The Bandpass effect module filters low and high frequencies, as shown in this frequency response graph:
The equation is y(n) = x(n) - x(n-2) - 0.25 y(n-2), where y is the output and x the input.
The response is that of a bandpass filter, with two zeros at z=±1 and two poles at z=±0.5i.
Part of the SoundEffects Effects Package.
