Constructor & Destructor Documentation

◆ CosineFilter() [1/2]

CosineFilter::CosineFilter ( )

Constructs a CosineFilter object.

Definition at line 66 of file cosinefilter.cpp.

◆ CosineFilter() [2/2]

CosineFilter::CosineFilter	(	int	fftLength,
		float	lowpass,
		float	lowpass_width,
		float	highpass,
		float	highpass_width,
		double	sFreq,
		TPassType	type )

Constructs a CosineFilter object.

Parameters

[in]	fftLength	length of the fft (multiple integer of 2^x).
[in]	lowpass	low cutoff frequency in Hz (not normed to sampling freq).
[in]	lowpass_width	determines the width of the filter slopes (steepness) in Hz (not normed to sampling freq).
[in]	highpass	highpass high cutoff frequency in Hz (not normed to sampling freq).
[in]	highpass_width	determines the width of the filter slopes (steepness) in Hz (not normed to sampling freq).
[in]	sFreq	sampling frequency.
[in]	type	filter type (lowpass, highpass, etc.).
