Here’s a nice video explaining the various types of filters: https://www.youtube.com/watch?v=rkwS6vigSyE

Values:

BIQUAD_TYPE_LPF

Low pass filter – cuts high frequencies, allows low frequencies to pass

BIQUAD_TYPE_HPF

High pass filter – cuts low frequencies, allows high frequencies to pass

BIQUAD_TYPE_BPF

Band pass filter – cuts low and high frequencies outside of center/cutoff frequency of filter (like wah pedal)

BIQUAD_TYPE_NOTCH

Notch filter – cuts a specific frequency and lets other frequencies pass (basically opposite of a band-pass filter)

BIQUAD_TYPE_PEAKING

Peaking filter – increases or decreases gain at a specific frequency (like those used in parametric filters)

BIQUAD_TYPE_L_SHELF

Low shelf filter – lets all frequencies pass but increases or reduces frequencies below the shelf frequency by specified amount

BIQUAD_TYPE_H_SHELF

High shelf filter – lets all frequencies pass but increases or reduces frequencies above the shelf frequency by specified amount

BIQUAD_TYPE_TOTAL
