All-pass filters are usually grouped by how sharp and flexible their phase shifts are: allpassphase
If your audio system suffers from unexplained "phase problems," consider these diagnostics: for (int i = 0; i < samples;
: IIR all-pass filters are generally more efficient than FIR filters in terms of memory and computational complexity when both frequency selectivity and phase response approximation are required. for (int i = 0
