func MakeBandPass(h []float64, wf window.Func, stop1, stop2 float64)

MakeBandPass creates a band-pass filter impulse response. It allows frequences between the two stop frequencies.

func MakeBandReject(h []float64, wf window.Func, stop1, stop2 float64)

MakeBandReject creates a band-reject filter impulse response. It filters out frequencies between the two stop frequencies.

func MakeHighPass(h []float64, wf window.Func, cutoff float64)

MakeHighPass creates a high-pass filter impulse response. It filters frequencies lower than the cutoff frequency.

func MakeLowPass(h []float64, wf window.Func, cutoff float64)

MakeLowPass creates a low-pass filter impulse response. It filters frequencies higher than the cutoff frequency.
