Detailed Description

template<typename SampleType>
struct pulp::signal::SpectralBandResolutionT< SampleType >

Control-side report of how discrete FFT bin centers represent an authored viewport.

owned_bins counts only bins inside the viewport; exterior bins assigned through extend_edge_band do not inflate the first or last band. A zero count means that changing the corresponding hard-boundary band cannot directly select a distinct bin at this FFT geometry.
