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