EQ Mode
Description
L Cut =
Low Cut
(high pass)
Filter
Pass frequencies above the cutoff frequency, and progressively attenuate
frequencies below the cutoff frequency.
Gain parameter is not used here.
Frequency is the lowest frequency that will pass through the filter for this
band. Anything below this is cut out.
Q controls the level of boosting or attenuation at and around the cut off
frequency. Values above 1 boost the level of the audio signal at the cutoff
frequency. Values below 1 attenuate the level of the audio signal at the
cutoff frequency.
L Shelf =
Low Shelf
Filter
Cut or boost frequencies below the cutoff frequency. Above the cutoff,
signal will not be altered and will pass normally.
Gain controls the amount of boosting or attenuation that happens near and
below the selected frequency.
This filter impacts the audio signal near and below the selected frequency.
Q controls the shape of the gain adjustments made at the selected
frequency. Set to 1 or lower to have a shelf shape to the frequency
response. Values above 1 cause gradually sharper rises and drops on either
side of the selected frequency.
Param =
Parametric
Filter
Boost or attenuate the gain for a series of bands around the selected center
frequency.
Gain is the amount of attenuation or boosting that is applied at the
selected frequency.
Frequency is the center frequency of the affected band.
Q controls the width and shape of the band affected.
H Shelf =
High Shelf
Filter
Cut or boost frequencies above the cutoff frequency. Below the cutoff,
signal will not be altered and will pass normally.
Gain controls the amount of boosting or attenuation that happens near and
above the selected frequency.
This filter impacts the audio signal near and above the selected frequency.
Q controls the shape of the gain adjustments made at the selected
frequency. Set to 1 or lower to have a shelf shape to the frequency
response. Values above 1 cause gradually sharper rises and drops on either
side of the selected frequency.
H Cut =
High Cut
(lows pass)
Filter
Pass frequencies below the cutoff frequency, and progressively attenuate
frequencies above the cutoff frequency.
Gain parameter is not used here.
Frequency is the highest frequency that will pass through the filter.
Anything above this is cut out.
Q controls the level of boosting or attenuation at and around the cut off
frequency. Values above 1 boost the level of the audio signal at the cutoff
frequency. Values below 1 attenuate the level of the audio signal at the
cutoff frequency.
