Reference r2 FFT code
static size_t const kMaxN = 2048; // This is the largest straight FFT we support
struct complexf
{
float re;
float im;
complexf() {}
complexf(float r) : re(r), im(0.0f) {}
complexf(float r, float i) : re(r), im(i) {}

midi notes and closest corresponding tones that the game boy can generate, along with the difference in frequency between the midi note and the actual game boy frequency. more or less the same thing as http://www.devrs.com/gb/files/sndtab.html but in a friendlier format. more info and math on pandocs https://gbdev.io/pandocs/Audio_Registers.html

Below I collected relevant links and papers more or less pertaining to the subject of tetrahedral meshes.
It's an ever-growing list.
