Detailed Description

template<typename SampleType = float>
class pulp::signal::ChebyshevHarmonicShaperT< SampleType >

A fixed-storage Chebyshev-series transfer function.

Coefficient zero is intentionally unavailable: every polynomial is translated by its value at zero so digital silence remains silence even when even harmonics are active. Inputs are constrained to the Chebyshev design domain [-1, 1]; the alias policy also band-limits the resulting boundary corners unless raw off mode is selected.
