Interested about library, but confused about usability

[mavavilj]

I am interested in utilizing this library, but I'm finding it very difficult to proceed, because there are no comments or examples.

I am seeking a spectrogram implementation and of course I started to read:

ciglet/ciglet.c

Line 1085 in 895ba9b

void cig_stft_forward(FP_TYPE* x, int nx, int* center, int* nwin, int nfrm,

and then

ciglet/test/test.c

Line 332 in 895ba9b

static void test_spectral(FP_TYPE* x, int nx, int fs, int nbit) {

But I'm finding it very difficult to infer by reading the code, what is done.
