5.5.7 Bandpass
Bandpass Filter BPF
Bandpass lters combine a highpass and a lowpass lter: they dampen all frequencies that
lie outside a particular frequency range dened by two cutoff frequencies (or by a middle
frequency and a bandwidth). This means that this particular frequency range is allowed to
pass through, whilst lower and higher frequencies outside the range are suppressed.
Main Panel
ABSYNTH 5’s bandpass lter BPF has the following parameters:
• FrequencycontrolandFrequencymenu: The Frequency control allows you to set the
middle frequency in semitones (Trans) or in Hertz (Hz), upon the selection in the nearby
Frequency menu.
• Qcontrol: Sets the bandwidth of the lter around the middle frequency. Its values go from
0 to 1000Hz.
• Dampingcontrol: Allows you to balance out any level uctuations introduced by the lter
(in dB).
