Detailed Description

removes the frequencies that are not in the provided frequency band.

Constructor & Destructor Documentation

◆ BandPassFilter() [1/2]

HephAudio::BandPassFilter::BandPassFilter ( )

creates a new instance and initializes it with default values.

◆ BandPassFilter() [2/2]

HephAudio::BandPassFilter::BandPassFilter	(	double	f1,
		double	f2,
		size_t	hopSize,
		const Window &	wnd )

creates a new instance and initializes it with the provided values.

Parameters

f1	first frequency.
f2	second frequency.
hopSize	number of frames to advance each iteration.
wnd	window that will be applied for overlap-add.

◆ ~BandPassFilter()

virtual HephAudio::BandPassFilter::~BandPassFilter ( )

virtualdefault

releases the resources and destroys the instance.
