Functions
Value	nk::signal::hilbert (const Value &x, std::pmr::memory_resource *mr=nullptr)
	Analytic signal via the discrete Hilbert transform.
Value	nk::signal::envelope (const Value &x, std::pmr::memory_resource *mr=nullptr)
	Amplitude envelope of a real signal: |hilbert(x)|.
std::pair< Value, Value >	nk::signal::envelope_pair (const Value &x, std::pmr::memory_resource *mr=nullptr)
	2-output envelope (DC-symmetric form).
std::pair< Value, Value >	nk::signal::envelope_full (const Value &x, int mode, std::size_t n, std::pmr::memory_resource *mr=nullptr)
	Full multi-mode envelope computation.
