bpass1~ band-pass filter Like apass2~, this second-order IIR band-pass filter computes coefficients for a biquad~. A band-pass filter only lets a certain band of frequencies pass through it. The band is defined by a center frequency and a bandwidth (usually the width in Hz where the volume on either side of the center frequency is attenuated by -3dB). Anyone who has worked with an analog bandpass filter will quickly understand what to do with it!
