Hi, could you please share some details about the algorithm that is used for high-pass filtering?
Looking at the code for the HighPass class, it appears that the library uses a second-order (Butterworth?) high-pass filter design. What is the phase distortion of this filter? Does the IIRFilter class provide a means for forward-backward filtering to cancel the phase distortion (similar to Python/Matlab filtfilt functions)?
