/*
** ------------ 32-bit floating-point audio channel mixer ------------
** (Note: Mixing macros can be found in ft2_mix_macros.h)
**
** Specifications:
** - Interpolation: None, 2-tap linear, 4-tap/6-tap cubic Hermite, 8-tap/16-tap windowed-sinc
** - FT2-styled linear volume ramping (can be turned off)
** - 32.32 fixed-point precision for resampling delta/position
** - 32-bit floating-point precision for mixing and interpolation
**
** This file has separate routines for EVERY possible sampling variation:
** Interpolation type, volume ramp on/off, 8-bit/16-bit sample, loop type.
**
** Every voice has a function pointer set to the according mixing routine on
** sample trigger (from replayer, but set in audio thread), using a function
** pointer look-up table. All voices & pointers are always thread-safely cleared
** when changing any of the above attributes from the GUI, to prevent possible
** thread-related issues.
