signalsmith::delay::InterpolatorKaiserSincN< Sample, n, minimumPhase > Struct Template Reference

#include <delay.h>

Detailed Description

template<typename Sample, int n, bool minimumPhase = false>
struct signalsmith::delay::InterpolatorKaiserSincN< Sample, n, minimumPhase >

Fixed-size Kaiser-windowed sinc interpolation.

aliasing and amplitude/delay errors for different sizes

If minimumPhase is enabled, a minimum-phase version of the kernel is used:
