STB-style single header fast fourier transform C library primarily for visualizing frequencies

#defineFFT_IMPLEMENTATION#include"fft.h"intmain(void) {
signed short*samples; // allocate and fill upintnumber_of_samples=4096; // must be power of 2FFTValue*results= (FFTValue*) malloc(number_of_samples*sizeof(*results));
fft_process(results, number_of_samples, 1, samples, 0.5);
for (inti=0; i<number_of_samples; i++) {
floatvalue=fft_get_bar_value(results, number_of_samples, i, number_of_samples, 1);
// DrawFrequencyBar(i, value);
}
}
