enum class TFractionalImpulse : unsigned int;
Set of predefined FIR allpass filters suitable for fractional delay filtering. Filter specifications have been relaxed to allow variation of the amplitude in the stop band between 0 and 1 linear scale, but keeping the ripple specification in the passband. When unclear what to select, falp_60dB is recommended.
