configure()

template<typename SampleType = float>

bool pulp::signal::FilterMorphT< SampleType >::configure ( SampleType sample_rate, Endpoint first, Endpoint second )

inlinenoexcept

Transactionally design both endpoints.

Invalid input leaves the live filters and their state untouched. Call only at a block boundary.

configured()

template<typename SampleType = float>

bool pulp::signal::FilterMorphT< SampleType >::configured ( ) const

inlinenodiscardnoexcept

first_coefficients()

template<typename SampleType = float>

BiquadCoefficientsT< SampleType > pulp::signal::FilterMorphT< SampleType >::first_coefficients ( ) const

inlinenodiscardnoexcept

first_endpoint()

template<typename SampleType = float>

Endpoint pulp::signal::FilterMorphT< SampleType >::first_endpoint ( ) const

inlinenodiscardnoexcept

latency_samples()

template<typename SampleType = float>

constexpr int pulp::signal::FilterMorphT< SampleType >::latency_samples ( )

inlinestaticconstexprnoexcept

magnitude()

template<typename SampleType = float>

double pulp::signal::FilterMorphT< SampleType >::magnitude ( double frequency_hz ) const

inlinenodiscardnoexcept

Exact complex parallel sum of the two live sections.

magnitude_db()

template<typename SampleType = float>

float pulp::signal::FilterMorphT< SampleType >::magnitude_db ( double frequency_hz ) const

inlinenodiscardnoexcept

morph()

template<typename SampleType = float>

SampleType pulp::signal::FilterMorphT< SampleType >::morph ( ) const

inlinenodiscardnoexcept

process()

template<typename SampleType = float>

SampleType pulp::signal::FilterMorphT< SampleType >::process ( SampleType input )

inlinenoexcept

process_block() [1/2]

template<typename SampleType = float>

bool pulp::signal::FilterMorphT< SampleType >::process_block ( const SampleType * input, SampleType * output, std::size_t frames )

inlinenoexcept

process_block() [2/2]

template<typename SampleType = float>

bool pulp::signal::FilterMorphT< SampleType >::process_block ( SampleType * samples, std::size_t frames )

inlinenoexcept

reset()

template<typename SampleType = float>

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

inlinenoexcept

response_curve_db()

template<typename SampleType = float>

void pulp::signal::FilterMorphT< SampleType >::response_curve_db ( double min_hz, double max_hz, std::span< float > output ) const

inlinenoexcept

sample_rate()

template<typename SampleType = float>

SampleType pulp::signal::FilterMorphT< SampleType >::sample_rate ( ) const

inlinenodiscardnoexcept

second_coefficients()

template<typename SampleType = float>

BiquadCoefficientsT< SampleType > pulp::signal::FilterMorphT< SampleType >::second_coefficients ( ) const

inlinenodiscardnoexcept

second_endpoint()

template<typename SampleType = float>

Endpoint pulp::signal::FilterMorphT< SampleType >::second_endpoint ( ) const

inlinenodiscardnoexcept

set_morph()

template<typename SampleType = float>

bool pulp::signal::FilterMorphT< SampleType >::set_morph ( SampleType amount )

inlinenoexcept

Set the linear-amplitude morph position.

A convex output blend avoids hidden midpoint gain and keeps the canonical endpoint normalizations.

tail_samples()

template<typename SampleType = float>

constexpr int pulp::signal::FilterMorphT< SampleType >::tail_samples ( )

inlinestaticconstexprnoexcept

Recursive biquads have an asymptotic (formally unbounded) tail.
