wave8.h File Reference

Detailed Description

Out-of-line declarations for wave8 transposition internals.

Split from the former detail/wave8.hpp force-inline header. Callers now include this .h and link against detail/wave8.cpp.hpp. Constexpr LUTs and the FL_WAVE8_SPREAD_TO_16 macro stay in this .h because they need to be visible at compile time; every function definition moves to the .cpp.hpp for one-per-program-image emit rather than per-TU inlining.
