Member Function Documentation

process()

template<typename SampleType = float>

BandSplit pulp::signal::LinkwitzRileyT< SampleType >::process ( SampleType input )

inline

reset()

template<typename SampleType = float>

void pulp::signal::LinkwitzRileyT< SampleType >::reset ( )

inline

section_coefficients()

template<typename SampleType = float>

SectionCoefficients pulp::signal::LinkwitzRileyT< SampleType >::section_coefficients ( ) const

inline

Coefficients shared by both cascaded sections of each LR4 branch.

set_frequency()

template<typename SampleType = float>

void pulp::signal::LinkwitzRileyT< SampleType >::set_frequency ( SampleType hz, SampleType sample_rate )

inline

set_frequency_precise()

template<typename SampleType = float>

void pulp::signal::LinkwitzRileyT< SampleType >::set_frequency_precise ( SampleType hz, SampleType sample_rate )

inline

Exact Butterworth alignment for new LR4 constructions.

The two-argument overload retains its historical rounded-Q coefficients for render compatibility with existing consumers.

set_section_coefficients()

template<typename SampleType = float>

void pulp::signal::LinkwitzRileyT< SampleType >::set_section_coefficients ( const SectionCoefficients & coefficients )

inline

Change coefficients without clearing recursive state.

This lets several phase-related LR4 paths receive one identical coefficient design.
