Class integrated_vec

class integrated_vec<T> dsp

template <typename T>
struct integrated_vec : public univector<T> { … }

Buffer of momentary mean-square energies used to compute the integrated (program) loudness per EBU R128 §3560.

Samples below -70 LUFS are discarded on push. The integrated value is computed lazily and cached: it is the mean of the energies that lie above a relative gate set 10 LU below the ungated mean.

constructor integrated_vec<T>() 

integrated_vec()

Fully qualified name: kfr::integrated_vec<T>::integrated_vec<T>()

Declared at dsp/ebu.hpp:113

function push(T) 

void push(T mean_square)

Append a momentary mean-square energy sample.

Samples whose loudness is below -70 LUFS (absolute gate) are rejected.

Parameters
mean_square Momentary mean-square energy for one 400 ms window.

Fully qualified name: kfr::integrated_vec<T>::push(T)

Declared at dsp/ebu.hpp:120

function reset() 

void reset()

Clear the buffer and invalidate the cached result.

Fully qualified name: kfr::integrated_vec<T>::reset()

Declared at dsp/ebu.hpp:130

function get() 

T get() const

Return the integrated loudness in LUFS, recomputing if needed.

Fully qualified name: kfr::integrated_vec<T>::get()
