Member Data Documentation

active_bands

template<typename SampleType>

std::uint32_t pulp::signal::SpectralBandLayoutT< SampleType >::active_bands = 32

bands

template<typename SampleType>

std::array<SpectralBandT<SampleType>, kSpectralBandMaskMaximumBands> pulp::signal::SpectralBandLayoutT< SampleType >::bands {}

boundary_kernel

template<typename SampleType>

SpectralMaskBoundaryKernel pulp::signal::SpectralBandLayoutT< SampleType >::boundary_kernel

Initial value:

=
        SpectralMaskBoundaryKernel::raised_cosine

edge_policy

template<typename SampleType>

SpectralBandEdgePolicy pulp::signal::SpectralBandLayoutT< SampleType >::edge_policy = SpectralBandEdgePolicy::mute_outside

max_hz

template<typename SampleType>

SampleType pulp::signal::SpectralBandLayoutT< SampleType >::max_hz = SampleType{20000}

min_hz

template<typename SampleType>

SampleType pulp::signal::SpectralBandLayoutT< SampleType >::min_hz = SampleType{20}

spacing

template<typename SampleType>

SpectralBandSpacing pulp::signal::SpectralBandLayoutT< SampleType >::spacing = SpectralBandSpacing::logarithmic

transition_fraction

template<typename SampleType>

SampleType pulp::signal::SpectralBandLayoutT< SampleType >::transition_fraction = SampleType{0.08}

Half-width of each boundary transition as a fraction of one band in the selected coordinate system.

0 is a hard step; 0.5 lets adjacent transitions meet at band centers without overlapping.

transition_frames

template<typename SampleType>

std::uint32_t pulp::signal::SpectralBandLayoutT< SampleType >::transition_frames = 4

Requested frame-domain transition duration.

The static builder stores this metadata; a streaming processor owns interpolation over time.

version

template<typename SampleType>

std::uint64_t pulp::signal::SpectralBandLayoutT< SampleType >::version = 0
