nk::signal::udecode
Value udecode(const Value &u, int N, double V=1.0, bool wrapOnOverflow=false, std::pmr::memory_resource *mr=nullptr)
Decode integer data back to double with peak ±V (y = udecode(u, N, V, overflow)).
nk::signal::uencode
Value uencode(const Value &u, int N, double V=1.0, bool signedOutput=false, std::pmr::memory_resource *mr=nullptr)
Quantise and encode u as N-bit integers (y = uencode(u, N, V, type)).
