Frequency
For PEAK lters, this is the center frequency of the peak or dip. For HIGH_SHELF and LOW_SHELF lters, this is the
frequency at which the gain is half of the set value. For ALL_PASS lters, this is the center frequency of the phase shift.
Gain
For PEAK lters, this is the gain in dB at the center frequency. For HIGH_SHELF and LOW_SHELF lters, this is the gain
in dB reached at high or low frequencies respectively. A lter has no effect if its gain is set to 0 dB. Gain can be
adjusted in increments of 0.1 dB up to +/- 16 dB. This item is not present for the ALL_PASS lter type.
Q
Q controls the "sharpness" of the lter. For PEAK lters, lower Q gives a broader peak or dip, while higher Q gives a
narrower peak or dip. For HIGH_SHELF and LOW_SHELF lters, Q controls how quickly the lter transitions from no
gain to maximum gain. For ALL_PASS lters, higher Q gives a steeper phase transition.
Filter type
Selects the type of lter:
PEAK
Create a dip or a peak in the frequency response.
LOW_SHELF
Reduce or increase part of the frequency spectrum below a given frequency.
HIGH_SHELF
Reduce or increase part of the frequency spectrum above a given frequency.
ALL_PASS
Create a phase shift across the frequency band. This can be useful for correcting phase issues and for simulating
analog crossovers.
