for exactly what constitutes each frequency range, but generally considered 0-250Hz
Mid range
roughly 250-2kHz
Paragraphic equalizer
EQ that both shows you a graphic Hz chart and has the variability of a parametric EQ; ex. 7-Band EQ 3 Pro Tools
Parametric equalizer
allows for variable frequency selection, gain adjustment, and typically variable Q factor
Peaking filter/peaking EQ
also known as bell curve EQ; shape style for EQs that allow you to select a specific frequency to boost and it creates a “peak” at that frequency
Q
stands for quality factor; measurement of how wide a peaking filter is; Q= center frequency/bandwidth
Quasi-parametric equalizer (semi-parametric)
parametric EQ that does not allow for Q factor control
Resonance
boost around the cut-off Hz and gives an edge to the transition range
Scooped mids
all of the mid Hz in a sound are dramatically reduced with the use of an EQ
Shelf
EQ effect where frequencies above/below the set point are affected while all other frequencies remain un-affected
Shelving filter/shelving EQ
bass/treble controls which boost all frequencies above/below the cut-off Hz (or in this case “corner frequency”) at a uniform amount
Spectra
plural of spectrum
Spectral balance
balance between frequencies across the whole Hz range (lows to highs)
Spectrum
range from the lowest frequencies to the highest frequencies
Stop frequency
the band of frequencies being blocked by a filter
Symmetrical Q
the Q value/bandwidth of a filter is the same on both sides, symmetrical around the center frequency
Timbre
subjective tone quality/color of a sound
Tone
how one describes the sound quality of a particular sound in comparison to another sound of the same type
Top end
the high range of frequencies, roughly from 10kHz to 20kHz; provides clarity and openness to a sound
Turnover frequency
in a shelving filter, the frequency where a slope starts to level out and frequencies are attenuated at a constant slope
Warmth
description of mid Hz being more present than high Hz in a mix/sound
⅓ octave
the range of a band on a 31-band EQ, one-third of an octave apart based on center frequency
31 band
EQ usually used for sound reinforcement, usually with ⅓ octave bands
Constant Q
same Q amount regardless of the amount of boost or cut
Boost
increase in amplitude, usually within a specific frequency or frequency range
Bottom end
the lowest range of frequencies, usually used to make a sound more “full”
Center frequency
the middle frequency within a bandwidth of frequencies
Constant range
EQ with set bands that are not able to be changed
EQ curve
the shape of settings within a given EQ plugin or unit
Cut
an attenuation of amplitude, usually within a specific frequency range
Cut-only equalizer
EQ that does not boost frequencies, only attenuates them
Dynamic equalizer
amount of cut or boost of each band is determined by the gain intensity of each band; the louder or softer a specific band becomes, the less or more cut or boost is applied
Exciter
device that adds even-order harmonic distortion to a signal for the purpose of making it more audible in the presence of other sounds
Equalizer (EQ)
alters or distorts the relative strength of certain frequency ranges of an audio signal
Feathering
act of adding small amounts at the frequencies adjoining the main one, rather than applying a large amount of EQ at a single frequency
Fingerprint EQ
applying an existing EQ setting to another instrument, matching one sonic fingerprint to another signal
Flat
an even frequency response across the range of frequencies
Graphic EQ
frequency bands appear as faders or sliders instead of knobs; fixed frequency bands
High end
approximately 10kHz-20kHz
