Constructor & Destructor Documentation

BiquadBank() [1/2]

BiquadBank::BiquadBank	(	const dmat &	filters,
		const vd *	gains = nullptr
	)

Initialize biquadbank.

Parameters

filters	Filters for each filter in the bank. First axis isis the coefficient index, second axis is the filter index.
gains	Gain values. Given as pointer, if not given (nulltpr), gains are initialized with unity gain.

Make sure the pool is created once, such that all threads are ready for use.

Definition at line 120 of file lasp_biquadbank.cpp.

BiquadBank() [2/2]

BiquadBank::BiquadBank ( std::vector< SeriesBiquad >  filters, vd  gains  )

inline

Construct biquad bank from already given set of series biquad filters and gain values.

Parameters

filters	The filters to set
gains	The gain values for each filter

Member Function Documentation

clone()

std::unique_ptr< Filter > BiquadBank::clone ( ) const

finaloverridevirtual

Clone a filter, to generate a copy.

Returns

Copy of filter with state set to zero.

Implements Filter.

Definition at line 189 of file lasp_biquadbank.cpp.

filter()

void BiquadBank::filter ( vd &  inout )

finaloverridevirtual

Filter input, and provides output in same array as input.

Parameters

inout

Vector of input / output samples.

Implements Filter.

Definition at line 149 of file lasp_biquadbank.cpp.

nfilters()

us BiquadBank::nfilters ( ) const

inline

Returns the number of Filters.

Returns

The number of filters

Definition at line 100 of file lasp_biquadbank.h.

reset()

void BiquadBank::reset ( )

finaloverridevirtual

Reset filter state to 0 (history was all-zero).

Implements Filter.

Definition at line 182 of file lasp_biquadbank.cpp.

setGains()

void BiquadBank::setGains

(

const vd &

gains

)

Set new gain values for each filter in the BiquadBank.

Parameters

gains

Vector of gain values. Should be of same length as the number of filters installed.
