Detailed Description

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

One complete control-rate spectral-feature window.

Centroid and rolloff are in Hz. Flatness and flux are dimensionless in [0, 1]. The first valid window has zero flux because it has no predecessor. A silent window is emitted with finite zero-valued features and valid=false.
